PERFECT FLIGHT - FSX MISSIONS AIRBUS A321 SWISS AIR
I fail to see what is "Swiss" about it - except the flight plans and the livery. All audio - the briefings, background ATC chatter, cabin announcements, the voices of PF and PNF - all are American English. I think that the product video is very misleading in that regard. Be aware that Garret Smith's FMC is required to be downloaded and installed (by you) if you want to use an "MCDU" in the A321 that is coming with it.
