How can I change the aircraft’s heading?

Put two fingers on the map, and rotate them. The aircraft will simply follow the rotation.

What is the trajectory mode?

Press “Trajectory” to switch the app in trajectory mode. Then draw a trajectory with your finger on the map. When you’re done, press play (“>”), the aircraft follows the trajectory and you can observe how the instruments react.

This is possible on iPad only.

What is the quiz mode?

When you press “generate a quiz”, the app will hide the aircraft and randomly move the stations. Use the instruments to find where the aircraft is, and touch this position. If you’re right, the aircraft will appear again. You have only three chances.
