Definition
An FAA directive titled 'Location Identifiers' that establishes and lists the official letter and number identifiers assigned to airports, navigation aids, air traffic control facilities, and other aeronautical locations in the United States and certain other regions.
Plain English
It is the FAA's official rulebook that decides and publishes the short codes used to name airports and aviation facilities, like 'LAX' for Los Angeles International or 'ORD' for Chicago O'Hare.
Context Anchor
You may see FAA Order JO 7350.9 cited in the Aeronautical Information Manual, airport identifier discussions, charting references, flight planning, and official aviation notices.
Why Pilots Care
Correct identifiers from this order are required for flight plans, ATC communications, and navigation databases; using an outdated or incorrect code can cause routing errors or delays.
Intuition Check
“Order” here does not mean an air traffic control instruction to a pilot. In this context, an FAA Order is an official FAA publication that tells FAA personnel and aviation users how a specific subject is handled.
Example Sentence 1

Example Sentence 2
