He moved the throttle while you were landing? Where was your hand?? Was it on the throttle and he grabbed your hand?

I took my first lesson with this guy (Not mentioning his name) and even then I was able to manage the pattern, then on the final approach he didn't request control...He slapped my hand!
I lost my second instructor to the airlines and my third instructor got into the flow with me and it went fast, fun and easy.
As an aside I didn't go to ground school for PPL and CPL because I was signed off to take both of exams by instructor number 2.
Anyway back instructor 1,on his landing he kept shifting between full power and Idle and he bounced down the runway...so this guy seemed to be not only a bad instructor but a bad pilot. Or maybe he was just trying to scare me, it obviously didn't work.

My hand was on the throttle and he grabbed my hand.

I once flew with the CFI of a local club on a check ride in the clubs C172. I am an experienced pilot and have worked professionally within the aviation industry however this "check ride" was no more than the CFI showing off at my expense!

Needless to say, I refused to fly with him again.

Control grabbers are an even worse menace in a tandem. Many years ago I had a bad experience with an instructor in a PA18 on floats. He had a habit of grabbing the controls, starting a turn, then releasing them without any kind of handover of control. The first time it led to real confusion about who was in control. Between flights, I told him in no uncertain terms if he did that again, I would walk away, course unfinished. It did not result in a personality change, and he continued to think he was God's gift to aviation, but at least the control grabbing stopped.

During my IR phase I flew with a guy who would tell you to pitch down (I was a bit high during a practice ILS), and seconds later he would shove his yoke forward when he felt that my response didtn't come quickly enough. It always managed to destabilise my approach, and I felt I never got the opportunity to learn. If my responses were too slow (they may well have been), it would have been better to let me figure that out for myself. I later managed to ditch this instructor, but not before he put a real dent in my self confidence. After the switch to a different instructor, I was back on track after two flights fortunately.

There is a big difference between assisting a student, for example by adjusting the pitch attitude gently while clearly taking over control and explaining what you're doing and why, and bashing your hand against the center of the yoke while yelling in the student's ear.

The instructor should have said what they were doing and why, otherwise there is no actual instruction...

If they were signing off on a check ride and had any doubts, they should have stated them clearly.

Otherwise, they aren't doing anyone any favors, not their employer, not the potential customer.

Instructor or no instructor, don’t touch anything without telling me.

If you put your hand on mine, whilst it’s on the throttle, I may remove it aggressively .

Having said that some people just stay nervous - I know a captain of a large aircraft that makes his own “ idle “ by covering the lowest 2” of the quadrant to stop his colleague going to idle before he’s ready .

That was my very strong instinct. But I decided it may not be wise to be fighting over the throttle 15 seconds from touch down, so I just dealt with the consequences of his throttle changes.

Anyway, I am now flying a C172 in a stunningly beautiful area, with virtually no other traffic and fantastic weather. So worth the pain.

Any pics DB? Where abouts are you flying?

I had 3 different instructors during my brief gliding career - the guy who flew me on my trial flight who at that time wasn't yet a fully qualified instructor, a senior bank employee and a fast jet/test/airline pilot. Guess which one continually took back control...

I'm flying again tomorrow, I will try to take some pics, then we can play guess where I am!

Anyone putting their hand on mine without prior consent (which may be implicit, in certain situations :) ) take a grave risk of getting slabbed in their face.

I would pay money to watch someone attempt to bully some of my old students , some of them had very particular skills ; skills acquired over very long careers . Skills that would be a nightmare for any bully :)

Imagine your reaction if your car passenger leant over and switched the headlights or wipers on or off. Or adjusted the radio volume without asking.

Indeed, I used to drive with a passenger who quite regularly did that. His favourite trick was to flick the windscreen wipers on - for some strange reason it must have appealed to his warped sense of humour.

Then again, he was my favourite miniature poodle .....

My instructor (13 years and 600 hours ago) acted mostly as a safety pilot while I was experimenting and learning. Very relaxed.
I've also had the experience, as a passenger with a not very current pic, of pushing the stick when we were on the verge of stalling at low altitude.

Yes precisely. Mine once said "I sit by, and act as little as I need. As soon as I don't feel compelled to act at all during 3 consecutive circuits, I'll send you solo." Things worked out a bit differently, but this chap did push me on the way to my never-forgotten first solo.

Takes all sorts ,
The worst were some of the commercial / FIC instructors I had....clearly for reasons of personality they weren’t ever going to become jet pilots of any variety , and were in some cases bitter and nasty. They are lucky they met the 20 something version of me and not the current one.

And what the hell was up with swanning around with four stripes ? I believe if you have never commanded a commercial aircraft it’s not a valid thing to wear .

Thread drift, though yes, I agree. Four stripes, like "Doctor", or "P Eng" should be respected from being earned, and granted by peers.

As to the topic at hand, if the instructor (and I'm guilty of this) has waited too long before counseling, and then requiring, the candidate to correct, that's not the all candidate's fault. The instructor has to own that, probably with an apology after the "taking control" without a briefing.

JT that was a classic! :}

So I‘ve had instructors before who tried to assist me with nudging the stick. Particularly in my early days of gliding, when learning to center a thermal. Whether this is good practice or bad practice ... I‘ve found that to be ineffective with me. The audio channel would be much more effective - at least to me.
So my question the audience is:
Is this a personal thing, that I am sort of insensitive of learning by feeling the control inputs of another person?
Or is it generally useless to do so?
