In the event of a communication failure during an approach, what is the priority action for the pilot?

In the event of a communication failure during an approach, the priority action for the pilot is to establish a hold over a fix. This action helps maintain aircraft safety and situational awareness, allowing the pilot time to assess the situation and prepare for either continuing the approach or making alternative plans. Holding over a fix helps ensure that the aircraft remains within controlled airspace and avoids any potential conflicts with other air traffic.

By establishing a hold, the pilot can gauge whether communication can be reestablished, evaluate the environment for any potential safety issues, and decide on the next steps, such as whether to continue the approach or divert to an alternative airport. It is a crucial part of maintaining safety and control in the event that standard communication procedures cannot be followed.
