ICAO codes

I see that nobody has answered GFletcher's question from around the 8th July about IATA codes and ICAO codes.

IATA codes are those used by the Int'L Air Transport association and apply in the main only to civil airports (altho' there are a few exceptions) .

ICAO codes are allocated to all types of airfields, military and civil , those with or without airline services.

When was the list of ICAO codes done? EGQT was Turnhouse.

And if your sad enough to plot them on a map youll see that there is a logic to them.

Someone already did - long ago - I downloaded the .KML file from Google Community and just checked; it does cover UK (and the world!!)

EGQT was Turnhouse.

Can you put a date of any kind to that?- it is EGPH nowadays.

EGQT was RAF Turnhouse which closed in 96.

As for the IATA codes almost all RAF stations also have an IATA code eg Brize is BZZ, Leuchars ADX, Kinloss FSS.

Thanks - I will add it to the list in the Audit section.

The IATA codes are used on the SITA system, in the RAF its called MMARS (military movements and reservations system). This is used by the airlines instead of AFTN.

A lot of the IATA codes for North American airfields are the AFTN with the first letter removed,and heres some examples.

Goose Bay is YYR in Iata and in AFTN its CYYR. RAF ops at Goose was yyrrrro in aita. Infact all the Canadian iata codes start with Y.
Ohare is ORD in IATA and KORD in AFTN. JFK well thats too easy!

I have two codes which were used around the 1959/60 era - taken from the official Cardiff logs were
EGGL - Bristol Lulsgate
EGVL - Little Rissington
hopefully I may be able to add more to the list or at least confirm a few which may have been in use around that time

Re the question about ocean weather ships Ocean station India was EGRI and the Met HQ was EGRR.
I have an idea that UK ICAO codes were allocated by their connection to a teleprinter hub.

Thanks - the main list has been updated.
