This trainer is designed to help you practice your basic instrument flying skills. It will give you instructions to fly a heading, altitude and airspeed. Start in the simulator flying North, at 3000ft, at 105kt, ideally somewhere with no terrain nearby. You can then fly your simulator aircraft to the desired parameters. When you are ready, click the "Commence" button to generate your first instruction. The app will allow sufficient time for you to complete your maneuvre before issuing you a different set of instructions.
