This seems to tell a different story that what I have heard before. That MCAS was originally designed to 0.6 degrees, and the test flights showed it needed 2.5 degrees. Now, this says the test pilots didnt know about the 2.5 degrees?
Not necessarily. If it was demonstrated during test flights that with the original MCAS longitudinal stability criteria (i.e. required stick force) were not met, that would have been all the pilots knew at that time.
The subsequent authority increase to 2.5 degrees could have been kept from the test pilots. They would just demonstrate that the revised MCAS now meets the FAA requirements.
