What color is the Gear position and lever disagreement indication on the EICAS?

• A. Red (20 second grace period)
• B. Red
• C. Amber
• D. White

Answer: (A)

When the gear position shown by the system and the gear lever position disagree, the indication is shown in red. That red warning is used because it signals a high-priority condition that needs immediate crew attention. There’s a 20-second grace period built into this indication to account for transient or settling conditions during gear extension or retraction, sensor delays, or hydraulic actions. In that short window, the crew has a moment to verify and, if possible, correct the mismatch without the alert becoming more persistent. If the disagreement persists after the grace period, the red indication remains to alert you to resolve the fault. Other colors wouldn’t convey the same urgency or the temporary allowance provided by the grace period.
