What does a yellow X indicate in the gear position window?

• A. The gear position cannot be determined
• B. The gear is up
• C. The gear is down and locked
• D. The gear is in transit

Answer: (A)

The main concept here is how to read a gear status indicator when it shows an abnormal symbol. A yellow X on the gear position window means the position cannot be determined from the display. This signals a fault or loss of reliable data from the gear position sensing circuit, so you can’t trust that readout to tell you whether the gear is up, down and locked, or in transit. In this situation, use independent checks—visually verify the gear, listen for gear warning cues, and follow the abnormal gear extension/retraction procedure in the flight manual. The other states (gear up, down and locked, or in transit) would be shown by normal indicators rather than a yellow X.
