> The tendencies without MCAS are fine

FAA seems to disagree..

> ([0], scroll to bottom) Following publication, an FAA spokesman on January 11 provided the additional statement regarding Administrator Dickson’s comments around Boeing’s selected path for meeting Federal Aviation Regulations for the original implementation of MCAS on the 737 Max. The Air Current sought and received comment from the FAA in advance of publication and that is reflected in the story above. We provide the latest response in full:

> The fact of the matter is that the FAA — and the other authorities — determined during a 20-month review that MCAS was a necessary part of the flight control system. We all reviewed and approved the changes to the system as part of the recent certification.

> This is directly addressed in the 100-plus page report [1] that was filed with the Airworthiness Directive. We made it clear that the aircraft would not have been compliant with the stick force and G requirements and higher angle-of-attack without MCAS or some other type of mechanism. The FAA does not tell applicants how to design planes, so the choice to develop MCAS was an engineering decision on the part of Boeing. The FAA’s role is to evaluate and approve proposed designs against the regulatory requirements.
