Introduction

While students and others may be excited to pursue a program of study to become aerospace engineers, the profession entails significant professional and ethical responsibilities. Numerous regulations and policies govern the design, certification, and operation of flight vehicles. In addition, established ethical practices and codes of conduct define how professional aerospace engineers are expected to perform their duties. Besides gaining technical qualifications and maintaining their technical competency,^[1] engineers must also adhere to the ethical principles of their profession. In this regard, engineers are expected to carry out their technical work with honesty and integrity, treat professional colleagues with respect, protect the public’s safety and welfare, and remain aware of their legal responsibilities, liabilities, and the potential consequences of their decisions.

The importance of ethical responsibility is also reflected in the expectations placed on engineering education. Accreditation bodies such as ABET require engineering graduates to recognize ethical and professional responsibilities in engineering contexts and to make informed judgments that consider the broader impacts of engineering solutions. For this reason, engineering programs must ensure that students not only develop strong technical skills but also understand the broader professional obligations associated with engineering work.

Modern engineering practice also requires awareness of the broader environmental and societal implications of engineering decisions. Engineers must comply with a wide range of local, state, national, and sometimes international regulations governing safety, environmental protection, and public welfare. These requirements may vary across jurisdictions and can impose competing constraints on cost, performance, and risk. Consequently, engineering practice frequently involves difficult technical and professional judgments made under conditions of uncertainty and constraint. Therefore, sound engineering practice demands both technical competence and ethical responsibility.

Engineers must also be aware of legal issues related to intellectual property, including copyright and the protections afforded under U.S. and international copyright law. In modern engineering practice, this awareness extends to the use of software and digital media, which are governed in part by the Digital Millennium Copyright Act (DMCA). The implications of noncompliance with copyright law are often underestimated, particularly among students and inexperienced engineers. Unauthorized use or distribution of copyrighted content, software piracy, or person-to-person (P2P) sharing of software or digital media can expose individuals and organizations to significant legal, financial, and reputational consequences. In particular, using unauthorized or pirated software within an organization can quickly become a serious legal matter.

Differences Between Morals and Ethics

Morals and ethics are often used interchangeably, but they have distinct meanings and must be carefully distinguished. On the one hand, morals refer to the principles or values that guide individuals or society in determining right from wrong. The word “morals” derives from the Latin moralitas, meaning “manner, character, or proper behavior.” It is the conduct or set of rules a person or community may follow, believing them to be obligatory. On the other hand, ethics is the systematic study of moral principles and their application across various contexts. The term “ethics” derives from the Greek ethikos, meaning “about character.” Ethics concerns what actions are morally right or wrong, the principles that should guide acceptable human behavior, and how individuals and organizations make reasoned judgments about responsible conduct.

In essence, morals are the values and principles that individuals or communities hold and follow, whereas ethics is the systematic study and critical examination of those principles and their application. Moral beliefs are often personal and shaped by culture, religion, upbringing, and experience, so they vary widely among individuals and societies. Ethics, by contrast, seeks a more reasoned, consistent framework for evaluating conduct, analyzing moral dilemmas, and guiding responsible decision-making in professional and societal contexts.

Therefore, ethics provides a framework for determining right from wrong within a particular context. Professional ethics seeks reasoned and consistent standards for evaluating conduct within a group, profession, or organization. A useful conceptual shorthand is

This expression is a mnemonic, not a mathematical relationship. Remember that ethics is fundamentally a form of moral philosophy, and philosophy is about reasoning.

Aerospace Code of Ethics

As in other professional fields, newcomers to aerospace engineering must be familiar with the code of ethics. The aerospace profession has evolved such codes of ethics over many decades, and they “establish the aerospace engineer’s standing concerning the public at large, their clients and employers, and the profession as a whole.” The general principles outlined in the codes of ethics are broadly similar across the world’s engineering societies and those established by other professional authorities. Furthermore, in some jurisdictions, professional codes or licensing rules are incorporated into regulatory frameworks and may become enforceable through disciplinary, civil, or criminal processes. Therefore, all engineers must know their respective codes of practice, regardless of location, and follow them in all engineering tasks and duties.

The following is a top-level list of Guidelines for Practice in the U.S. under the American Institute of Aeronautics and Astronautics (AIAA) Code of Ethics. The complete statement is available on the AIAA’s website at https://www.aiaa.org/CodeOfEthics/.

