I have to agree with Chuck & Big pistons about the standard of training, the worst is in the places with the instructors dressed up with enough gold braid to put a South American general to shame. You know the places I am talking about 5 mile stablised approaches in a 152 !
The best instruction in the UK comes from the places were the instructor is dressed in jeans & tee shirt an he is not dreaming of flying a 747.
