To use the Aero
search feature, type in a keyword or set of keywords (separated
by spaces) into the text box and click on the "Search Aero"
button. The query will retrieve from the Aero web site a
list of articles that contain your keywords. This list is sorted
by relevance. That is to say, if you search for the word "empennage,"
the resulting report will first list articles that contain the greatest
number of references to "empennage."
