Definition
A notice issued by the FAA, typically through a NOTAM or other official channel, that alerts pilots to security-related restrictions, requirements, or hazards affecting flight operations in a specified area. Security Notices may address temporary flight restrictions for national security events, special procedures around sensitive airspace, or requirements for identification and contact with authorities.
Plain English
An official warning that tells pilots about security rules or restrictions they must follow when flying in a particular area at a particular time.
Context Anchor
Seen during flight planning, in preflight briefings, airport notices, or official aviation information sources when a security issue could affect a flight.
Derivation
Security comes from a Latin word meaning free from danger or care. Notice comes from a Latin word meaning something made known. Together, the term means security information that has been officially made known to the people who need it.
Why Pilots Care
Failure to follow a Security Notice can result in denied access to the aircraft, flight delays, or regulatory violations.
Intuition Check
Do not read Security Notice as a casual reminder to be careful. In aviation, it means an official security-related notice that may contain instructions or restrictions a pilot is expected to follow.
Example Sentence 1
