Makes me wonder if either or both crews were thinking of this QRH stall recovery information in their attempts to find a stable attitude+power combination:
Initiate the recovery:
• Hold the control column firmly.
• Disengage autopilot and disconnect autothrottle.
• Smoothly apply nose down elevator to reduce the angle of attack until buffet or stick
shaker stops. Nose down stabilizer trim may be required
(My bold)
Then there is this warning which follows:
WARNING: *If the control column does not provide the needed
response, stabilizer trim may be necessary. Excessive
use of pitch trim may aggravate the condition, or may result in loss
of control or in high structural loads.
RegardingMr Elwell: In his testimony he refered to the aisle stand switches as trim actuation switches, which they are not, and additionally described the 737 incorrectly as FBW. He's a Trump appointee trotted out to mouth platitudes in order to keep actual experts as far from the committee as possible.
