[ALREADY REPORTED]Neutral IFF BUG

[Joni]

When interrogating a neutral coalition contact with an AWACS present it shows ambiguous both in top and bottom HAFU (correct). After a while it turns into a hostile top HAFU and bottom ambiguous HAFU (incorrect) when it should remain double ambiguous.

The bug happens when the neutral contact is set as L&S. If a different one is set as L&S then it goes back to double ambiguous brackets.

Please don't hate me for the spam, I just discovered that the bug exists for anything that is set as L&S and doesn't reply to mode4. No matter if is neutral or enemy, it will always show enemy red chevron HAFU if set as L&S.

I don't know if it helps, but I saw that turning NCTR off solves the issue, which is strange since the tests I conducted were cold aspect (in track attached as well).

 

What also draw my attention was the fact that the NCTR print isn't working, it does't show the type in SA page.

 

So NCTR is actually contributing to the IFF (during cold aspects too) but it isn't showing what type of print it gets.

 

It would also be good if NCTR didn't recognize a passenger aircraft as hostile.

 

 

Thanks.

See this:

tl;dr the NCTR part of the ROE matrix is bugged since the beginning and doesn't need STT.

I don't know if this has anything to do with NCTR marking neutral coalition aircraft as hostile. It shouldn't do that, anyway.

Seems like the NCTR part needs some work, with respect to which aircraft it recognizes as hostile, now it magically knows. I tested with a Blue Hornet vs a Red and then a Neutral Hornet. Both the Red and the Neutral F-18s were flagged as hostile by NCTR. A Mode 4 IFF interrogation gets no reply, so they're marked as Hostile. The current ROE matrix without donors is supposed to be "No/Wrong Mode 4 IFF response + NCTR hostile print = Hostile". How does an F-18 get marked as hostile by NCTR, when it could very well be a friendly F-18 with its IFF transponder off? There should be aircraft that are marked as hostile by NCTR and aircraft that are not, regardless of coalition, at the very least other Hornets.

I'm ok with all of this, otherwise it would not work nicely, I think ED made the right call on that aspect. 

 

NCTR with STT shows the correct type of print picked up in SA page, with no STT it just contributes to the ROE picture but doesn't show print. This needs to be corrected.

 

On top of these, I think the first thing to address is the fact that NCTR makes a neutral coalition hostile. Then they can work on the broken part of NCTR itself (angle, L&S thing, etc.)

 

This is my opinion though, I just hope this thread was useful at least.

 

Thanks for the other thread link, I didn't find it before.

 

 

Thanks.

Hi,

this is covered in another report, AWACS are reporting Neutral aircraft and will ID them as hostile when declare is used on NCTR 

 

Thanks

Thanks.

 

On FC3 aircrafts, neutral are showing as enemies. No NCTR or awacs.

 

Maybe it helps.
