I'll try to make this question a little more manageable by applying the following constraints, though of course all answers would be welcome:
- By "General Aviation / Training" aircraft, I'm talking primarily about normal SEP's of the kind that we see daily and would require no more than a check-ride before hiring. No experimentals, warbirds, super rare aircraft etc - though MEP's and Complex Aircraft would count.
- I'm ignoring low level maneuvers. We all know a stall at 100ft is going to be tricky, though on the other hand, if something is going to require 5000' at a minimum to recover from then that's going to be fatal in most cases.
- Let's ignore mechanical and airframe failures that occur prior to the incident.
- I'm assuming Weight & Balance are within the normal category of the POH (As opposed to utility or aerobatic).
Beyond that, the question is what it says on the tin. Is there anything stupid that I can do as a Pilot in a Single Engined Piston GA aircraft that I simply won't be able to recover from, even with a few thousand feet to do so?
