It is simple in the SIM to just bring THR LVRs to idle and stall, push the stick forward and recover. For all you know the aircraft hadn't stalled because present simulators are not representative of deep stall and you are not allowed to practice deep stall. So if you did nothing else it wouldn't matter. In Perpignan and AF 447(although self created) the stab had auto trimmed way up and to unstall it required to manually trim forward otherwise recovery was not possible. In another you may require to retract speed brakes or make wings level. These are all critical actions and they need to be done by memory instantly and the PM has to ensure you do or he has to remind you or do them himself. If you forget to switch off FDs it is not disastrous like forgetting the other things. In a hurry in TCAS I have seen people switching on the LS button instead off switching off FDs. FD on or off shouldn't paralyze anyone. Golden rule 1 fly the aircraft. You can't fly a stalled aircraft unless you unstall it. So first unstall it. Then fly it back to the flight path. It seems that all memory items have been removed from the QRH. But stall recovery is discussed in the FCTM and it doesn't say anything about FDs.
