Are you saying that the frequency associated with 25Y is wrong or that the database has the wrong frequency? I can fix the former, but not the latter. > Do you have any idea what magic incantations are required to equip an > aircraft with TACAN? It shouldn't be too hard to equip my (OK, mostly > David Culp's) OV-10 with a TACAN receiver once I figure out how... Well, I ought to ... I wrote the code :-) Look in the seahawk directory. Look in systems/ . You need to add a similar file to seahawk-instrumentation. This provides a non-default set of instruments, and includes the tacan. You then need to amend the -set.xml file to include this. Finally you have to ensure that there is electrical power to the instrument. TACAN is a normal instrument, and this procedure is the same for any such instrument. HTH, get back to me if you have any problems.
