HAHAHAHAHA.
So funny! My grandpa used to flight instruct and he put his students in spins while on downwind when they started getting cocky. He said he wouldn't help them recover. He's 87 now, so I guess he and his students lived. Times were different. But one thing stays the same. You've gotta have confidence in the quality of instruction you are providing. That helps me to not grab the controls.
About that hearing thing. Its true, the first thing to go when you're stressed is your ability to hear. Plus anything you do hear is not understood completely as it would be in a classroom. I say the cockpit is a lousy classroom. Thorough pre and post briefing plus student effort at home helps me to be a decent instructor in the cockpit. For every hour of flying we do YOU will put in at least that much on the ground. Saves them hobbs time=saves them money.
Here's my funny story. I volunteered to administer a simulated instrument checkride to the typical "I want an instrument rating NOW, sign my book" student. He told me during preflight that he was so ready, his instrucor is stalling signing him off. (This is like his fourth instructor because he's hunting for the sign off) Told him we were simulating a real instrument flight. Told him his clearance was on request with me, ATC. (all you instructors know this before flight classroom briefing).
Not one chart out not one tinge of hestation and the guy just took off. "OK, lets put the hood on, I've got the flight controls" I say, feeling somewhat suprised. I give him the controls back in a little nose up unusual attitude and recovers nicely. "What altitude are you climbing to and to where and what are you navigating with?" No response- takes out his TERPS and start looking for the local VORTAC. I cut him some slack and remind him of the breifing we agreed to and hooked him up with his clearance. He wrote it on the TERPS. He had the ring binder type NOS charts but no rings so as he wrote he spilled about 3/4 of them on the floor. Told him about how a simple solution like having some paper would make his cockpit more manageable, then nudged him toward the L-chart and we were on our way.
You know when you explain to your student on an approach or something why they just simulated killing themselves? Well, this gentleman must have been part feline because if he was on his own he would have killed himself about nine times in under an hour.
OK, so I give him a little instruction and we're back at it. Just putting in correct radial numbers, let alone actually tracking them, was of utmost difficulty. So he's starting to realize that maybe he's not ready for instrument flying. I'm getting my point across, I think. He's making so many errors that it is starting to become apparent to him.
I suggest we head home and I decide to give him some instruction. I tell him to go direct to a VOR. As he's fiddling with the CDI and before he ID's it I turn the NAV radio off. 'Someone's about to learn a lesson about IDing NAVAIDS' I pleasantly think to myself. We fly for like a minute and he turns to me and says, "Hey, lookie that! Centered needles! Ha! Centered needles!" He was like 90 degrees or more off course.
But I must give him some credit, he landed his brand new $180,000 fully loaded 172 SP on the runway. I wasn't expecting that at all.
