Challenging, but doable. Fly thrust and attitude.
But if you leave the autothrottle engaged at T/O thrust , try to re-engage the autopilot AND try to re-engage stab. trim you are screwed.
As a matter of interest , the flight data recordings from the initial Ethiopian report seem to have disappeared from the internet.
Why ?
The question was did Boeing had NNC for MCAS? When MCAS itself was not disclosed how will they have a procedure for its abnormality?
