Aviation has a language all its own; "aviationspeak" if you will. To keep up with the terminology, and the times (you've probably use Web-based Wikipedia), we've developed our own aviation-based directory of terms, Wingipedia. In our first edition, we covered "acrobatics" through "induced drag." Our second installment continues with "Jenny" through "roll." If you'd like to add to our aviation encyclopedia or you think that we've omitted anything, this is the space to add your two cents.
