primus_TR Posted September 15 Posted September 15 (edited) I can't seem to have a reliable positive response when I interrogate a friendly aircraft. On the the upfront panel, I have the IFF on (indicating XP), I bring the radar cursor over the track, SCS depress followed by SCS right. on the AZ/AL format, I can see that the interrogation is executed (vertical green lines appear around the track). Sometimes the friendly aircraft responds correctly, but sometimes it does not. The only way it seems to reliably perform a friend/foe interrogation is to STT the target. Only then I can get a reliable friend response. Hornet should be able to perform IFF interrogation without an STT (like in the F16, and even the F4E), so what am I doing wrong? Any advice would be greatly appreciated. Edit: Here is a track file depicting the problem I'm having. F18 IFF issue.trk Edited September 16 by primus_TR Added track file
Tholozor Posted September 15 Posted September 15 You can also enable automatic interrogation from the AZ/EL page with the AUTO INT option in the lower left corner.

When I turn it on, it gives the same result: sometimes works, other times not. I'll record a track later today to better describe my issue. Am I the only one who has this problem with interrogating friendlies?
Muchocracker Posted Friday at 05:02 PM Posted Friday at 05:02 PM When AUTO INT is turned off interrogations will only be run on the L&S automatically. But if you're setting the friendly as L&S them there may be an issue with outside of STT. Will do my own testing. I do have to ask tho, are you playing with Link-16 not turned on? This would be the only time a problem like this would turn up for friendly aircraft that i see.

In the track, I demonstrate both L&S automated interrogation, AUTO INT automated interrogation, and manual interrogation. The result is the same in all three cases: friendlies do not reliably respond positively to F/F interrogation. As regards Link 16, yes it is on (you can take control during track play to confirm), although I suspect IFF should be able to operate independently from Link 16. Or am I wrong?
