Definition
The section of the Federal Aviation Regulations that establishes the requirements for emergency locator transmitters (ELTs) in U.S. civil aircraft. It specifies which aircraft must carry an ELT, the type of ELT required, battery replacement and inspection intervals, and the limited circumstances under which an aircraft may be operated without one.
Plain English
It is the rule that tells you when your aircraft must have an emergency locator transmitter installed and working, when the battery has to be replaced, and how often the unit must be inspected.
Context Anchor
Seen in aircraft inspection records, preflight airworthiness checks, and handbook discussions about emergency locator transmitter requirements.
Derivation
14 CFR means Title 14 of the Code of Federal Regulations, which is the part of U.S. federal law covering aeronautics and space. Part 91 covers general operating and flight rules. Section 91.207 is the specific paragraph within Part 91 that addresses ELTs. The numbering system is just a filing address inside the regulations.
Why Pilots Care
Ensures the aircraft meets legal requirements and improves the chance of rescue after an off-airport landing.
Intuition Check
Do not read this as a piece of equipment. It is a rule citation: the address of a specific FAA regulation about emergency locator transmitters.
