4500ft for stalling? You are pulling my leg?
No. Stalls at 3,200 ft for recovery by 3,000 ft. Not unreasonable, especially when demonstrating a wing drop / incipient spin. As you know, VFR requires 1,000 ft clearance from cloud above 3,000 ft.
I am quite happy to do stalls down to the 2,000 agl limit in our flying orders, but the additional height is worth having in some circumstances. A 1 turn spin in the T67m I sometimes use will burn 1,100 ft, so if there is any possibility of a spin I would prefer to be a bit higher.
If I can only achieve that additional height by switching to IFR, why wouldn't I? What is the problem?
