Flight test

Flight tests are tests that pilots do to make sure that airplanes are ready and safe to fly. Flight tests involve the pilot checking to make sure that the engine, instruments, and controls all work properly. They also check if the airplane can safely take off, fly, and land. Doing a flight test before each flight is important to make sure that everything is working properly and that the plane is safe to fly.
