If you observe an unusual forward stick force, which fault is this most closely associated with?

• A. Flap Slab interconnect fault on takeoff indications
• B. Nose gear steering fault
• C. Rudder bias fault
• D. Elevator gust lock fault

Answer: (A)

Forward stick is felt when the airplane develops a nose‑down pitching moment that the pilot must oppose. A flap slab interconnect fault can cause the flap/slab linkage to move out of proper sync with the takeoff configuration, producing an unexpected pitching moment as flaps are commanded for takeoff. During takeoff, with flaps being deployed and lift rapidly changing, this mismatch can create a nose-down tendency, so the pilot experiences an unusual forward push on the stick in order to maintain the desired attitude. Other faults tend to produce steering, yaw, or elevator-specific symptoms rather than this nose-down feel during takeoff.
