I am not disputing that BPF once the student gets the point about AoA you can say what you like. During the first 20 hours you should say what your actually doing then they might have a clue.

That's right, "SHOULD".

Otherwise, he/she might be wasting money accumulating flight time with an instructor, without getting it right.

With a good home work and use of the flight simulator, you could accelerate the flight training and optimize the cost structure.

The original poster is a presolo PPL student. Please describe a situation where during PPl training you would stall the airplane by lowering the nose ?

For that matter describe any plausible scenario where this scenario could occur in a typical club SEP ?

in my opinion if you get into a stall while flying inverted then you don't deserve to have a plane licence in fact you don't even deserve to have basic human rights
Why? I did that, accidentally, with an instructor on aerobatics at Las Vegas.
The Zlin flipped 180 before I caught it, and I was flying normal way up, wondering what had happened.

I can think of no possible scenario where pitching nose down during a stall/spin recovery, aggressive or not will cause the aircraft to stall.

I do not agree. Theory should be taught on the ground, actions should be taught in the air. The concept of AoA and its role in the stall and stall recovery is theory. What you need to do in the airplane is lower the nose in order to unstall the aircraft therefor that is what I believe instructors should be telling presolo students when teaching ex 12.

Why should the stall be any different then all the other practical aspect of presolo ab intitio training. For example when you want the student to increase power do you tell them to "open the carburetor throttle valve" or "push the throttle in" ?

Common terminology is 'advance the throttle'

Well personally i never say lower the nose, be it with low hours or thousands being instructed.

Maybe comes from my driving heavy goods vehicle instructor instructor course for the uk army.

I said straight ahead at the round about and thats what happened 27 tons of off road recovery lorry straight ahead over the top of the round about.

I am pretty sure if the stall warner went off in a steep turn with a RAF QFI instructor flying and you had instructed lower the nose all you would get is a boot full of rudder to pull the nose towards the ground.

And I use advance the ..... power levers/rpms or throttle on sep types

This is what a few people here seem to be missing. Saying "lower the angle of attack" isn't just classroom based theory, it's what you need to do to recover from the stall.

In a busy aircraft working in three dimensions, you need to be clear and concise with your instructions. Saying lower the nose is all well and good, but lower relative to what? Mad jock has given the example of a steep turn, lower relative to the horizon would be achieved by yaw, and would not help lowering the angle of attack to get you out of a stall.

.... and the standard terminology for reducing AoA is "centrally forward".

Anyway, back to pricing. I think many of us will be increasing prices in the coming weeks. Most have been absorbing the pain for the last few years but with growth on the horizon.........

Thank you all once again for the comments, you've certainly given me a lot to think about! I think I'm going to stick to where I am at the minute but maybe visit one or two of the other clubs in the area anyway (can't hurt to just have a nose about). I really don't want to do anything to knock me off course at the minute.

Just FYI, before my first lesson on stalling I was give a full 1 hour brief on the theory of the stall. Learned about (amongst other things) the AOA, lift coefficient, lift formula as well as the signs of approaching and developed stall etc. When out on the lesson the recovery instruction was reduce AOA with control column centrally forward.

To answer an earlier questions my instructor at Tollerton was Ben but unfortunately he moved on just before Xmas. I'm still getting to know the new chap but all seems good so far.

I would avoid Donair they don't seem to know what they are doing with the EASA changes and do not have an examiner on hand to assist.

The CAA issued a safety notice about this, just this month!

I guess I am a bad instructor because all of my students get sent on their first solo with a firm understanding on how to recognize an impending stall and take immediate action by lowering the nose if they get into one.

They will however be blissfully unaware of the effects of compressability, reduced thrust at high altitudes, stalls with the autopilot engaged and the correct response to a stick pusher activation

Very interesting

A lot of interesting stuff above but most of it nothing whatsoever to do with the original subject of the thread.

It seems to reflect the fact that most of the inhabitants of GA would much rather head off in some theoretical direction rather than address the day to day problems such as why a flying club has to hike the price so much.

A bit like re-arranging the deck chairs on the Titanic !