Facing Ethical Issues

Most engineers are likely to encounter ethical issues or dilemmas during their careers. Ethical dilemmas can be challenging to resolve because they involve decisions in situations with no single correct answer; each option will likely have negative consequences. The issue’s complexity is often heightened by uncertainty about the outcomes of those choices. Some of these issues may be technical, but others may be non-technical and involve broader considerations, including administrative, personnel, and possibly legal implications.

Consider the following examples, which may also prompt further discussion in a group setting.

1. Failure to follow practices, advice, or judgment

One example of an ethical dilemma an engineer may face is the duty to report a potential risk to others posed by a client or employer who fails to follow proper engineering practices, advice, or judgment. However, they may hesitate to speak up or fear retaliation, even when the conduct is unlawful. Whistleblower and anti-retaliation protections depend on the subject matter, industry, jurisdiction, and statute involved. Laws addressing discrimination complaints, workplace safety, fraud, aviation, government contracting, and other regulated activities may provide different protections and procedures. Engineers have a professional ethical duty to protect public safety and welfare, not any individual, employer, or organization. A professional engineer may be disciplined, and an employer may be sanctioned, if the loss of life or well-being can be traced to a failure to follow sound engineering practices or to any other practice connected to ethical misconduct. In addition, if ethical principles are part of regulatory law, as is often the case in many professions, including engineering, civil law, and criminal law, penalties may be imposed on all parties for severe misconduct. How might one navigate this issue ethically?

2. Honest and constructive criticism of technical work

Another ethical dilemma arises when an engineer must offer honest, constructive criticism of technical work, acknowledge and correct errors, and provide feedback that is both accurate and constructive. Engineers have a professional responsibility to uphold high standards of accuracy and integrity in technical work. For example, a peer-reviewed journal publication may contain errors or inaccuracies that should be brought to the authors’ attention and corrected in the journal, thereby improving the field’s overall quality. However, balancing the obligation to provide honest and constructive criticism with the risk of unintended professional harm to the authors can pose an ethical dilemma. How might one navigate this issue ethically? One approach to resolving this dilemma involves balancing ethical obligations to uphold the quality and integrity of technical work with consideration of potential harm to others. Approaching the situation with professionalism, empathy, and a focus on constructive improvement is the best way to resolve this dilemma.

3. Potential conflict of interest

Potential conflicts of interest are a common ethical concern in professional contexts. For example, consider an engineer working on a project to develop a new system for a spacecraft that their company manufactures under contract. The engineering team must select a supplier for a critical propulsion-system component under the contract. The engineer learns that one potential supplier is a company owned by a friend from college. They offer competitive pricing and claim to have the expertise to deliver the required components on schedule. However, you are aware of other concerns about the reliability and quality of this supplier’s products. Choosing your friend’s company as the supplier could create a conflict of interest, as it may compromise the objectivity and impartiality of the selection process. On the one hand, selecting this supplier could strengthen your relationship with your friend and benefit them financially. On the other hand, failing to deliver high-quality components on time may undermine the project’s integrity, jeopardize the spacecraft’s success, and damage your company’s reputation. How might one navigate this ethical conflict of interest?

4. Conflicts of Interest in Peer Review

Peer review is a cornerstone of engineering and scientific practice. Independent experts routinely evaluate research papers, technical reports, and funding proposals before publication or funding decisions are made. For the process to work properly, reviewers must provide objective, unbiased assessments based solely on the technical merits of the work. A fundamental ethical requirement in peer review is avoiding conflicts of interest (COI). A conflict of interest exists whenever a reviewer has a personal, professional, or financial relationship with the author or proposer that could influence, or even appear to influence, their judgment. Even if a reviewer believes they can remain impartial, the appearance of bias alone can undermine confidence in the review process.

One situation that frequently arises in academia involves the advisor-student relationship. A former graduate student may be invited to review a proposal or manuscript written by their former professor or research advisor. Because this relationship often involves close collaboration, intellectual mentorship, and professional dependence, most organizations regard it as a conflict of interest, especially when the relationship is recent. In practice, many funding agencies and journals consider a former advisor-student relationship within the past three to five years to constitute a significant conflict. During this period, the former student may still rely on the advisor for professional references, collaborations, or career advancement. In addition, the student may have contributed directly to the ideas or research program underlying the proposal or manuscript. These factors make it difficult to ensure that the review is fully independent.

