Before the flight, your instructor will give your your first ground lesson, followed by your first flight lesson. This counts towards the aeronautical experience required to obtain a pilot certificate.
Expect to spend 45 minutes on the ground portion, followed by a similar amount of time in the aircraft. You will then log the lesson in a logbook (your own, or we can provide you with one).
Finally, your instructor will answer any additional questions you may have about the training process. In total, you will spend around 2 hours at the airport.
