My thoughts are to take care of flying in the following order:
1. airspeed - increasing... pull back on the throttle; decreasing...
push in on the throttle
2. pitch attitude - nose down... pull back on the yoke/stick; nose up...
push forward on the yoke/stick
3. roll attitude - roll left/right to wings level | |

Doesn't #3 usually come before #2? Otherwise, a tightening spiral
might result.

There are a few different ways that advice could kill you.
What you do about pitching should depend more on airspeed than on
attitude. A stall can occur even if you're pitching down, so your
advice to pull the nose up if it's down can be just the opposite of
what you need to do. Instead, you should pitch down (and advance the
throttle) if your airspeed is too low (but first, check your rate-of-
turn or heading indicator to see if you're in a spin; if so, recover
according to the procedure in your plane's POH).
If your airspeed is too high, DON'T pitch up before checking your bank
angle. If you're in a high-speed spiral dive and you apply back
elevator, you could worsen the spiral and overstress the airplane.
Instead, roll level first (and put the throttle to idle), and see what
happens. If the plane pitches up sharply--which can happen because
you're now at high speed with abruptly less load factor--then you may
not need to apply back elevator at all, and indeed may even need some
forward pressure to prevent too steep an upward pitch. | |

If your experience is anything like mine was, you'll have absolutely no problem. The DE I had was a
master of deception on this. He was able to put the airplane in the most awful situation, with hardly any
unusual g's. He was very smooth (and clever) in making the airplane's attitude NOT agree with the
sensory inputs. I don't know how he did it, but it was very effective. Trying to figure out where we were
going based on the seat of the pants just didn't work. So, I'd say focus on your recovery technique (as
other replies have described) and don't worry about the g's.

Your are correct.
Always roll wings level before pushing or pulling the nose. | |

This is NOT the generally taught method.
You must roll the wings level before pulling back to break a dive
or you risk just pulling yourself into a graveyard spiral. | |

| | Guest | Unusual attitude recovery advice sought In addition to all the other good advice you got here, i'll add this.
Recovery should be smooth and deliberate. Not to quick and not too slow,
but above all, smooth. Not so much for the examiner, but for any real life
situation which neccesitates a recovery from an unusual attitude be it imc
or vmc
