... Just STFU already and let the student who knows what to do and has already mastered the skill just do his thing and do it well.... I also teach GA's version of sterile cockpit. But boy am I one of the worst violators of this.... Maybe I need a placard on my side that says, "Overtalking and over teaching prohibited" Learning to be a CFI, I had the problem of slowly going quiet as I did the maneuver. My instructor would friendly poke fun at me saying I was like the talking toys with the string you pulled, but I was out of string. Who knew with students, I would develop the opposite habit. Private pilot license might be "a license to learn". But with a CFI, it's a whole other universe. I feel like I'm learning what I already know all over again. And enjoying every loving minute of it.
