Ils frequencies - how to?
-
Eg, setting up new airport and would like to add ils and tacan.
Tacan is not a problem,Is there some frequency range for ils that should be respected?
How to come up with the number, I guess it is not “out of blue”?
Is ils somehow bound to tacan channel?Thanks in advance

108.1-111.95 MHz, they are not tied to a TACAN, I would make sure that no other airport is using the same ILS freq nearby though.

Thanks… I’ve (accidentally, trying to use search in forum, for once :D) found some older RedDog post about DME, essentially: DME=TACAN+1063 <59Mhz and DME=TACAN+1053 > 70Mhz
It isn’t quite the purpose, but it gives nice “random” numbers , since if tacan is different then is the result … also and now I know for 108.1-111.95 limit.
-only “problem” are tacan=001X with range 0 … they are require to bit of imagination
-In “Allied Force” ILS was really linked to Tacan , so it was kind of automatic… OpenFalcon changed that and BMS took over … but limits/ranges/rules were unknown to me till today.
Thank you.
Cheers