For this reason, reviewers are expected to disclose such relationships and normally decline the review. The appropriate course of action is to inform the editor, program officer, or review organizer that a prior advisor-student relationship exists and to allow them to determine whether the review should proceed or be reassigned. Early-career engineers and researchers should recognize that declining a review under these circumstances is not unprofessional. On the contrary, transparency about potential conflicts is essential to professional integrity. Maintaining the credibility of the peer-review process depends on reviewers being willing to recuse themselves whenever their independence could reasonably be called into question by others.

Other Examples of Ethical Concerns

Other examples of ethical concerns for a professional engineer may include the following:

• Failure to separate professional and personal relationships with clients, consultants, contractors, or others.
• Possible forms of conflict of interest, i.e., a clash between self-serving interests and professional duties or responsibilities.
• Acts of bribery or the receipt of kickbacks.
• Improper treatment of confidential or proprietary information.
• Failure to ensure or advise on proper legal compliance by clients, contractors, and others.
• Conspiracy to defraud by impairing, obstructing, defeating, or interfering with lawful requirements.
• Conflicting outside employment, including activities such as “moonlighting.”
• Issues that may involve “quid pro quo,” i.e., one party gaining something of benefit for doing something else to benefit another party.
• Spreading disinformation. Typically defined as deliberately creating and sharing false or manipulated information intended to deceive and mislead others to protect self-interest, cause harm, or achieve financial gain.
• Employers, co-workers, or other individuals who intimidate employees in an attempt to discredit or punish those who dissent from their actions, opinions, or judgment.

Following ethical standards and fulfilling ethical responsibilities will generally address most initial concerns. However, the issues are not always so clear-cut, and resolving an ethical concern may not have a clear path forward.

Resolution of Ethical Concerns

In many situations, an engineer may seek advice from a colleague, supervisor, or manager when faced with an ethical concern. Different viewpoints can help illuminate aspects of the situation that may not be immediately apparent. In most cases, discussion resolves the concern; however, exceptions do occur. Some ethical issues have no single clear solution, yet they may offer multiple possible courses of action, some more appropriate than others.

Given the circumstances, the objective is to reach a reasonable, ethical, and fair resolution that considers the perspectives and interests of all parties involved. In this process, a degree of compromise may be acceptable. Any proposed course of action must comply with applicable laws, professional obligations, and accepted ethical standards. The examples that follow illustrate such situations and may also serve as scenarios for further discussion in a group setting.

1. Professional Obligations

Professional engineering societies and other authorities consider responsibilities to employers and confidentiality considerations that would otherwise prevent an engineer from acting ethically and in the public interest to be exceptionally serious. All engineering societies, including the AIAA, have ethics review boards. They may also have legal implications through the courts and aviation certification authorities, such as the FAA or EASA. Such issues can have severe repercussions for both employers and employees.

For example, a breach of the Federal Aviation Regulations (FARs) may result in legal consequences and/or civil penalties, depending on the nature and severity of the violation. For pilots and other FAA-certified individuals, this can result in license suspension or revocation. For organizations, a serious breach of the FARs could result in the temporary or permanent revocation of operating certifications.

2. Use of AI Tools

An engineer uses an artificial intelligence (AI) tool, such as ChatGPT, to help draft a journal paper, for example, by improving clarity, organization, or grammar. The technical ideas, analyses, data, and conclusions are the engineer’s own work. Ethical questions may arise regarding the appropriate use of AI in scholarly writing, including transparency, authorship, and compliance with journal policies governing AI-assisted content.

Consistent with the AIAA Code of Ethics, the engineer must act with honesty and integrity, retain full responsibility for all technical content, and avoid misrepresenting authorship or originality. Ethical use of AI requires compliance with journal and institutional requirements, including, where required, disclosure and limiting AI assistance to roles that do not substitute for the engineer’s professional judgment or technical contribution. The appropriate course of action is not to stop using AI tools, but rather to maintain transparency, accountability, and professional responsibility.

3. Unethical Employers

An employee may discover they work for an unethical employer, possibly one with ongoing legal issues. Employees should be especially vigilant to ensure they are not implicated in their employer’s dishonest or illegal behavior. Employers have many incentives to refute accusations of unethical or criminal misconduct made against them by employees or others.

