Learning Aero's is not just about learning the manouvers, like most things in aviation the basics are not hard but you need to know what to do if it goes wrong. This is the main thing i want a student to know before I will let them off to practice Aero's by themself. Another problem is you may not realise you are overreving the engine - this is a very common problem with people new to Aero's (Hands up Aero instructors who never have to touch the throttle on the first few Aero's sessions) and can prove very expensive at the least.
Circuit Basher - A HEALTHY disrespect for the rules involves Knowing what you are doing, THEN doing something you can get away with but perhaps shouldn't!
