What is the best practice for coordinating with a helicopter crew during LZ operations?

• A. Avoid radio communications to minimize interference.
• B. Land without prior coordination to save time.
• C. Use only visual hand signals.
• D. Establish a clear communication plan, assign roles, and maintain radio discipline to avoid miscommunications.

Answer: (B)

Coordinating with a helicopter crew during LZ operations relies on a clear, deliberate communication process. The best practice is to establish a formal plan for how the team will communicate with the helicopter crew, assign specific roles to ground personnel, and maintain strict radio discipline to prevent miscommunications. This means designating a primary air-to-ground communicator and a ground safety officer, agreeing on call signs and frequencies, using standardized radio brevity and readbacks, and confirming key actions before they occur. It also includes pre-briefing the approach and departure plan, identifying the touch-down and pick-up zones, and continuously updating the crew about wind, obstacles, and personnel movements. Keeping lines of communication open, with a single point of contact for the helicopter, and ensuring everyone knows their job reduces ambiguity and helps coordinate safe landings, on-loads, and departures. Visual signals can complement but do not replace radio communication in the dynamic environment of an LZ.
