ICAO Approved Callsigns


Question: Anyone have any experience in getting callsigns approved by ICAO/FAA? What’s the process?

Reason: From small flying clubs to multi ship charter ops, having an operational callsign often boosts the esprit of the outfit and provides a quick UID for others on the frequency…It’d be cool to have a callsign approved for a non-135, organized flying activity whose members are serious about their flying and want to establish a heritage.
