Using a Pressbooks Webbook
Welcome! This ebook has been created using Pressbooks. If this is your first time using a Pressbooks webbook, this chapter will provide some basic information on navigation, download options, and special features in this particular ebook.
Basic Navigation
There are multiple ways to navigate through a webbook, either from the main title page or within the webbook. You do not have to register or have login credentials to use a webbook! 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 into any section or chapter by clicking on the chapter or section title. Some chapters may have a “lock symbol” next to them, indicating they are not publicly visible on the internet or password-protected; e.g., they may be designated for class use only. If you think you should have access to the content and do not, then you should contact Dr. J. Gordon Leishman for more information.

Once inside a webbook, you have a few other options for navigation. You can go back to the title page by selecting the ebook’s title or see all contents of the book using the “Contents” drop-down in the upper left corner. Like on the title page, clicking on any chapter or section title 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 in the ebook (like reading a physical book in order). For students taking AE201 at ERAU, sections and subsections with the header in RED are separate from the formal course material from an examination perspective. However, all students should still pay attention to the content because it will likely give a broadened 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 see what formats are currently available for download. In addition, download options will be available in a drop-down under the ebook’s cover image. So that you know, 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 link to the online-only content.
Search Feature
Above the ebook’s title, there will be a search box with a magnifying glass symbol or a menu button that looks like three parallel lines in the upper right of the webbook. The search function will be available if you open the drop-down menu. This then gives a full-text search of the ebook and will return 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.
