2
What functions does the FAC perform?
“BeSWiFT RATTY”
Be ta Target
“S peed, speed, speed (Flaps 2 - FULL - 100’)
Wi ndshear (reactive threshold)
F light Envelope Protections (Left side of PFD)
T ail:
- Rudder limiting
- Alternate Law Yaw
- Turn Coordination
- Trim Rudder
- Yaw Damping
Is full rudder deflection available during all flight regimes?
No. Rudder deflection is limited as a function of airspeed
How are the flight control surfaces controlled and actuated?
All surfaces are controlled electrically and actuated hydraulically
When is automatic pitch trim available?
In flight under Normal Law with bank angles less than 33 degrees with or without autopilot engaged
