When you have NORDO, what communication method should be employed?

When operating under NORDO (No Radio), the appropriate communication method to employ is to make calls in the blind. This means that pilots will announce their intentions and position over the radio without being able to hear any responses. It is essential in this situation because it allows other aircraft in the vicinity to be aware of the pilot's actions, helping to maintain safety and situational awareness in the airspace. By making calls in the blind, you contribute to the communication flow, even though you cannot receive any communications back.

Monitoring frequencies can be important in normal operations for situational awareness, but it is futile when NORDO since you cannot receive any transmissions. Using an emergency frequency is typically reserved for distress situations where communication is possible; however, if NORDO is indicated, it means permanent or ongoing loss of communication capability. Contacting ground control would also be ineffective in a NORDO scenario, as ground control relies on two-way communication, which is not possible without a functioning radio. Thus, making calls in the blind is the best choice to ensure safety and communicate intentions in a NORDO situation.
