Which option best describes the appropriate use of SECURITE in radiocommunications?

• A. Use SECURITE to declare an emergency.
• B. Use SECURITE to request priority handling for a non-safety flight.
• C. Use SECURITE to announce safety-related information when it could affect navigation or safe operation (non-urgent safety messages).
• D. Use SECURITE only when receiving a distress call.

Answer: (C)

SECURITE is the radiotelephony call used to broadcast safety information that does not require immediate action but could affect navigation or safe operation. It’s meant for non-urgent safety notices—things like potential hazards, weather or airspace changes, or other information that pilots should know to maintain safety. It’s not an emergency signal (that’s MAYDAY), not used to request priority handling for a non-safety flight, and it isn’t limited to situations where you’re already receiving a distress call. So describing a safety message that could influence navigation or safe operation, without urgency, matches how SECURITE is intended to be used.
