I was thinking about this earlier today.
The thing that always used to bug me with most of the instruction I've received over the years.....it's hard for them to stop 'teaching'. At some point, later in the training I think it would be great to ask them to keep their mouth shut...just be there to stop any major screw-ups...but otherwise let you figure out your own way..and more importantly build confidence.
[
EDIT - The following advice assumes you are pretty far along in your training and actually DO know what you are doing and only need the chance to prove it uninterrupted.]
Want to know the easiest and fastest way to get your instructor to shut their mouth and let you fly?
Do not let them get a word in edgewise.
I finally cracked this code during instrument training. It
always seemed I was behind the airplane and I was getting very frustrated. One day I realized the reason I was behind was because every time I was about to reach for the flaps, gear, OBS, whatever... my instructor would prompt me and instead of finishing my thought and completing the action, I would stop to listen to what they were saying (thinking they were correcting me) and thereby actually getting behind the aircraft.
I fixed this by continually talking through the entire flight. I would enunciate everything I was doing and if there was nothing obvious to be done (during cruise, for example) I would be enunciating my instrument scan, what I was thinking of doing five minutes from now, ETA to destination... Whatever it took to keep them from talking.
This lets the CFI know that you
ARE thinking ahead of the airplane and that you really do understand what is happening.
This technique worked well for my follow-on ME and CFI/CFII ratings as well.
As an instructor myself now, it does my heart good the day I finally get this idea drilled into my students. When they are talking their way through the flight and telling me what they are thinking about well in advance of it actually happening I know they are actually understanding and applying their learning.
Of course there ARE times when the CFI needs to talk for whatever reason, but in my experience as long as you keep talking and allow them to interrupt when necessary to correct you or teach you something new, as long as you are talking (and not making mistakes without catching them
*) they will mostly remain quiet.
*This is the biggest area where talking out loud helps. "Oh-oh... My altitude has slipped a little... Correcting!" for example...
