Look in your aircraft folder...there should be a file called "airlines.cfg". At "Thomson" to the list, save it, and see if it works.
Perhaps he should update his FS
voicepack, so it includes the Thomson callsign. Just search for the callsign, make sure the checkbox next to it is checked and the checkbox not dark, update the airlines.cfg and then update the voicepack. After that, check in the respective aircraft.cfg that the ATC airline line has the callsign enabled, the start FS
and go fly.
