The Beginner’s Guide to Aeronautics (BGA) was created
as a Internet-based “textbook.” The creation of the BGA is a analysis undertaking
to discover using the private laptop and the Web to current academic
supplies to college students, academics, and lifelong learners in a extra interactive
approach than a printed, sure textbook.
As a common rule, the Internet consists of many particular person pages which can be
related, or associated, to at least one one other by way of hyperlinks. The Internet is,
due to this fact, a lot much less structured than a sure e book, through which one web page follows
one other in a particular, numbered sequence. We’ve deliberately organized the
BGA to reflect this unstructured method. Customers can navigate the pages
of the BGA by way of hyperlinks primarily based on their very own curiosity and inquiry.
For individuals who desire extra construction to the data obtainable on the BGA,
we have now organized a substitute for the unstructured approach–a variety of guided
excursions by way of the location. Every tour is organized round a single subject, and
customers transfer from web page to web page by way of the tour by utilizing particular buttons on the
backside of every web page.
Click on to maneuver again to the earlier web page. Click on to maneuver to the subsequent web page. Click on to return to this web page on the finish of every tour.
(Some pages will likely be “crossed” by multiple tour, so it will be significant
to recollect which tour you’re on. If you happen to click on on a hyperlink you’ll go away
the tour; you’ll be able to rejoin the tour by utilizing the browser’s “Again” command.
If you happen to want to abort a tour and return right here, simply click on on the “Guided Excursions” label
positioned above the buttons.
)
All the excursions start and finish on this web page except in any other case famous.
Descriptions of every tour are given below–just click on on the
title of the tour to begin you in your approach. Have enjoyable!
