Flying club
I'm a member of a flying club here in Switzerland, and it works really well. The reason it works well is that there is one guy that is the airport manager, head instructor, and the chief pilot on the field who runs things with an iron fist covered in velvet.
He's a great instructor, and before anyone takes out any of the five aircraft, he spends
a lot of time with them doing touch and goes. Also, to get checked out in any of the aircraft, you're looking at a good 3 hours of transition training, including flight under simulated full load conditions.
Rules here are pretty strict on maintenance. These aircraft are in better shape than most of the privately owned planes on the field. I've never seen a single drop of oil under any of them. They were all bought new, most in the 70s, and the entry trainer, a piper warrior, has over 15,000 hours. I have no idea how many engines have been installed in that aircraft. Here's a picture of that little gem on the apron:
My point is that aero clubs can work, and like most successful organizations, it takes one or more driving forces to make it happen.
