Which computer system caused the accident of the 737 MAX?

Which computer system caused the accident of the 737 MAX?

MCAS
The 737 MAX’s flawed flight control software MCAS was accidentally triggered on both Lion Air flights because a defective angle of attack (AOA) sensor had transmitted incorrect information about the position of the plane’s nose. Although there are two AOA sensors on the 737 MAX, MCAS was only connected to one of them.

Is the 737 MAX dynamically unstable?

So Boeing produced a dynamically unstable airframe, the 737 Max.

What are the issues with Boeing 737 Max?

According to the FAA, this could potentially “affect the operation of certain systems, including engine ice protection, and result in loss of critical functions and/or multiple simultaneous flight deck effects, which may prevent continued safe flight and landing”.

What’s the issue with the Boeing 737 autopilot?

The issue with the B737MAX as detailed in the Emergency Airworthiness Directive from Nov. 7, 2018 is not that the plane is applying a nose-down elevator input through the autopilot servos — this would be trivial for the pilots to overcome, even if the servos failed to declutch when the pilots pulled the yoke.

What to do in case of 737 MAX failure?

In case of failures requiring urgent response, the pilots will perform the most important actions by memory and will then follow the checklist. On the 737 MAX it is a paper checklist and not an electronic checklist that is immediately displayed like on the Boeing 777.

How does the elevator work on a Boeing 737?

Most transport category aircraft, including B737, have the elevator, the main surface controlling pitch, attached to a horizontal stabilizer that is also movable. The elevator is controlled using the control column (yoke), while the stabilizer is moved using the trim wheels on the central console.

Is there a stick pusher on a 737?

The stick pusher servo is similar, but the stick pusher is designed to drive full nose down and release almost immediately.
