How come American callsigns are always the flight number and they can say eg. “Delta one seventy seven” where as in Europe it would be “Delta One Seven Seven”. Also, why can European callsigns be eg. Ryanair 43 Xray Foxtrot while American callsigns can’t ? Is there a reason for this or is it just EU regulations ?
I’m just wondering that’s all
- Air carrier and other civil aircraft having FAA authorized call signs. State the call sign followed by the flight number in group form.
NOTE- “Group form” is the pronunciation of a series of numbers as the whole number, or pairs of numbers they represent rather than pronouncing each separate digit. The use of group form may, however, be negated by four-digit identifiers or the placement of zeros in the identifier.
EXAMPLE− “American Fifty−Two.” “Delta One Hundred.” “Eastern Metro One Ten.” “General Motors Thirty Fifteen.” “United One Zero One.” “Delta Zero One Zero.” “TWA Ten Zero Four.”
Oh, but why are EU callsigns like Shamrock three four november?
That would be the European regulations. They are different.
In the US and Canada, the ATC are more fast paced and just want to keep Traffic moving. So they will say the callsigns like you suggested. Also for the RyanAir43 Xray foxtrot, thats because when flights come in to an airport at a certain time, other flights May also be arriving or departing at the same time with similar callsigns. So there might be a RyanAir 4921 arriving at Shannon and at the same time, there may also be a Shamrock 4921 arriving. To prevent confusion during radio communication, the RyanAir will get a special callsign like you said. Its also not just the EU. Its all over the world. Although I haven’t seen it being used in the US
