First of all, I just copied that from another bulletin board - it wasn't me (read the post).
Secondly, it is a typical situation in the mountains, POH notwithstanding, and a 90 degree snap to the right is not what you want right then. It shouldn't be what you get at *any* time.
When senior test engineers or pilots admit that it was a bigger factor than originally catered for, I would suggest it is something that ought to be fixed, n'est-ce pas?
