Still doesn't answer the question of, why if MCAS is required during critical portions of the flight to prevent stalling is disabling of MCAS an acceptable solution for this aircraft?
Introducing a new condition of "We think MCAS is on, but we're not quite sure / it's cutting in and out due to censor disagreements" is preposterous.
- ams6110 8y agoThis might be splitting hairs, but MCAS is not there to prevent stalling. It's there to meet a specific certification requirement on control stick forces at high angles of attack. Yes the intent of the requirement is to reduce the tendency of the pilot to pitch up too much near the stall. But MCAS doesn't prevent stalling. Modern aircraft have many automatic systems that are there to make the pilot's job easier. That doesn't mean they are unsafe to fly if those systems malfunction and have to be disabled.
- linuxftw 8y agoEvery source I've found refers to it as an anti stall system, and the system is designed to limit angle of attack (eg, prevent the system from stalling). It's definitely a safety feature that's required and not an assistive device. It was required for certification, and in fact as originally specified was unsuitable to prevent stalls, so Boeing had to increase the authority of the system to make it functional.
