Which systems are commonly used to activate the landing gear warning system?

• A. Landing gear handle
• B. Throttles and wing flaps
• C. Elevator trim and flaps
• D. Autopilot and altimeter

Answer: (B)

Landing gear warning systems are designed to alert you when you’re configured for landing but the gear isn’t down and locked. The signals that the system watches are tied to how you’ve set up the airplane for approach—specifically the throttle position and the wing flaps. When you reduce power toward idle or set the flaps for landing, the aircraft expects the gear to be down. If the gear isn’t down and locked, the warning horn or light activates to prevent a gear-up landing. The mechanism relies on these configuration signals, not the landing gear handle alone, and it doesn’t involve the elevator trim, autopilot, or altimeter in triggering the warning.
