How is pitch trim force accomplished?
An electric motor driven actuator moves the horizontal stabilizer angle of incidence.
When does the trim cutout on all axis?
After 3 seconds
Which trim will sound an aural alert after 3 seconds of holding it?
Pitch Trim only
How are pitch trim commands normally issued with the autopilot disengaged?
The spring-loaded control wheel pitch trim switch commands the Flight Control Electronics (FCE) 2, which in turn commands the Pitch Trim Actuator (PTA).
How are pitch trim commands normally issued with the autopilot engaged?
The Automated Flight Control System commands the Flight Control Electronics (FCE)2, which in turn commands the Pitch Trim Actuator.
How are pitch trim commands issued with PITCH BKP MODE switch in the BKP position?
The spring-loaded PITCH BKP DN/UP trim switch commands the Flight Control Electronics (FCE) 1, which in turn commands the Pitch Trim Actuator
Is the autopilot available with the PITCH BKP MODE in the BKP position?
No
How are roll trim commands issued?
The spring-loaded ROLL trim switch commands the Trim Actuator Controller
How are yaw trim commands issued?
The spring-loaded YAW trim switch commands the Trim Actuator Controller
Which axis of trim commands are issued through the Flight Control Electronics? (FCE)
Pitch only- Manual (AP off) and Automatic (AP on) through FCE 2, Backup through FCE 1
IS pitch trim motion rate a function of airspeed in both Normal and Backup modes?
Yes, in both Normal and Backup, the higher the airspeed- the lower the trim rate, and vice versa.
