Here’s how I plan to test. Set at civil plane in a slow orbit or turn to 90 degrees. Set to no reaction to threat. Should allow me to figure out if it’s modeled yet. Yeah, basically the rules are, it will default to the mode you use as primary sensor (whatever what is shown on HUD) atleast at first. If it loses lock and secondary sensor picks it up then the previously secondary sensor is now primary. If the original primary sensor can re establish lock it will become primary again. Only real exceptions are Laser range, when it can range laser often radar will become primary as it is now longer needed for ranging pulses and goes STT. Or OPT/Helm, where the first sensor to lock becomes primary. You can see this now where if you lock within 30 degrees of nose often IRST locks first, and radar if beyond that limit. If you say locked IRST first, you will often see it transfer to radar primary beyond the 30 degree limit of IRST, but when the target goes back within the 30 degree gimbal limit of IRST the IRST becomes primary sensor again.

For KMGU, only the first “packet” drops on the pipper, and every other packet will drop after. So you will need to aim short to have all your submunitions land equally in front and behind the target even if things work perfect Of course in training mode doesn’t matter as it will only drop one “packet” at a time

I still have yet to test if being 5 degrees below enemy turns off notch filter yet Being in COOP 5 degrees low where radar doesn’t have notch or same speed filter, IRST good view, basically no hope for them to lose lock the only weakness for COOP i can really see is if they notch radar and flare the IRST at the same time. But obviously keeping that on the down low

Are you sure it has up and down positions. My interpretation is the gun trigger is the only folding trigger (thus first and second detent)

Almost every manual says the bottom position shouldn’t be used or has no function. German manual describes it identical to top position yet “narrows the jamming strip.”

Target altitude still shouldn’t need to be set, and you can always compensate for wind with pre designation.

Move AP/AJ switch up. Makes a huge difference, many manuals suggest to just always fly with this switch up

Alright, either COOP is fully implemented, or one step away from it Helmet is now a beast. Since radar has such higher gimbal limits then IRST, you can get sensor lock up to the full off boresight range of R-73 and R-27. And then once you get that sensor lock your radar will maintain with the +/-70 degree gimbal and -45/+60 degree gimbal. Your IRST is flared or out of limits radar picks it up perfectly. They fall into +/-50 kmh gap of radar then IRST picks it up perfectly. Very nice. To clarify for those that use it: To fire Fox 1, Radar must be primary sensor. I.e, it must be the sensor displayed on the HUD (RL/RA). If Fox 1 is already in the air and HUD changes to IRST primary sensor (TP/IR on HUD), Fox 1 will guide fine. IRST can pick up radar lock easily whenever coop is on, but for Radar to pick up lost IRST lock requires A. In Radar mode and IRST has already previously picked up lost radar lock. In such a case if IRST loses lock Radar can regain it or Radar will naturally become primary sensor as soon as it can regain full lock again (such as when enemy exits notch). B. For IRST modes, Radar cannot pick up lost IRST lock if Radar is only ranging or attempting to range. You must see Radar diamond (STT) while IRST is primary sensor (TP/IR on HUD) for it to pick up lost IRST lock. Each mode is a little different: -In IRST search, it will use Radar to range until laser can pick up the target within 6.5 km at which point Radar goes STT. So until that laser ranges and Radar goes STT a lost IRST lock will not be picked up by radar. However you can prevent this by pressing lock a second time at any range to force Radar to become primary sensor and STT, also allowing you to fire fox 1. -In IRST vertical scan, it has similar logic except that Radar cannot find target until within 10 km, and will not show range during radar ranging. So requires laser to range or lock button pressed 2nd time for Radar to fully support IRST. -In IRST OPT/Helm, like vertical scan outside 10 km the radar cannot help you. But once inside 10 km it will go STT for full support. AFAIK, the only way to positively IFF is still to use radar mode for lock first, then in COOP move knob to IRST mode when you believe IRST to be in range to lock. Only then can you change radar power from Illum to dummy for coop to properly work in IRST modes after IFFing the same target.

Ahhh thank you!!

Combat employment claims it moves on same +/-45 degree vertical scale as missile aiming circle.

I don’t understand. Aren’t those just the normal boresight indicators for IRST or radar lock? Unless you mean it simply puts a circle around the center crosshairs until 1600m. That diamond, it has to move up and down on 45 degree scale. There is no other way I can see

I mean you are lowering the gun trigger. The whole idea is the circle is there to line up the crosshairs which will appear once within effective gun range. Here is a quote from combat employment, I was mistaken the symbology change is at 1200m ”At a target range of less than 1200 m, the information on the ILS will change to the "NSVV" mode indication (Fig. 55)” We were unsure before if it meant perhaps just the crosshairs with range circle and not the target circle, but I guess this is our answer.

