Could anyone tell me what ‘app ATC’ is please?
It is approach ATC, a radar service. They will vector (give headings + alts) from normally around 60NM out until you are on the ILS.
Thank you @Insertusernamehere
Are you speaking of Infinite Flight? Otherwise most are at 123.8
To 126.999. If Approach is what you want? And if for Infinite Flight look for Green…
