What is the purpose of the white position lights on the T-6?

The white position lights on the T-6 serve the specific purpose of being constantly illuminated. These lights enhance visibility of the aircraft, particularly at night or in low visibility conditions, allowing other pilots and ground personnel to see the aircraft's position and orientation. Constant illumination ensures that the aircraft's presence is well-known in its environment, contributing to overall flight safety.

Though other options might seem relevant, they do not accurately describe the function of the white position lights. For instance, while position lights do play a role in signaling flight status, their primary function is not specifically to indicate active flight. Similarly, they do not provide map illumination nor signal aircraft readiness; instead, their consistent presence acts mainly as a means of visibility and identification in various flight conditions.
