The maneuver is as good as the pilot and yes, it has been done for ages in C182s. RickT86 or one of the other former jump pilots will tell you. You do this maneuver 30 times a day from 14k down to 1k for years at a time, not a stressed rivet in sight. I worry about pilots who have no feeling for things more than those who do and fly using their experience, knowledge. common sense and intuition. Fly like you love it and know what you are doing. No problems that way, none at all. What are the g's telling you? What are the airframe sounds telling you? How do the flight controls react? How would you feel if you were the airplane right now? What does the science tell you? Does the science agree with your experience? Why or why not? That is the way to think about any performance maneuver. Never fly mechanically.
