Hi Dave,
Inibuilds have updated there London Heathrow scenery,i have a feeling they have included 2 more ATIS Frequencies being 113 and 117 and as i have updated PF3 database it has included them in PF3 FS20 ATIS file.
I tried to do a flight but had to abort it as it was telling me to tune to 113.xxx freq and as my Fenix A320 comms radio wasn't allowing me to do this...so i deleted the 2 abnormal frequencies and PF3 works fine, Flight and ATIS file included with log.
These frequencies are ok in the real world as i have an airband radio so i know i could tune into these if i so wish,
