MCAS is a funktion of the FCC.
There is no reset.
If either one of the FCCs get a given AOA value that represent Stall for him and all these things are given
- MCAS is enable for airplane model by program pin selection
- Autopilot is disengaged
- Flaps are up
- Pilots are not commanding stabilizer trim (Manual mode).
he activate the MCAS.
If the left AOA is ****ty, than only FCC#1 do the stuff on the left side like stickshaker and on.
If the right AOA is ****ty, than only FCC#2 do the stuff on the right side.
If the AOA of the aircraft is really that high to activate the MCAS than both FCCs do their stuff on their side (i.e. stickshaker on both sides)
If the value of an AOA improves, the FCCs stop their MCAS signal - yes you can call this a reset...
