Under what condition does Pusher Safe Mode engage?

• A. When the aircraft computer cannot determine the flap setting after some malfunction
• B. When the flaps are set to 0 degrees
• C. When the cockpit is in icing conditions
• D. When the landing gear is not fully retracted

Answer: (A)

Pusher Safe Mode is a fault-protection state that activates when the flight computer cannot determine the flap setting after a malfunction. When essential flap data is unreliable, automatic flap commands could become dangerous, so the system steps into a safe mode to prevent misoperation and to keep control predictable while the fault is diagnosed. This means the system avoids acting on faulty flap information and may rely on a known safe default or manual input until the fault is resolved. The other scenarios describe normal positions or unrelated conditions (zero degrees is just a requested position, icing is an environmental factor, and gear not fully retracted is a separate mechanical state), none of which trigger this fault-protection mode.
