I've started flying helicopters in X-plane around Lincolnshire, UK and am trying to use RAF Cranwell, Waddington and Coningsby tacan's to navigate my way around. Whenever I enter a frequency into nav 1, and make it an active frequency I pick it up as DME, just not VOR.


I personally thought tacan is basically a military version of a VOR, but it seems to me it's more like a DME.


My question is am I write or wrong in my theory? Or is X-plane 10 portraying tacans in the wrong way (which I doubt) :P And also how do the military use tacan to navigate, and how can I start doing this? 


Thank you very much :)

TACAN has VOR/DME but for military aircraft only - you need a military radio that operates in the 960-1215 Mhz range. It might be colocated with a VORTAC  that they let civillians use for navigation, you'll have to check your charts. I'm not so sure that they even have the TACAN modeled in XPX but I could be wrong as I don't own any military jets.


Most US planes use channels  too so you don't actually see  the frequencies.

Thank you Donor for your reply.


That makes sense, I am using the sikorsky SH-3 (Sea king) and it has things like tacan switches to select but I just get a DME reading. 


Is there anyway to change the radio in the sea king in XP?
