What is the main purpose of the anti-collision light on the MH-60S?

The main purpose of the anti-collision light on the MH-60S is to alert ground personnel and other aircraft of the helicopter's presence. This is crucial for maintaining safety during both ground operations and flight. The bright, flashing nature of the anti-collision light increases visibility, especially in low-light conditions, making it easier for everyone in the vicinity to identify that the helicopter is nearby. This helps prevent accidents and enhances situational awareness for both crew members and people on the ground or in other aircraft, thus ensuring safer operational environments.

While the other options suggest benefits related to visibility and operational readiness, they do not align with the primary function of the anti-collision light, which is specifically designed for alerting others to the helicopter's location.
