Could MCAS interfere with the terrain escape maneuver? I think that could be the worst moment for MCAS to activate.
I read that you said you are not a pilot. You need to understand that Airbus, Boeing and Embraer all use FBW technology that would prevent excessive pitch attitudes in an EGPWS recovery. The stick shaker can be expected to activate but there may be no stick pusher fitted as the software will not allow pitch up to an excessive AoA. JUST LIKE MCAS. Non pilots seem to be getting indignant about a piece of software "taking over" control of the elevator. Well we already have that in all the FBW aircraft. The big difference is that the B737 is not FBW and Boeing allowed input from one AoA vane. The concept of software limiting pitch is sound. Just like anti tail strike parts of the software.
