In Lightning / Buccaneer days, the only TACAN information available to the pilot in A/A mode would be range to the other aircraft's TACAN.
The Gnat TACAN was marked BRG and BRG/DIST.
I can't remember whether TACAN range is available with the mode selector to COMP - the range arcs are not shown in this mode.
Various other trials and installations offered more, but generally only A/A range was available in fast jets.
