What should a pilot do if they lose communication with ATC?

When a pilot loses communication with Air Traffic Control (ATC), the appropriate action is to follow established lost communication procedures. These procedures are designed to ensure safety and provide a standardized method for pilots to follow when faced with communication failure.

These procedures typically include maintaining altitude, following the last assigned route or heading, and attempting to re-establish communication on the appropriate emergency frequency, such as 121.5 MHz. By following these guidelines, pilots can effectively manage the situation and maintain safety while still being prepared to navigate toward their destination.

The other actions, such as immediately returning to the nearest airport, initiating an emergency landing, or turning off all navigation systems, would not be suitable responses. They could create additional safety hazards or lead to violations of regulations, as they may not consider the overall situation and the need for continued navigation or adherence to airspace rules during a communication failure.
