Bring your own seat cushion (very firm!)
 

For all you short people....I have for years now been making seat cushions for the gliding club FROM STACKS OF NEWSPAPER! Wrapped in plastic tape.
And covered in a nice cloth cover. So the cost is ZILCH. (except for your effort).

Your seating must be NON COMPRESSIBLE. Try standing on a newspaper cushion, and it will NOT compress! And you can make it as high or low as suits your preference.

Just try to remember not to leave it out in the rain.....

I am very sorry but I have been guilty of assuming. I assumed you would have been introduced to the aircraft before flight. That would have covered seat adjustment, sun visors, doors, harnesses, escape, fire in flight etc. That would be a one-off for every new type of aircraft you get into. But before all that, a proper lesson plan would have been created and briefed through with you before flight. That is how proper instructors do things. Missing any of these is not really acceptable. Then in flight, I would expect a "pattered" demo so you could see what was expected of you followed by your attempts. Being a normal human being, you won't get it right first time - that is to be expected. Then the instructor really earns their money. Reinforcing what you got right and trying to work out how to fix the things you got wrong - staying calm (and cool) throughout.

Like Piltdownman I too assumed you had been shown seat adjustments etc.
The view above is certainly not what I get at 5' 8" in a PA28 nor a 172.
I had to crank the seat up as far as possible in a 152 to be able to see properly.
If you can't see the cowling out the front you have no reference for anything.
Rather like driving your car while looking out the sunroof.
That instructor is completely at fault and should be replaced.

Really?
 

TTW,

I think I flew with that instructor once; only once. No demo, shouts lots, doesn't change their delivery if you don't get it. It won't help you, and it doesn't give the school or other excellent instructors a good name. Lots of good advice already posted by others that I won't repeat.

Food for though - when I started to fly I learnt with an instructor who (without fail) calmly talked through a demonstration in the air to reinforce what he'd said on the ground. He did this with everything before getting me to do it. For a lot of the initial flying skills (turns, climbs, climbing turns, steep turns etc.) I found it infuriating as I already had a good handle on flying, but from there on in (stall recovery, spin recovery, unusual attitude recovery) I'd got so use to his mannerisms I could (nearly) always repeat his clam demonstration and patter without fail. Who you learn from and how you learn WILL set the bar you start flying from. No one enjoys flying with Captain Shouty McNoPatience.

Just wondered if the OP has ever ridden a Bike, it's much the same principle...
