If a landing gear warning horn sounds on approach with gear not down, what is the recommended action?

• A. Immediately extend gear if not already down, verify with indicators, and continue approach with a plan for a safe landing
• B. Disconnect warning horn and continue approach
• C. Lower gear only after full instrument checklist
• D. Ignore and land with gear extended only if safe

Answer: (C)

When a landing gear warning horn sounds on approach with the gear not down, the important idea is to follow the aircraft’s published gear extension procedure and verify the gear status through the indicators before lowering the gear. This keeps you from reacting to the horn with a rushed, potentially unsafe extension if there might be a system fault or a misread indication.

Going through the full instrument checklist ensures you confirm hydraulic pressure is available, the gear selector is in the correct position, any alternate or emergency extension procedures are considered, and the gear down/locked indicators are reliable. Only after this verification do you proceed to lower the gear so you can land safely with the assurance that the gear will actually be down and locked.

Rushing to extend gear without this verification risks a gear that doesn’t extend properly or a false warning that isn’t understood, which could lead to an unsafe landing.
