How can you recognize an uncommanded gear extension in flight?

• A. Gear warning horn/light activates; gear down indicator shows down; potential conflicting configurations may exist.
• B. Nose gear is more stable at high altitude.
• C. Wing flaps automatically adjust.
• D. Cabin pressurization changes.

Answer: (A)

Recognizing an uncommanded gear extension comes from the cockpit alerts and gear status indicators. If the gear extends when you haven’t commanded it, you’ll typically hear the gear warning horn and see the gear warning light come on, and the gear-down indicator will show the gear is down. That combination signals a fault or conflicting signals in the gear system—there may be a hydraulic or sensor issue or a misrouted signal causing the gear to extend unintentionally. The other options don’t relate to unexpected gear extension: stability of the nose gear at altitude, automatic wing flap adjustments, or cabin pressurization changes are unrelated to the gear being deployed against your command.
