flight hours vs hobbs hours and repairs ?
I just would like to hear some more opinions on the following facts I heard yesterday from a friend, who runs a flight school and charter business.
He changed his business from charging per Hobbs hours to real flight time about a year ago and now claims that engine repair costs for the otherwise unchanged fleet has gone down 30%. He is running 172, 182, PA24 and PA28 with about one third in training and two third in charter.
First reason in my mind was that running on Hobbs tend to let people hurry to take off with less warm up, but can this effect be such big?
