However,erroneous MCAS activation does not look like a typical stabilizer runaway, which is continuous un-commanded (runaway) movement of the stabilizer. During the accident flight, the stabilizer movement was not continuous; the MCAS commands were bounded by the MCAS authority (up to 2.5°); the pilots were able to counter the nose-down movement using opposing manual electric trim inputs; and after the pilots released the manual electric input and MCAS was reset, there was not another MCAS command for 5 seconds.
To incorporate MCAS, the basic column cutout function had to be inhibited during the MCAS activation. Pulling back on the column normally interrupts any electric stabilizer aircraft nose-down command, but for the MAX with MCAS operating, that control column cutout function is disabled.
e mi sa ‘ che qualcuno qui ha pestato
