How many nautical miles aft should COD aircraft be established during a straight-in approach from port holding?

During a straight-in approach for Carrier Onboard Delivery (COD) aircraft from port holding, it is essential to maintain a proper visual and operational separation from the carrier and other aircraft. Establishing the COD aircraft 3 nautical miles aft helps ensure that the aircraft is safely positioned during the final approach while allowing sufficient spacing between it and any other operations taking place in the vicinity.

This distance provides an adequate buffer to manage the dynamics of carrier operations, including the wake turbulence that may affect the approach trajectory. Additionally, it allows for any potential adjustments in the flight path that may be necessary due to wind changes or other environmental factors, while still facilitating a timely and safe landing sequence.

Choosing a distance such as 1 nautical mile would be too close and may not allow for adequate separation. A distance of 5 or 7 nautical miles would unnecessarily increase the time and distance involved in the approach, which could lead to increased fuel consumption and other logistical complications without added safety benefits. Thus, 3 nautical miles is the optimal distance for conducting a straight-in approach safely and efficiently.
