The only limitations are likely those built into your flight control system.
Questions:
1) Using this "approach" AF447 could be saved? If so, the maneuver could still be decided (and initiated) at what minimum FL?
2) This stall recovery technique should be incorporated in (SIM) pilots training?
RR_NDB, unloading the wing is used to
prevent entering a stall, even when the aircraft is well below its normal level flight stall speed.
You cannot effectively teach unloading the wing in a simulator. A key element of the training is the feel of near zero g. This type training goes hand in hand with use of AOA indicators. Once a pilot understands the idea, and if the aircraft is equipped with an AOA indicator, then some Sim reinforcement of the training can be performed by pushing to lower AOA indications to near zero actual AOA, (not necessarily indicator zero.)
Once you are actually in a stall, unloading the wing should break the stall and allow acceleration provided you do not progress into a spin. The sooner AOA is reduced to un-stalled ranges, the lower the likelihood of entering a spin.
Once a pilot understands unloading, the concept of pushing the nose down to get flying again seems natural. Then it is just a matter of do you have sufficient altitude to recover?
Sometimes it is a delicate balance between getting the wing flying and not generating too much sink rate. In those cases, an AOA system or a system such as the Airbus Normal law protections is what makes the difference. If your 'Bus is not in normal law though, you are back to basic Stone age flying technique.
