If a pilot has agree to fly with a check pilot, that pilot has the expectation of either having their skills validated for a purpose (rental/job), or skill building. If it is a skills validation checkout, the only expectation will be the the candidate pilot demonstrate that they meet the minimum level of skill for an existing standard - NOT additional training - that's training! If it is to be training, it should be to a standard, and procedure which is industry accepted, and probably exceeds the scope of a checkout.I include within the check-out, a scenario......
If you're using the occasion of a check out to train a pilot (other than a little skill building to meet the expected standard), it is possible that you are doing something which that pilot is not expecting, and you are not formally entitled to do - in some cases, this task is an instructor task, specifically so that there is some assurance that the training is being done to an accepted standard!
If you tried to train me to fly a 70 degree banked turn as an element of a forced approach, I would land you back wherever we came from, and walk away. If you expected me to do one on my own initiative when you pulled the power, we would disagree about the outcome of the checkout, when I refused to do it. I would require you to show me anywhere authoritative, where that was described in a procedure. You couldn't. Then if I continued to be dissatisfied, I would ask the operator or authority how this training would meet the standards. I wonder what they would say - admit to an association with a rogue check pilot?
