price difference
I had a good look at this price difference too and worked it out that at aerofan you have to fly out to 50 nm to start training due to madrid controlled airspace at aerodynamics its full ILS NDB VOR on take off and landings, price difference is that aerodynamics advertise an ME IR. including ME rating which puts the addtional 1500 quid on it. Aerodynamics are well respected in Spain, France and Germany and have several Euorpeans who fly for them.
