Stuck...
FH1100,
I agree totally that it is a fairly high risk procedure, and I also agree that it is very unlikely to happen. I am, however, still in favor of training it as much as possible due to the fact that you learn so much about how to cope with difficult situations and, most importantly, you get a lot of coordination training and learn your aircraft's behavior.
Another good thing to spend a lot of time doing is quickstops. Same there, coordination.
