Based on 50 flights, 25 hours in 2 seater glider with instructor and solo within one year of membership, an average training flight would be 7 minutes on aerotow behind our Piper Pawnee, taking you to an altitude of 2,000 ft (600 meter). If you spent 30 minutes flying in a DG 505 during training, you would be charged $36.82 for the aerotow and $30.00 for the glider.
