Machalot Posted July 16, 2020 Posted July 16, 2020 (edited) A couple times today when I tried to setup my TACAN, the DED showed "TCN ON" in the upper left where it would normally show "TCN REC", "TCN T/R", or "TCN A/A T/R". Flipping the dobber to the right has no effect. Entering a channel and hitting enter has no effect. This only happens sometimes. I have tried power cycling all the avionics systems including MIDS LVT, but no improvement. Am I forgetting a step or switch setting somewhere? Edit: Solved. See post below by Gattling. Edited July 22, 2020 by Machalot Update that thread is solved. "Subsonic is below Mach 1, supersonic is up to Mach 5. Above Mach 5 is hypersonic. And reentry from space, well, that's like Mach a lot."
Machalot Posted July 17, 2020 Author Posted July 17, 2020 (edited) I put the INS in NAV once it finished aligning. Why should it be in NORM? I did a stored heading alignment and then set it to NAV. I just tried moving it from NAV to NORM and it made no difference, it still shows "TCN ON". When I start up a new jet with NORM align it seems to activate TACAN just fine. Don't know why that would be the case. Edited July 17, 2020 by Machalot "Subsonic is below Mach 1, supersonic is up to Mach 5. Above Mach 5 is hypersonic.

Florence201 Posted July 17, 2020 Posted July 17, 2020 It appears the stored alignment might be bugged then, if you get good indications from a full alignment. Other than that, are random failures on? [sIGPIC][/sIGPIC]

Machalot Posted July 18, 2020 Author Posted July 18, 2020 I'm pretty inexperienced with track files. I know multiplayer records them automatically, so I must have it recorded. What would you want to see, the whole file or an excerpt? "Subsonic is below Mach 1, supersonic is up to Mach 5. Above Mach 5 is hypersonic. And reentry from space, well, that's like Mach a lot."
mahuja Posted July 18, 2020 Posted July 18, 2020 TACAN should not rely on your INS in the first place, so how you aligned your INS should be completely irrelevant. One thing to watch for is if you have turned it off in the volume controls panel.
Frederf Posted July 18, 2020 Posted July 18, 2020 TACAN volume knob doesn't have an off position in this model F-16. TACAN is handled by the overall datalink system I guess because it shares antennas or transmission deconfliction or something. I don't think TACAN function requires INS alignment even though other DL functions do.
Machalot Posted July 19, 2020 Author Posted July 19, 2020 Well today I proved it is not related to the INS alignment because I did a Stored Heading Align three times, and I had a glitched TACAN the first time but not the other two times. I do have a track file and the TACAN glitch happens in the first few minutes. It's a huge file though, is there a way to cut it down and post it here? "Subsonic is below Mach 1, supersonic is up to Mach 5. Above Mach 5 is hypersonic. And reentry from space, well, that's like Mach a lot."

TCN has nothing to do specifically with the INS alignment procedure. Check your key bindings for the C&I knob. TCN ON will be written if your C&I knob is moving to BACK UP position (it should be at UFC position) due multiple key bindings or inadvertent selection. Hope that will solve your problem.

That solved it. Thanks! :thumbup: It wasn't a keybind issue, it was just me being absent minded after using the backup UHF to ask the tower for permission to start up. Just out of curiosity do you know how to operate the TACAN in backup mode, or know of a source on it? Or is it even modeled? "Subsonic is below Mach 1, supersonic is up to Mach 5.
