A 7600 emergency reply signifies an aircraft

• A. Fuel exhaustion
• B. Onboard emergency
• C. Communications failure
• D. Medical issue

Answer: (C)

Understanding how pilots communicate emergencies: transponder codes are quick signals to air traffic control about the aircraft’s situation. The 7600 code specifically indicates a loss of two-way radio communications. When ATC sees that code, they shift to lost-communications procedures and rely on the last assigned or expected route and altitude, while the aircraft remains identified on radar by that code. This code is reserved for communications failure, not for fuel issues or medical problems. Those situations are handled through different procedures, with 7700 used for general emergencies.
