You can actually have a full first flight lesson for far less than the usual cost. The lesson consists of learning how to conduct a preflight inspection of the plane. YOU will then start the engine, taxi the plane to the runway, perform the takeoff (with the instructor's assistance if needed), fly the plane and learn about airspeed and altitude control, and fly the traffic pattern upon return to the airport. The lesson will consist of at least two hours of instruction and one hour of flight.
At our usual rates, the cost of this lesson would be at least $210.