While workplace intimidation or bullying by employers is unethical and may be unlawful depending on the conduct and circumstances, it still occurs. Unfortunately, a toxic or dictatorial corporate culture is the primary driver of employee attrition, creating an unhealthy environment for everyone. Some employees may choose to “walk away” and resign from organizations facing ethical dilemmas or wrongdoing rather than stay and potentially face professional, legal, or reputational consequences.

4. Whistleblowing

Whistleblowing is often considered after internal reporting channels have been assessed, but urgent safety threats or legal requirements may justify immediate external reporting. Still, based on legal case history, it is not uncommon for an employee to take legal or other action against their organization if it exhibits poor judgment, engages in questionable conduct, uses unsafe processes, or engages in illegal activity. For example, misleading corporate statements may become illegal when they constitute fraud, securities violations, obstruction, false statements to regulators, or other legally recognized misconduct.

In the U.S., under federal and state laws, employees who report misconduct may have anti-retaliation protections under specific federal or state laws, but the scope, procedures, and deadlines vary by jurisdiction and subject matter. In many situations, internal reporting channels may be appropriate before external reporting, but urgent safety threats, legal requirements, or applicable whistleblower protections may justify or require prompt reporting to an external authority. Employees considering such action may seek sound legal advice to understand the available reporting channels, protections, procedures, and applicable deadlines. Various factors, including personal values and the risk of future unemployment, can influence the decision to be a whistleblower.

Consequences of Ethical Misconduct

Professional engineering societies, such as AIAA, have ethics review procedures and may impose society-level sanctions for serious ethical violations by individuals, including suspension or expulsion. Professional licenses, certifications, and employment consequences are handled separately by the relevant licensing boards, certification authorities, employers, or courts. When engineering decisions affect public safety or cause injury or loss of life, the consequences can extend beyond professional discipline to civil or criminal proceedings. Engineers also have an ethical responsibility to raise concerns when accepted or sound engineering practices are being compromised, particularly when public safety is at risk.

Prominent examples include the ethical misconduct scandals at Volkswagen involving vehicle emissions controls and at Boeing Commercial Aircraft involving the flight-control system associated with two fatal 737 MAX crashes and the loss of 346 lives. Investigations and analyses of both cases identified combinations of organizational, regulatory, communication, engineering, and commercial pressures as contributing factors. Boeing and Volkswagen subsequently faced criminal prosecution and billion-dollar financial penalties in the U.S. justice system. Of particular concern for aviation was the finding that “Misleading statements, half-truths, and omissions communicated by Boeing employees to the FAA impeded the government’s ability to ensure the safety of the flying public.” The consequences extended beyond legal penalties to substantial harm to the organizations, their employees, the engineering profession, and public confidence.

These cases also demonstrate how organizational culture can influence engineering judgment. A culture that places excessive emphasis on cost, schedule, or commercial performance at the expense of ethical conduct and public safety can create conditions that make poor engineering decisions more likely. Attempts to discredit, threaten, or punish individuals who raise legitimate safety or ethical concerns can compound the problem. They may also be unlawful when they constitute prohibited retaliation, discrimination, threats, obstruction, or similar conduct. At the same time, an engineer’s ethical responsibilities do not eliminate cost and schedule considerations. Rather, those factors must be balanced against the overriding obligations of technical integrity, safety, and professional responsibility.

The professional, legal, and financial consequences arising from such failures can persist for many years, even when individuals or organizations are ultimately absolved of particular criminal allegations. Lawsuits, regulatory action, reputational damage, loss of public confidence, and reduced competitiveness can impose lasting costs. While major engineering failures often lead to calls for reform, scholars have argued that successive generations of engineers repeatedly encounter similar ethical lessons. Preventing recurrence requires more than new procedures after a failure. It requires sustained ethical leadership by management, effective organizational safeguards, and continued education by corporations, engineering societies, and universities so engineers are prepared and supported when they must make difficult professional judgments.

Ethics for Students

Students must strive to adhere to academic ethics at all times. Academic institutions, such as colleges and universities, aim to foster a healthy and ethically responsible learning environment. Students must follow the institution’s principles and policies to maintain its integrity and accreditation. Academic integrity is central to student ethical conduct, and all students must actively participate in maintaining and fostering it; unus malus multos corrumpit.^[2]

Academic integrity and ethical conduct are essential in all assignments, not just those for credit, including homework, exams, laboratory reports, projects, and presentations. Students must answer truthfully and represent their work without cheating or misrepresentation. In group activities, the entire group is held to the same standard. Students who fail to adhere to academic integrity standards can expect consequences, including sanctions. For example, a minor infraction may result in a failing grade on the assignment, while severe or repeated violations may lead to expulsion from the institution.

