Phrase 1 of 5Airport codes
How an Indian airport code is built
Exam papers and flight plans name aerodromes by four-letter ICAO codes, such as VIDP or VABB. Read the code, then say the place on the radio.
The pattern
You say
departure place tower, callsign, request ATC clearance
ATC says
callsign, departure place tower, cleared to destination place, route, level, squawk code
Example
- You
Delhi Tower, Air India 447, request ATC clearance
- ATC
Air India 447, Delhi Tower, cleared to Mumbai, flight planned route, flight level three hundred, squawk five two one four
- You
Cleared to Mumbai, flight planned route, flight level three hundred, squawk five two one four, Air India 447
The list
| Second letter | FIR | Example |
|---|---|---|
| A | Mumbai | VABB, Mumbai |
| E | Kolkata | VECC, Kolkata |
| I | Delhi | VIDP, Delhi |
| O | Chennai | VOMM, Chennai |
Remember
- ✓A location indicator is a four-letter code group, made by ICAO rules, assigned to the location of an aeronautical fixed station (MATS definitions). ICAO lists them in Doc 7910.
- ✓Every Indian code starts with V. The second letter is the FIR region: A Mumbai, E Kolkata, I Delhi, O Chennai. The last two letters name the aerodrome: VIDP is Delhi, VABB is Mumbai.
- ✓Codes are written, places are spoken. A flight plan's departure and destination boxes take the four-letter code (ICAO Doc 4444, Appendix 2, Items 13 and 16). On the radio a station is its place name and its unit, such as Delhi Tower or Mumbai Control (MATS 12.7.1.1), and a clearance names the destination by place: CLEARED TO Mumbai (MATS 12.16.2.2). REQUEST ATC CLEARANCE is the usual plain request; MATS prints no wording for it.
- ✓Guwahati has its own flight information centre and sub-FIR, and its code starts VE: VEGT (MATS 3.6.4, Table 16-1).
- ✓A few airports near a boundary sit in the neighbouring FIR: MATS Table 16-1 lists Gwalior (VIGR) under Mumbai FIR, and Latur (VALT) and Nanded (VAND) under Chennai FIR. The same table still prints some older codes, such as VIBN for Varanasi and VARP for Raipur; these cards use today's codes.
Now say it out loud, with the examiner playing ATC.
