You must be what 20degs nose up with power off when you start to recover. Then reducing that down to nose on the horizon is reducing the AoA by at least 10-15 degrees
CJ4 Stipulates 5 degrees so 15 degrees nose up on your calcs?
I really think its easy at home on the computer to discuss theory different to try it practically.
The Idiot FAA examiner method gave a minimal height loss. My semi conventional recovery lost a lot.
At 400 feet he would have recovered I would have hit the ground.
