exactly...it's on every website I looked at, but speak to ICAO. They say it no longer exists.
You can buy a list of all the current codes from them, and KISM and a number of others is missing. I called & asked about them & they said the country involved (the US) had deleted them.
I doubted her but she said nope...speak to the US. KISM is not a current ICAO code...
I doubted that was the case but wasn't really in a position to argue....so any pointers of where to go/who to speak to much appreciated.
