instructors tend to be reluctant to train us for something that could never happen to us.
"Training" implies the ability to demonstrate a sequence where necessary. After all isn't that what the most junior flying instructor is required to do in a Cessna? It is indeed a rare simulator instructor who has the confidence and technical skill to confidently demonstrate a hand flown IMC sequence. Engine failure at V1 for example. Jet Upset is another. It is easier to gabble from the jump seat.
That is entirely understandable as it would too embarrassing if they stuffed up a demonstration. They might be able to talk the talk but very few can walk the walk in front of the student. . That is precisely the reason why check captains who are simulator instructors avoid demonstrating; even though a pilot under training in the simulator can often benefit from first observing a good demonstration before having a go himself. Just like our junior flying instructor and his student pilot in their Cessna.
It should be relatively easy to make time in a simulator session if you have the mind to. All you need is a modicum of common sense and avoid long drawn out briefings when the time should be spent flying the simulator.
Re the highlighted quote. Instructors are not necessarily reluctant to train us for something that could never happen. That is just an excuse, It is just they know they are not competent to demonstrate; despite their paper qualifications as examiner/check captain or what have you.
