There are schools out there that teach to power out of a fully developed stall holding attitude.
Yeah, I had a fresh minted CPL try that in a Rans Coyote when converting to type. Interesting.......
But even for steep turns the clearing turns are taught
So, you do a turn to see if it is OK to do a turn? Surely if it is a collision avoidance exercise you need to turn away from the hazard smartish? Of course, if it is a co-ordination exercise that is a different matter. 45 degrees isn't really a steep turn, though, is it?
