Also, where will we see the FAA response to JATR:
Recommendation R3.4: The FAA should review the natural (bare airframe) stalling
characteristics of the B737 MAX to determine if unsafe characteristics exist. If unsafe
characteristics exist, the design of the speed trim system (STS)/MCAS/elevator feel shift
(EFS) should be reviewed for acceptability.
And
Recommendation R3.5: The FAA should review 14 CFR 25.201 (Stall Demonstration)
compliance for the B737 MAX and determine if the flight control augmentation functions
provided by STS/MCAS/EFS constitute a stall identification system.
