When is the T-6 landing gear status light green?

The landing gear status light in the T-6 is green when the landing gear is fully extended and locked. This indicates that the gear is in the correct position for landing and is secure, providing assurance to the pilot that the landing gear will support the aircraft during touchdown. Proper verification of the gear status is crucial for safety, and the green light serves as a clear and unambiguous confirmation of the successful deployment of the landing gear.

In contrast to this, the other scenarios represented in the other options do not provide a safe or correct indication. For example, if the gear were retracted, a different signal would be present, confirming that the gear is not ready for landing. Similarly, a malfunctioning gear or one that is only partially extended would generate warning lights or indications, alerting the pilot to an issue that needs addressing before proceeding with landing.
