When inbound for recovery, if no radio contact is established, what should the COD aircraft do?

When inbound for recovery and there is no radio contact established, the best course of action for the COD (Carrier Onboard Delivery) aircraft is to return to the base. This decision is based on the principles of aviation safety and standard operating procedures.

Without radio contact, it is impossible to establish the status of the landing environment, including the condition of the flight deck, any potential hazards, or updates on flight operations. Returning to base ensures that the aircraft can land at a facility where communication is possible, and where proper landing protocols can be followed safely. This approach minimizes the risks associated with attempting to recover on a vessel without communication and ensures the safety of both the aircraft and its occupants.

The other options, such as proceeding with recovery or continuing to the ship, could potentially lead to dangerous situations, including landing on an unprepared or unsafe deck. Diverting to an alternate airport, while safer than attempting to land without communication, is less optimal than returning directly to a known base where resources and support are available. Therefore, the choice to return to base in the absence of radio contact is the most prudent and aligns with safety protocols in aviation operations.
