I would've thought so myself, but apparently not for P3D...
As for the frequencies, I have no idea, it's just the GND frequency I have to use on my software so idk. Im not sure how accurate the website I linked in my first post is, but that's the frequency it installed for EHAM. I've just rolled back to the old one, now it's just 121.55
Are frequencies usually accurate on P3D ? Cause for big airports they gotta chose one anway despite the numerous ones available at EHAM for example.
