Final answer:
In aviation, when a pilot loses communication with air traffic control, they can squawk a specific transponder code called the 'lost communication' code, which is 7600. This code alerts air traffic control of the communication loss and allows them to assist the pilot in ensuring a safe flight.
Step-by-step explanation:
Squawking for Lost Comm in Aviation
In aviation, when a pilot loses communication with air traffic control, they can squawk a specific transponder code called the 'lost communication' code. This code is 7600, which is entered into the aircraft's transponder. By doing so, air traffic control will be aware of the communication loss and can take appropriate actions to ensure the safety of the aircraft.
For example, if a pilot experiences a radio failure and cannot communicate with air traffic control, they should squawk 7600 on their transponder. This will alert air traffic control that there is a loss of communication and they can provide instructions to the pilot via light signals or other means to guide them safely to their destination or an alternate airport.
