The definitive “pilot guide” will come out soon enough and airlines will need to rewrite the SOP.
Sadly pilots were not told that the MAX was a dynamically unstable aircraft with a hidden Easter Egg - they had to find out the hard way - by dying.
But essentially:
1) recognise early and turn off Stab cut off switch and manually trim at the trim wheel until aircraft lands - and don’t turn on the cutoff switch
2)recognise early, correct the trim electrically at yoke every time electric trim activates to push nose down. When too many corrections do 1)
3) recognise early and do 2). As soon as trim corrected, turn off Stab cut off switch
4) recognise late - “grasp and hold” and crash so other pilots can learn from the FDR/CVR
