hot off the press (from Flight) ...
one part of the fix concerns/interests me ...
"If those inputs (talking about upgrading the system to compare the two sensors) vary by more than 5.5°, the system will inhibit MCAS and the entire speed trim function for the remainder of the flight," a Boeing official says. "That first level of protection… will keep MCAS from ever firing in the case of a single angle-of-attack" error, he adds
ok, you'll no doubt have some "MCAS INOP" warning. But if you can fly the remainder of the flight without MCAS, why have it in the first place ? How can you be sure not to encounter an MCAS event later in the flight ?? Is "MCAS OP" (as opposed to MCAS INOP) on the MMEL ??
why do we need another stick pusher ? ie we have good systems already protecting the plane before we had MCAS ?
another day in paradise, or is paradise one day closer ?
