ADI (Attitude Direction Indicator) EFIS uses internal sensors and mimics the behavior of an aircraft ADI and compass. The app is designed for educational purposes only (ie., student pilots, science students, navigators or anyone curious of Euler angles). ADI EFIS displays its orientation using a traditional EFIS display. 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 or heading is inaccurate. This may occur during a prolonged turning maneuver or at other times. API EFIS is an educational app.
