Title: Decoding the Skies: What ICAO Doc 7910 Tells Us About Every Airport on Earth

Subtitle: Why your luggage tag says "JFK" but your pilot files a flight plan for "KJFK".

If you have ever looked at a flight tracking app like FlightRadar24 or listened to Live ATC, you have seen a cryptic 4-letter code flash across the screen: EGLL, KJFK, LFPG, YSSY. Title: Decoding the Skies: What ICAO Doc 7910

To the untrained eye, these look like random serial numbers. To a pilot, they are as essential as a street address is to a mail carrier. These are ICAO location indicators, and the master key to understanding them is a dense, 200+ page PDF officially known as ICAO Doc 7910.

Let’s open the hood on this crucial (and surprisingly fascinating) aviation document.

The Pilot's & Dispatcher's Guide to ICAO Doc 7910

Document Title: Location Indicators Publisher: International Civil Aviation Organization (ICAO) Purpose: To provide a standard coding system for every geographic location relevant to international aviation.

Scenario A: Filing a Flight Plan

When filling out the ICAO Flight Plan form (FAA Form 7233-4), you must use ICAO identifiers, not IATA codes.

• Incorrect: Origin LHR, Destination CDG.
• Correct: Origin EGLL, Destination LFPG.
• Doc 7910 is the verification source.

How to Search Within a DOC 7910 PDF

Once you obtain the official file, efficient searching is key. Here are tips for users: If you have ever looked at a flight

• Use the Bookmarks Panel: The PDF is formatted with nested bookmarks. Open the navigation pane and expand "Part I" to jump directly to the "K" section for the USA.
• Search by Code: Press Ctrl+F (Cmd+F on Mac) and type the four-letter code (e.g., KLAX). Make sure you type it in uppercase.
• Search by City/Airport Name: Some versions of the PDF have an index at the back. Search for "London" to find EGLL, EGLC, etc.
• Check the Amendment Record: Before trusting the PDF, go to the front matter. Look for the "List of Amendments" to see the last date the data was updated.

2. Safety and Collision Avoidance

If two airports in different countries shared the same code, the consequences would be catastrophic. DOC 7910 prevents duplication. The system ensures that LFPG always means Paris, France, and never another airport.

Common Mistakes When Using Location Indicators

Even with the PDF in hand, professionals make errors. Avoid these:

• Confusing IATA and ICAO: A pilot might type "JFK" into an ICAO flight plan box.
  • Correct: KJFK.
• Using a code without checking "Active Status": The PDF marks inactive fields with parentheses or notes. Always verify the "Status" column.
• Assuming the code is the Airport: Doc 7910 includes codes for non-airport facilities (e.g., VOR stations, RRCs). Ensure you are selecting an AD (Aerodrome) or APT (Airport).

The Breakdown:

[First Letter] – World Region The first letter identifies the continent or major geographical region.

• K - Contiguous United States
• C - Canada
• E - Northern Europe (UK, Scandinavia, etc.)
• L - Southern Europe (Spain, Italy, France, etc.)
• B - Caribbean & Greenland
• M - Central America
• S - South America
• Z - China & Korea
• R - Japan
• V - India
• Y - Australia
• A - South West Pacific
• O - Middle East
• H - Africa (North/Northeast)

[Second Letter] – Country/Sub-region The second letter typically identifies the specific country within that region.

• Example: In the code EGLL:
  • E = Northern Europe
  • G = United Kingdom (Great Britain)
• Example: In the code KJFK:
  • K = Contiguous US
  • J = (In the US system, the second letter is often part of the local area identifier).

[Third & Fourth Letters] – Specific Location The final two letters identify the specific airport or facility.

• LL in EGLL refers to London Heathrow.
• JFK in KJFK refers to John F. Kennedy International.

Section 1: Alphabetical List of Locations

This is the most used section. You know the name of the city, but you need the code.

• Search: Look up "Paris."
• Result: You will find LFPG (Charles de Gaulle) and LFPB (Le Bourget).

📄 Core Purpose

The official global registry of location indicators assigned to aerodromes, flight information regions (FIRs), and air traffic services (ATS) units. Used for ATS messaging, flight planning, and ATC automation.
