Why would it not? You still have to be able to fly the thing in case of a dual engine failure.
MCAS has one function: give the MAX 8 flight characteristics that are similar enough to previous versions to not require significant training.
In fact, it's only when the engines are actually working that you'd need this... they're more powerful and further forward, meaning that at high thrust the aircraft will have more of a tendency to pitch up.
- salawat 8y agoActually, the engines don't need to be on for the problematic behavior to manifest since the extra lift at high AoA is a direct result of the geometry of the wing+nacelle.
- cal5k 8y agoThat's fair, but I can't imagine it would be a problem at the attitude required for optimal glide slope in an engine-out scenario?
- salawat 8y agoYou are correct. The parts of the flight envelope where this is a problem are very high (approaching critical) AoA, or in a very tight, highly banked turn. These would not be maneuvers I'd imagine any pilot engaging in without engine power except maybe in the most dire circumstances.
