Hornet hostile identification via NCTR + HAFU question

[Jak525]

Hey everyone - two questions. 1 - with the new rules of engagement in the Hornet, a hostile HAFU ident can only be assigned with both a negative Mode 4 response and an NCTR print or off board hostile identification. My question is about NCTR - what happens if a mission is set up where both sides have the same plane? I take it NCTR will just not contribute then?

 

2 - what is an "ambiguous" HAFU? When would we see it in the Hornet?

Great question. Theoretically NCTR should indeed not make a difference in that case, but I'm afraid DCS just doesn't care and it will work anyways :(

As I understand it ambiguous is the result of conflicting IDs, for example onboard marked as hostile and offboard marked as friendly, or friendly IFF return with negative NCTR (eg a mig29 returning an IFF response). Not sure if they are going to model that, if that's how it works.

That’s a very good question. I think it will be simply based on coalition.

Would be a shame if they didn’t model that. Could lead to some interesting encounters with Iranian F-5’s, F-4’s and F-14’s on the Persian Gulf map. Or a German Mig-29.

I mean, how would they simulate NCTR realistically anyways? It’s impossible. They probably code it like this: if angle < 40 deg and distance < 30 nm -> have the HAFU switch to friendly/hostile based on coalition. (Or something like that)

Yes, but instead of just basing it on the coalition they should base it on the aircraft type and check if that type is available on both sides or not.

A good, general document on NCTR:

Your coalition should be on a set IFF channel freq? If channel freq is different, would no response generate a foe?
