Question for the Falcon 7x pilots
What happens if during a trim runaway,or any trim automatic movements, you move the manual trim switches the opposite way?
Would that stop the trim?
No , The manual trim switches can only be used when the HSTA (Horizontal Stabilizer Trim Actuator) is controlled in back-up mode.
the back-up mode is engaged when both channel 3 or the HSTC 3 module (horizontal stabilizer control) and channel 4 or the HSTC 4 module have failed.
Once this channel is activated it will maintain direct and dedicated control of the HSTA.
