I flight plan corporate aircraft around the world. We always use the ICAO format for filing with ATC, except for domestic U.S. internal flights. We rarely have any problems anywhere in the world , but U.S. domestic flight plans ,especially out of small U.S. airports often give us grief . The reason often given is "the airport isn't in the ATC system" or "the system can't find a waypoint".This also happens a lot when filing a flight from the U.S. to Canada from a small U.S. airport using the ICAO format.
Do you think the U.S. will ever go to the ICAO format for all IFR flights ??
The ICAO format is standard around the world. An added benefit to ATC is all the additional information contained in the format.
Why does the U.S. still use the domestic format that contains very little info ?? In light of recent events would ATC want the most information possible ??