Plagiarism

Plagiarism is unethical conduct and a violation of academic integrity. It involves presenting someone else’s writings or other work as one’s own or using content or work products without citing or crediting the source. An example of plagiarism is copying and pasting sentences, paragraphs, or other content and submitting it as one’s own. Closely rewording (paraphrasing) content found from different sources, such as changing or adding a word here or there, especially without citation, is also a form of plagiarism.

Self-plagiarism is also unethical and a violation of academic integrity. One example is using duplicate content (e.g., previously graded homework or an essay) to satisfy the requirements of another course. This type of academic integrity violation also applies to repeating the same course, even if a different instructor teaches it. Ethically, students must not resubmit prior work for new credit without permission and any required disclosure. Taking the chance that nobody will notice is always unwise.

Avoiding Cheating

Cheating is always unethical, not only in academic settings. Cheating, or even the perception of cheating, can be avoided by completing one’s assignments responsibly and ethically, including homework and exams. Tasks are usually completed individually unless a group activity has been assigned. A student should never copy another student’s work or misrepresent it as their own.

Examples of cheating include copying another student’s answers on homework or using unauthorized resources during an exam. Such unauthorized resources may include unapproved electronic devices such as cell phones, solution manuals, tutoring services, texting, or any other items explicitly prohibited by the instructor in the course policies.

Some other examples of cheating may include:

• Facilitating or aiding and abetting the cheating efforts of other students.
• Providing assistance that exceeds the assignment rules or misrepresents authorship, including writing or substantially rewriting another student’s submission.
• Copying or even attempting to copy answers from another student during an exam.
• Having, without the instructor’s permission, any exams or other materials belonging to faculty, staff, or another student in their possession.
• Giving another student answers to previous exam questions or other assignments unless the instructor or other faculty has expressly authorized the release of the answers.

Copyright Matters

All engineers must be familiar with copyright issues, copyright law, and their practical implications for day-to-day practices, work products, and other activities. Copyright matters are covered under U.S. and international law. In the U.S., copyright law is published by the Copyright Office at https://www.copyright.gov/title17/. Copyright protects the creators of original works, such as reports, books, photographs, graphics, diagrams, figures, videos, music, and designs. Remember that copyright law also applies to digital media and to the expressive elements of software, such as source code and object code. However, copyright does not protect the underlying ideas, algorithms, methods, or functional behavior embodied in the software.

What Does Copyright Mean?

Copyright protection means that if someone creates an original work product, they own the copyright to it. An original work means any authorship in a tangible medium of expression. Although exceptions exist, this rule generally holds. Exceptions may include “work made for hire.” In general, work an employee creates as part of their job may belong to the employer. For work created by consultants or independent contractors, ownership depends on the contract or written agreement. Therefore, engineers should understand the ownership terms before creating reports, drawings, software, data products, or other technical materials for another party. However, shared authorship is generally considered standard practice. Nevertheless, a consultant may not have publication rights to work produced under a work-for-hire agreement.

Copyright also protects both published and unpublished works. That is, a work on tangible media need not be formally published to be protected by copyright law. It is a fallacy that the copyright symbol must be used and attached to a work to copyright it. Nevertheless, if used, a copyright notice should contain the word “copyright” or a “c” in a circle , the date of publication, and the name of the author or owner of the work. Copyright protection exists automatically when an original work of authorship is fixed in a tangible medium of expression, whether physical or electronic. Copyright also applies to most, if not all, college and university course materials, such as professors’ course packets, course slides, homework problems, exam questions, and solutions.

Copyright law cannot protect intangible assets, such as ideas. Just because someone has a good idea does not mean copyright law immediately protects it. Writing or recording an idea may create copyright protection in the original text, drawing, or other expression, but not in the underlying idea, method, system, procedure, principle, or discovery. The protected expression must contain sufficient original authorship. Scientific and historical facts, accepted theories, established methods and equations, and content considered “common knowledge” are generally not protected under copyright law.

Avoiding Copyright Infringement

It should always be assumed that copyright applies to all work products, published or otherwise. Copyright rules and laws can be complicated. For many individually authored works created on or after January 1, 1978, copyright generally lasts for the author’s lifetime plus 70 years. For works made for hire, anonymous works, and pseudonymous works, the term is generally 95 years from first publication or 120 years from creation, whichever expires first. However, copyrighted content can be published and used in several categories, so it’s important to ensure full compliance with copyright laws and protocols.

