Hi TSIO540,
Surely selecting flap 1 after the fact is a bit moot..
Your first actions must be to get out of the stall "(no longer stall indications):" by reducing the AoA.
The other actions are listed to aid recovery to your original flight path and are done sequentially and without any significant delay.
If you received a stall warning at 2,000 ft (say whilst trying to intercept the ILS) then you must recover without contacting the ground. Selecting F1 will aid in minimum height loss whilst avoiding any "stall stall" caused by the +ve delta g you will need to pull (which is not felt in the sim) in order to change the trajectory.
"THRUST
SPEEDBRAKES
FLIGHT PATH RECOVER SMOOTHLY
• If in clean configuration and below 20 000 ft:
FLAP 1 SELECT
Note: If a risk of ground contact exists, once clearly out of stall (no longer stall indications), establish smoothly a positive climb gradient."
