I cannot get carrier TACANs to work. This is true for the Heatblur Tomcat F-14, the Asobo F-18 and the old Touching Cloud F-18 mod. I know how to use TACANs and have the land based TACANs work in these fighters. However with the static carriers from the Miltec Supercarriers addon and with the included carriers of the Heatblur Tomcat no TACANs can be tuned. This is also true after uninstalling the Navigraph Navdata and using the sim data only. With empty community folder except the Tomcat and its included carriers it is the same. Adding in the Supercarriers and the F-18 there is no change. This is on sim update 15 beta. I have no idea if this has ever worked in SU14.
It’s been awhile, but I remember only US Airfields/Airports being able to make use of these channels.
I am speaking of US loctions. Did not test in other regions.
