- check that using the trim rocker buttons or the control column cutout switches doesn't stop the STS
- possibly, check that when the conditions that should stop STS motion are reached (course limitation), STS continues because the CPU is not ready to evaluate the closing parameters.
Try explaining that to the worlds tabloid media.
Boeings big problem now is not getting the Max certified.
It is convincing people they should fly on an aircraft that has been bodged up to continue flying half a century after design so the company can make a nice profit.
Why were the pilots expected to upgrade to the Max using just an Ipad?
To save money on conversion and simulators.
As a retired Reuters journalist I can assure you the Max will not be flying before Easter next year.
Selling it will be interesting.
