Question about TACAN fix and position marking

[Alphabet_Ghost]

Manual say:

The SURF TGT position of

the TAC DATA category may be used to mark the position of

a pulse radar target, a visual target, or a TACAN station for

display on the TID.

 

But i tried position marking via TACAN fix , i can't create a SURF TGT over TACAN station when i never enter it befor .

(Start game in air and select SURF TGT - TACAN FIX - FIX ENABLE , I didn't even seen it appear in the TID .) I tried tacan fix again , it's worked ( SURF TGT - TACAN FIX - FIX ENABLE) . looks like it can't appear in TID or in right position at first time you enter it (pulse radar , visual target work fine) .

 

My English is no so well

Thanks
