Welcome to the world of electronic textbooks, often referred to as eBooks, e-textbooks, or webbooks. This particular eBook has been created using the Pressbooks platform, which fully supports the Open Educational Resources (OER) endeavor and Creative Commons (CC) licensing. If this is your first time using a Pressbooks eBook, this chapter provides basic information on navigation, download options, and special features specific to this eBook.

An Open Educational Resources (OER) endeavor is a coordinated effort to develop, share, and promote the use of freely accessible, openly licensed educational materials that can be used, adapted, and redistributed by anyone. These initiatives aim to reduce student costs, improve access to quality learning, and support faculty in customizing content to their pedagogical needs. OER endeavors typically involve collaboration among educators, institutions, and libraries, and are supported by platforms like Pressbooks, OpenStax, and OER Commons. By enabling legal reuse and adaptation through open licenses (such as Creative Commons), OER efforts foster equity, innovation, and sustainability in education.

Basic Navigation

There are multiple ways to navigate through an eBook, either from the main title page or within the eBook itself. You don’t have to register or have login credentials to use an eBook! Starting from the title page, you can read the eBook on page 1 using the “Read Book” button. This is like opening a physical book to the first page! You can also scroll down to see all the eBook’s contents and go directly to any section or chapter by clicking on the chapter or section title. Some chapters may have a “lock symbol” next to them, indicating that they are not publicly visible on the internet or password-protected; for example, they may be designated for use by ERAU classes only. If you are an ERAU student and think you should have access to the content but do not, please contact Dr. J. Gordon Leishman for more information on how to proceed or to gain access.

Once inside an eBook, you have a few other options for navigation. You can return to the title page by selecting the eBook’s title or see all book contents using the “Contents” drop-down in the upper left corner. For example, clicking on any chapter or section title on the title page will take you to that part of the eBook. Finally, you can use the navigation bar at the bottom of the page to move forward and backward through the eBook (similar to reading a physical book in sequence).

Sections with headers or subheads in red are suitable for more advanced students. For students taking AE201 at ERAU, these parts are separate from the formal course material and from an examination perspective. However, all students should still pay attention to the content, as it will likely provide a broader perspective on the course material.

Download Options

This eBook may be available to download in various formats, such as a .pdf for offline reading or other uses. You can return to the eBook’s title page to view the available download formats. Additionally, download options will be available in a drop-down menu under the eBook’s cover image. Some interactive features are only visible in web-enabled versions of this eBook. Therefore, components removed in offline formats should be replaced with a warning and a link to the online-only content.

Search Feature

Above the eBook’s title, a search box with a magnifying glass symbol or a menu button resembling three parallel lines will be located in the upper right corner of the eBook. The search function will be available if you open the drop-down menu. This then provides a full-text search of the eBook, returning the chapters where the word appears. Put the term in quotations if you need to find a specific phrase. For example, “lift capability” will search for the phrase rather than the words “lift” and “capability” separately.

Special Features in this eBook
