ICAOs, where can I find them.

[TOMARSE]

The game asks for the ICAO. Is the info in the game somewhere or do I just go online and find them? Thanks.

ICAO codes can be found online using any search engine. For example, I am most used to the IATA codes for airports so, if I want to find the ICAO code for Chicago and I know that its IATA code is ORD, I type ORD ICAO into Google and get the result of KORD.

Or just search on Wikipedia - it says it in the details on the right.
