ADI (Attitude Direction Indicator) 3D uses internal sensors and mimics the behavior of an aircraft ADI. It's designed for educational purposes only (ie., student pilots, science students, navigators or anyone curious of Euler angles). ADI 3D displays its orientation using unique 3D graphics. One graphic has a similar look to a traditional aircraft ADI. The other graphic shows the perspective from inside the ADI sphere. The use of 3D graphics makes ADI 3D different from typical aircraft instrumentation.

Note to pilots: the app is not intended or designed as a functioning aircraft ADI. Although the app may appear to function properly, there will be times when the orientation is inaccurate. This may occur during a prolonged turning maneuver or at other times. API 3D is an educational app.
