Detailed Description

General aviation artificial horizon / AH (instrument)

This class allows to draw a general aviation (analogic) artificial horizon (AH). The pitch and roll angles are artificially computed based on the vertical vs. horizontal speeds (pitch) and the rate of turn vs. horizontal speed (roll). It includes the logic that allows to cache the necessary QPixmap(s) required to draw the instrument and avoid to "re-render" it each time it is "refreshed".
