8.33KHz COM Radio channel bandwidth

For many years, MSFS has used the 25Khz COM radio band channel spacing.
For a number of years, particularly in Europe, Aircraft Radios have been produced & used that use 8.33KHz spacing, and this require 3 digits after the decimal point to uniquely identify each channel frequency.
These radios are starting to be introduced worldwide.

So, the $64,000 question is, will FS11 support 8.33KHz channel radios, and if so, will existing radios be compatible --

Are there any existing FSX aircraft being produced with working 8.33KHz radios.?

Actually, FS since FS2002 has supported 12.5 KHz channel spacing...

...including of course three decimals, such as 118.875

I rather doubt though that FSvNext will support 8.33 KHz steps.

The International Civil Aviation Organization (ICAO) has mandated the reduction of VHF communication channel spacing in Europe from 25 kHz to 8.33 kHz for all aircraft operating above 20,000 feet.
I was not aware that there was ever, in the real world, a 12.5Khz Airband Channel spacing. ?

There use to be an 50KHz Airband Channel spacing, but those radios were uncertified many years ago.

Some research indicates that the USA is looking at 12.5Khz for "agencies" like police & firefighters, and even the future of 6.25 KHz, but this does not seem to apply to USA Aviation.

But some of the newer Aviation Radios are switchable to tune in 12.5 KhZ steps. Others in Europe in 8.33Khz steps.

CONFUSING !!!

However, if currently FS can support 3 digits after the decimal point, then I suppose it therefore can specify the 8.33 KhZ spacing. (or 12.5 Khz) ( good news )

The potential problem, as in the real world, will be for all those with exsiting aicraft fitted with Radios that only tune to 2 digits ( 25 Khz), be be updated with new Radios with the 8.33Khz spacing. ( and or 12.5 Khz) !!

If this is not done, then reading and using Real World Frequencies from newer approach plates (etc), will have problems.

AS far as FS11 is concerned, it will be interesting to see what DATE, ACES choose to use to reference FS11's Nav Data, airport data, etc.....
