In response to being NORDO, what is the appropriate sequence of actions upon finding the duty runway?

The appropriate response for a pilot who is NORDO (No Radio) and has identified the duty runway is to enter downwind with interval. This action allows the pilot to maintain safe separation from other aircraft that may be using the same runway. Entering downwind ensures that the pilot is positioned properly for landing, following standard traffic patterns, and helps to avoid conflicts with other aircraft.

This procedural approach is critical for enhancing situational awareness in a potentially busy airspace, particularly since the pilot lacks the ability to communicate with air traffic control or other pilots due to the radio failure. By entering downwind with awareness of interval, the pilot can visually monitor the positions of other aircraft and manage spacing effectively to promote safe operations in the airspace.

In contrast, options like requesting an immediate landing would not be feasible without radio communication, while initiating a climb to cruising altitude or flying at a higher altitude until contact is made would not address the immediate need to land safely when the duty runway is identified. Engaging in the correct entry into the traffic pattern is the most effective and safe course of action.
