Which combination of control positions is commonly used to activate the landing gear warning system?

• A. Throttles and wings and cowl flaps
• B. Flaps and slats
• C. Elevator and rudder
• D. Cabin pressurization

Answer: (A)

Landing gear warning systems are meant to alert you when you’re on a landing approach or in a configuration that looks like one, but the gear isn’t down and locked. To determine that scenario, the system uses signals that indicate both engine power and the wing/landing configuration. When throttles are set toward an approach/landing power and the wings (flaps/slats or other lift devices) and related engine/cowl settings reflect a landing configuration, the warning logic expects the gear to be down. If it isn’t, the warning activates. That combination—throttles and wings and cowl flaps—provides a reliable cue that you’re in a landing setup, so it’s the typical trigger for the warning horn. The other options don’t form that same landing-configuration signal: elevator and rudder are primary flight controls but don’t indicate the landing configuration; cabin pressurization isn’t related to gear status.