Public Domain

When copyright expires, the work enters the public domain, meaning anyone can use it in any form they choose, regardless of who holds the rights. However, they still cannot claim ownership of the work. If known, proper attribution is an ethical responsibility, even if it is not legally required. All works published in the United States before January 1, 1931, are in the public domain. For many U.S. works first published from 1929 through 1977, the copyright term is generally 95 years from publication, although notice, renewal, foreign-work status, and other rules can affect the result.

U.S. Government publications are generally in the public domain, at least in the U.S., when federal employees prepare them as part of their official duties. Work done under a U.S. Government contract (e.g., research at a university) typically belongs to the principal researcher, students, and/or the university. Ownership of a thesis, dissertation, or research output may depend on authorship, institutional policy, employment status, sponsored-research agreements, joint authorship, confidentiality, and other contractual terms. Raw facts and data are generally not protected by copyright, although original text, figures, databases, and the selection and arrangement of these elements may be protected.

Some other types of materials may already be in the public domain, but this is rare. Materials found on Wikipedia, Wikimedia, and similar platforms are generally not in the public domain, even when the copyright holder declares them open source, such as under a Creative Commons license. Creative Commons (CC) licenses promote collaboration, sharing, and creativity while respecting the original creators’ copyright. Still, users must follow the conditions of the specific license, including attribution when required. A CC dedication, for example, does not require attribution.

Fair Use

What is known as “fair use” is an exception to the restrictions imposed by copyright law. Fair use is a case-specific legal doctrine that can apply in both commercial and noncommercial settings. An educational or nonprofit purpose may favor fair use, but it does not automatically establish it. Fair use generally does not extend to reproducing entire documents or other complete works, but it does allow brief excerpts. Some academic institutions use internal practical guidelines for limited classroom use, typically 10%, but no fixed percentage or number of figures guarantees fair use. Fair use depends on the statutory factors, including the purpose and character of the use, the nature of the copyrighted work, the amount used, and the effect on the potential market.

The underlying rationale of “fair use” for academic purposes is that the education of students will benefit by including some parts of the copyrighted material. Market effect is only one statutory fair-use factor. Attribution should be provided when appropriate, but attribution alone does not authorize an otherwise infringing use. Permission, an applicable license, fair use, the public domain, or another legal exception must provide the authorization. Licensing terms and fees vary by copyright owner and type of use. Exceptions may include specific organizations or copyright clearing centers that require payment of copyright fees before any published work may be used in another work.

Creative Commons

Creative Commons is a non-profit organization that provides free, easy-to-use legal tools for creators and users of creative work. Creative Commons licenses let creators share their work with others while retaining certain rights under copyright law. There are six different Creative Commons licenses, each with its own set of conditions. These conditions range from requiring attribution to the original creator to allowing commercial use of the work. By using a Creative Commons (CC) license, creators can ensure their work is shared and used freely in ways that align with their goals and values.

Individuals, organizations, and governments worldwide have widely adopted Creative Commons licenses. Professors, artists, musicians, writers, teachers, and scientists, among others, use them to share their work and promote learning, collaboration, and innovation. Many online platforms support Creative Commons licenses, making it easier to share work and helping users find and use it legally. For example, this e-textbook is available under a Creative Commons (CC) non-commercial, non-derivative license. However, it should be noted that a CC license sits “on top of” the copyright and does not replace it; the copyright symbol (if used) indicates the copyright holder, and the CC statement indicates the public usage rights the copyright holder grants. Remember that copyright law still applies to work published under a CC license, and that the terms an author uses to share their work should always be respected, as this is both a legal requirement and an ethical obligation.

Gaining Permissions

Using work products from other sources should be done with proper permission when required by law. Works in the public domain generally do not require permission, although proper attribution remains an ethical responsibility when the source is known. The copyright owner controls the exclusive rights granted by law, subject to licenses, assignments, contracts, fair use, the public domain, and other statutory limitations. Most authors are pleased that their work is of use and helps others. Permission decisions vary by owner, work, and proposed use.

