Early coordination with the carrier’s marshal control is essential for safe helicopter arrivals. Marshal control acts as the point of contact that sequences inbound helicopters, communicates directions, and relays important information about the ship’s status, winds, and traffic. Reaching marshal control at a distance of 25 miles out gives enough lead time to receive instructions, obtain wind and deck status, and slot the helicopter into the approach flow without rushing the landing team. It also allows for any necessary holding or routing adjustments so the deck and air space are prepared.

Contacts at 10 or 15 miles would leave too little time to resolve conflicts or brief the approach, while 30 miles is unnecessarily far given typical carrier operating procedures and radar/communication ranges. The 25-mile distance strikes the right balance between readiness and efficiency.
