Hi Jon,
Any of the following form our website FAQ's help at all? Particularly the last one.
Q: Sometimes PFE ATC spells out the entire airline name rather than use the call sign.... other times it's correct.
A: The problem can occur when using Super Traffic Board and telling the aircraft to 'depart now'. If you leave aircraft to depart at their correct times this problem does not occur.
Q: Why do I hear ATC calling the aircraft make rather than the actual airline call sign?
A: Please check under the Technical Tab in FSUIPC (or look under the GENERAL section the FSUIPC.INI file) and set the TCASid entry to FLIGHT. Programs such as AIBlast and FSHotSeat appear to change these settings which make them incompatible with PFE
Q: I've just installed the new PFE voice set expansion pack but I still hear ATC using the three character airline ICAO instead of the full call sign
A: This can happen for a number of reasons... (1) you are using the original and new voice sets together, so if the current controller's voice set is using one of the original voice sets the number of full call signs is restricted to approximately 150 call signs. When only using the new voice sets the number of call signs available is over 1,000.