Gaining permission from the author of a copyrighted work may require a request by letter or email, but the request and any permissions (if obtained) should always be in writing. Work published under a Creative Commons license should always be given the appropriate attribution, even though explicit consent from the author to use the work need not be obtained. Images in this e-textbook may be used only according to the license or permission applicable to each image. Attribution is required when the governing license requires it.

Penalties for Copyright Infringement

“Copyright infringement is the act of exercising, without permission or legal authority, one or more of the exclusive rights granted to the copyright owner under section 106 of the Copyright Act (Title 17 of the U.S. Code). These rights include the right to reproduce or distribute a copyrighted work. In file-sharing, downloading, or uploading substantial parts of a copyrighted work without authority constitutes an infringement.”

Therefore, copyright infringement means using someone’s work without permission or in ways that do not align with the copyright holder’s rights. Copyright infringement may result in civil liability and, in qualifying willful cases, criminal penalties. It is illogical for an engineer, employer, student, or other individual to risk sanctions or penalties for improper use of content or potential copyright violations. Permission is unnecessary when an applicable license, fair use, the public domain, or another legal exception authorizes the use. Copyright infringement can lead to substantial civil liability and, in qualifying willful cases, criminal penalties.

Those liable for civil copyright infringement may be ordered to pay actual or statutory damages for each infringed work. In addition, for willful infringement, a court may award statutory damages of up to $150,000 per infringed work. A court can also assess costs and attorneys’ fees. For more information, see the U.S. Copyright Office’s website at www.copyright.gov, especially their FAQs at www.copyright.gov/help/faq. Students are not exempt from the law, and copyright infringements they commit carry the same legal consequences as those committed by anyone else. Students who violate copyright law may also be charged with violating their college or university honor code (e.g., for fraud) and risk sanctions such as probation, suspension, or expulsion.

What is the DMCA?

The Digital Millennium Copyright Act (DMCA) is a 1998 amendment to U.S. copyright law. This law applies to copyrighted material uploaded to the internet in digital form. The DMCA is most likely to become applicable if a person:

• Downloads copyrighted content from the internet and publishes it elsewhere without the copyright owner’s permission,
• Uploads copyrighted content to a website or other online platform without the copyright owner’s permission.
• Digitally shares any copyrighted work without the copyright owner’s permission.
• Shares copyrighted software or other copyrighted materials, e.g., person-to-person or peer-to-peer (P2P) sharing of software or software piracy.

Downloading or sharing may be lawful when authorized by the copyright owner, an applicable license, fair use, the public domain, or another legal exception. Under the DMCA, the copyright owner may request that the online infringement be rectified. Note that, as with other aspects of U.S. copyright law, the DMCA outlines both civil and criminal penalties for copyright violations.

For example, suppose a copyright holder files a DMCA Takedown Notice for a potential copyright violation on the internet or other online platforms. In that case, a qualifying service provider seeking section 512 safe harbor protection must act expeditiously to remove or restrict access to the identified material upon receipt of a compliant notice and must notify the uploader. The uploader may submit a compliant counter-notice when the removal resulted from a mistake or misidentification. Unless the claimant files a court action, the provider generally restores the material after the statutory waiting period has elapsed. In addition, legal resolution of any copyright infringement may result in civil and criminal penalties for the violator. Such situations are relatively rare, but they do happen.

Most commercial software, such as MATLAB, is copyrighted and governed by license terms as well as by its developers’ intellectual property rights. Unauthorized software use may expose an organization and responsible individuals to contractual, copyright, audit, cybersecurity, and financial consequences. Software vendors and copyright holders may take legal action against individuals or organizations to protect their intellectual property and recover damages. Many industries face regulatory and auditing requirements, including software licensing compliance; non-compliance can lead to significant legal and financial consequences.

Ethical Scenarios to Consider

Learning more about professional ethics and proper ethical conduct can be achieved by considering some hypothetical ethical scenarios. These provide concrete examples of dilemmas or situations in which ethical principles come into play, enabling one to analyze, discuss, and reflect on the various factors involved. By engaging with ethical scenarios, individuals can develop their ethical reasoning skills, gain a deeper understanding of different perspectives, and cultivate a more nuanced appreciation for the complexities of ethical decision-making. An active approach to learning ethics helps students and others apply ethical principles to situations they may encounter in professional practice.

