Oh, give the guy a break! Of course he'll ask his instructor. He's just excited and wants to be as prepared as he can be in advance of turning up for the flight. This is a good thing and shows he has the right attitude to learning.
I know I'm guilty of asking similar questions while I was training, all of which were still run past my instructor, as the 'definitive' source. While I wasn't flying, I wanted to be discussing flying. And where better to do that than here.
Good luck Rob, and keep the questions coming