The combat manual claims that symbology should only change to gun mode within 1600m. So need to line up gimbal limit indicator (diamond for radar and circle for IRST) in the center of the display to see approximate location just like a MiG-21 with a HUD now

Did you try within 1600m?

Interesting. I did find something in manual that could be a cause for this as well ED manual says that if SPO-15 sees a CW signal and a LPRF (category ‘C’) signal on the same azimuth, it is confused as a P category as long as both signals operate in same mode. I hear F-14 uses a second TWT for CW, idk about PD, and it was mentioned earlier about using LPRF to keep track during low closure rate. If PD can be manually activated, perhaps then we see what we see for other 4th gen’s, where we finally see a properly identified MPRF/HPRF “F” category. “If a continuous wave radar is detected on the same azimuth as a type С radar, and both operate in the same mode (search or track), they might be falsely identified as a single type П radar - the pilot must exercise their judgement to determine if the type П warning is legitimate or a false positive. If the type П is selected as priority, it prevents types Х and С from being displayed at all if present. If the two radars operate in different modes, the device has provisions to filter out false type П indication, so in practice this will only happen when both radars are tracking (as simultaneous illumination by both radars in search mode is unlikely).”

Makes total sense

You’re saying F-14 uses PD for Sparrow F/M/Phoenix illumination, AND the RIO/AI can flip a CWI switch, correct? Unfortunately don’t have many friends flying the F-14 lol

They are interested in doing it. They wanted to do it for R-60 for Hind but claimed they needed to wait for new FLIR model, but then new FLIR model came out and Fox 2s were unaffected becuase I bet it’s a really big job. I’m sure they will get there. KOLS was not designed to detect ground targets, regardless as you see in game it will see hot ground, water, tracers, flares, clouds. So it’s very possible you could not only detect but lock a ground heat source that had enough contrast, which would be needed because when locking KOLS an auto gain circuit turns on that requires the target to have enough “contrast” to be distinguishable from both the background and internal noise.

You do get a launch warning in the form of the P category for CWI pulse radars. No one seems to question INS realism on/off. We have it even for this module.

Makes sense! Thanks!!!! Do you know if this is for all locks or just during STT missile guidance?

Would’ve needed in cockpit and computer mods, but interesting it was added to the Cyprus variant but not Mi-35M lol

What is there to configure about the head down display?

I do wonder if 16x ATGM is an air show loadout or not. The original computer from Mi-24V-Mi-35M can only handle up to 8, which is why you see Mi-35M with 8x rack on only right wingtip so much. They have quad racks. But I also know the 8x rack has a winch to make ground crews more happy You say weight is a problem for modeling 24V, but this Cyprus/Serb 35P is already 300 kg lighter from fixed gear and short wing. But IMO, that is little FM work as it’s just moments that DCS naturally calculates into inertia.

Basically yes, but COOP doesn’t matter. You don’t need IRST to launch R-27T, it is just an IR fox 2 treated just like R-73 and R-60. You could tear the IRST from the jet and it wouldn’t stop you from getting LA with R-27T in radar mode becuase LA with R-27T only depends on seeker lock and in range. It’s just like any other fox 2, the radar cues the seeker head, when the missile can lock you get LA signal and can fire. No IRST involved. All COOP is doing in radar mode is picking up lost radar lock if it can. It doesn’t do anything for missiles except tell them where to point their seeker if the radar hasn’t already. Becuase you mentioned “shoot R-27T as soon as IRST has acquired” is why I said “the trick is knowing when IRST is locked,” becuase one COOP trick is to get radar lock, switch SUV knob to IRST mode when you are pretty sure IRST has lock. And lock will transfer from radar to IRST so you don’t warn the enemy RWR. If you change modes before IRST locks, the lock drops. You have multiple ways to aim a Fox 2, radar, IRST, Helmet, and Phi0. If you lock with Radar, you will get LA when R-27T locks on and in range. If you lock with IRST and no range, and R-27T locks, you will get flashing LA to tell you that you R-27T is locked but doesn’t know if it’s in range. If IRST locks with range from laser or radar, and you get solid LA, R-27T is in range and locked on. Same for helmet, if LA flashes the fox 2 is locked but doesn’t know if in range. Solid LA means missile is locked and in range. All fox 2s work like this.

I also wonder if it’s becuase P category was also often used for “Naval” radars as they were often CWI.