Using ChatGPT

ChatGPT is an artificial intelligence service that can use different models and tools. It can assist with explanation, drafting, coding, analysis, and problem-solving, but its outputs may be incomplete, incorrect, biased, or unsuitable for a specific professional context. For students and practicing engineers, ChatGPT can be a valuable tool for a range of tasks and for enhancing the learning experience. However, using it effectively, responsibly, and ethically, and understanding its limitations, is essential. The following principles summarize responsible use:

1. Research and learning: ChatGPT can help you find information and understand complex topics by providing explanations and examples. Use it to clarify concepts, gather different perspectives, and explore ideas. However, always cross-verify the information you receive and consult authoritative sources to ensure its accuracy. ChatGPT has many areas for improvement in engineering topics.
2. Writing assistance: ChatGPT can help generate ideas, overcome writer’s block, and get feedback on your writing. It can suggest alternative phrases and sentence structures or provide examples. However, remember that it is still an AI model, not a substitute for your critical thinking and creativity. Take the suggestions as starting points and tailor them to your writing style.
3. Language practice: Conversing with ChatGPT can help improve your language skills. You can practice grammar and vocabulary and even engage in simulated discussions on various topics.
4. Problem-solving and programming: ChatGPT can help you understand programming concepts, debug code, and provide general problem-solving guidance. It can suggest possible solutions or help you identify errors. However, be cautious when relying on ChatGPT for programming tasks, as it may not always produce correct or optimized code.
5. Ethical considerations: ChatGPT is a machine-learning model trained on vast amounts of data. While it strives to provide helpful information, it may sometimes generate biased or incorrect responses. Be critical of the information it provides and assess its reliability. Avoid using ChatGPT for sensitive or personal topics that require human expertise or empathy.
6. Academic integrity: It is important to remember that different universities use AI tools in different ways. Some instructors will encourage you to use ChatGPT as a resource, while others may ban it altogether. It is essential to consult your university’s academic integrity policy regarding the use of AI tools.
7. Privacy and security: When using ChatGPT, be mindful of the information you share. Avoid sharing personal or sensitive data. Do not enter confidential, proprietary, export-controlled, personal, or sensitive information unless its use is authorized and consistent with applicable organizational policies and selected privacy settings.
8. Supplement learning: Consider ChatGPT a supplementary tool, not a replacement for traditional learning resources, textbooks, or professors. Use it to complement your studies, clarify doubts, and explore new ideas. Always maintain a balanced approach to ensure comprehensive learning.

Users remain responsible for verifying outputs, protecting confidential information, complying with applicable laws and policies, and ensuring that AI assistance does not misrepresent authorship or professional judgment. Remember that while ChatGPT can assist, taking an active role in one’s education and professional development is essential. To this end, “it is important to engage in critical thinking, seek diverse perspectives, consult reliable sources, speak with professors, and actively participate in one’s own learning. It is important to check the academic institution’s policies before using ChatGPT to help with assignments.

Summary & Closure

The field of aerospace engineering has ethical and legal responsibilities that all engineers must uphold. The profession has established these ethical principles over many decades. They establish an aerospace engineer’s standing among their clients, employers, the profession as a whole, and the public at large. In addition, ethical policies may be part of regulatory law in some countries or jurisdictions, so that ethical violations could result in civil or criminal penalties.

Copyright law generally covers most engineering work products, and ownership typically belongs to the creator. However, in some cases, if the work is performed for another party (e.g., an employer), it may be considered a “work for hire,” and the employer may own the copyright. The bottom line is that people cannot do whatever they want with someone else’s work, and everyone should follow the law and seek permission before using others’ work. Copyright also applies to most online digital material, i.e., anything found on and/or used from the internet. Exceptions include works declared in the public domain, most U.S. government works prepared by federal employees as part of their official duties, and U.S. works whose copyright term has expired.

Use copyrighted material only when authorized by permission, an applicable license, fair use, the public domain, or another legal exception. Academic purpose may favor fair use in some circumstances, but it does not automatically establish fair use. Fair use can also apply in criticism, comment, news reporting, parody, software-related uses, and other commercial or noncommercial contexts. Professors and other instructors use content from various sources to enrich their students’ educational experience, and much of it may be protected by fair use. This is one reason why students should not distribute any course materials beyond their personal use.

In many cases, this can lead to legal consequences, such as a lawsuit for copyright infringement outside the scope of fair use, and that is never a desirable position to be in. As a student, it is essential to understand and comply with copyright laws, as they apply to everyone. Properly attributing work shows respect for the creators and demonstrates an ethical and legal responsibility.
