Of course an airline that never touches the EUR region does not need 8,33 spacing, however of course it is standard equipment on all airbus types as well.
The next time one of you (Flight Crew) steps into a Level D simulator would you mind checking the channel spacing? I'm currently working on a new A320 communications model for a Level D simulator and the Airbus data package for the aircraft defines 25kHz spacing - this is from Airbus simulator data package identified as GO5 D23400500 ATA100 Chapter 23-10 Issue 2 (Aug 31/1987). Note the date... I assume there is a revised s/w load for the RMP that allows 8.33kHz spacing, but it would be useful to know if the current (in-use) simulators have been updated, or retain the original configuration.
Thanks, GY
