I notice that unlike many posters you advocate rolling into the bank then applying full power. Before your post I thought I was missing something.
A max rate turn would be the shortest time to execute 360, or what ever change of heading you chose. I think I like your idea of allowing a descent during the turn to achieve this.
Does a canyon turn count as a max rate turn?
Question? Does a max rate turn correspond to a minimum radius turn?
