I am absolutely astounded that you can get a licence in the UK that entitles you to land in a confined area, without ever having gone into one in a training environment.
Isn't that one of the big reasons we fly these things, to enable us to go into places where fixed wing can't?
What about if you train for a CPL? Does the CAA allow you to do the "Real McCoy" then?
By the way, when I used to do ab-initio training, you would obviously get the student to first fly the required steep approach and vertical take off profiles at the airport until they had them down pat. Then do exactly the same thing in amongst the trees and they would ALWAYS make a pizza of it in the beginning. I used to tell them that the aircraft didn't know that the obstacles were there, and there was no difference from the aircraft's point of view to what we'd just done at the airport, but it goes to show just how much the nerves and a new environment can interfere with basic handling and decision making.
