When does the red down arrow appear on the landing gear indication panel?

• A. When one or more gear are not locked down after gear extension.
• B. When all gears are locked down and down.
• C. When the airplane is on the ground and weight on wheels is detected.
• D. When the landing gear is fully retracted.

Answer: (A)

The red down arrow on the landing gear indication panel is a warning that one or more gears have extended but failed to lock down. When gear extension completes, each leg must lock in the down position with its cam/lock. If a lock does not engage, the red arrow illuminates to alert the crew that gear is not confirmed as down and locked. In normal, safe gear-down configuration, all gears are shown as locked (typically with green indicators) and the red arrow is not lit. The red arrow isn’t triggered by simply being on the ground or by weight-on-wheels status, and it isn’t related to a fully retracted gear condition.
