Which mode restriction helps prevent accidental gear retraction during flight?

• A. Flight mode restricts gear movement to avoid retraction during flight
• B. Ground mode locks wheel brakes
• C. Flight mode disables steering
• D. Ground mode vents hydraulic pressure

Answer: (A)

Mode-based safety interlocks control when gear can move. In flight, the system enforces a restriction that blocks gear retraction, so a retract command can’t be executed accidentally while airborne. This keeps the gear from changing position during critical flight conditions and ensures retraction only happens in the safe, proper phase (typically when the aircraft is on the ground and the system permits it). The other options don’t address gear movement during flight: locking wheel brakes is a braking function, disabling steering affects steering, and venting hydraulic pressure in ground mode isn’t about preventing gear retraction in flight.
