But Im not a pilot. (getting tired of having to say that)
5 ways to cutoff MCAS 2.0:
(1)(2)(3) same for v1.0
(4) Duck tape the left AOA to +75 deg before takeoff
(5) Install a modified build into the left FCC that mimics a recurring bitflip on the MCAS Engaged flag. Then takeoff.
(3) or any of the cutout switches (there are connected in serial).
(4) or the right AoA (any too high differences disable MCAS).
(6) Move the yoke in the opposite pitch (MCAS V2 grant elevator authority).
Your (6) will only work on a NG... the column cutout is disengaged on the Max when MCAS Engaged is TRUE. Also the idea is misfunction rather than pilot error. Ie something that happens beyond the pilots control.
Right/leftness is immaterial.
The NG don't have MCAS anyway...
You are right that the column cutout is disengaged for MCAS trim stabilizer activation, but the stabilizer trim column cutout have nothing to do with the elevator. According to the MCAS fix list, the elevator authority is implemented directly into the MCAS V2, so MCAS will stop moving the stabilizer before compromising the elevator authority. It's a bit tricky, but it effectively disable MCAS at some point.
