Using the EOS on a Mig

[Maulkin]

How do I use the Electro-Optical system on a Mig to perform a sneak attack on a target? I assume you have to use a heat seeking missle for this tactic? Dont the Su-33 and Su-27 have similar EOS 'bubbles' in front of the canopy or is that something else?

 

I am just full of questions :).

First of all make sure your radar is off, obtain visual contact with the target and push 5 to select EOS mode. Place target in the circle, use view keys or trackir to move circle onto target and hit TAB to lock.

1. Press O if you are using 1.02 for EOS scan.

2. Ill assume yes since it is a heat seeking sensor used in them type of warheads.

3. Yes the Su-27/33 and Mig-29 have the EOS. That little bubble is exactly what it is.

How do I do that? BTW I am using Flaming Cliffs 1.1 version.

 

The FC manual says the following about the Close Combat Mode I think you guys are referring to:

 

This unique mode is useful for manuvering combat, and selected with the [5] key....The HUD display switches to Attack (STT) mode after locking the target.

 

Doesn't STT mean Single Target Track and that means the radar is emitting? I assume I have to ensure I have an infrared seeker missle is selected (like the R73) to prevent accidentally turning on the radar?

 

I assume the CCM can be used with short/medium range radar active/semi-active seeker missles?

Maulkin,

 

To use EOS (V1.1), proceed as Hitman_214th recommends. Selct A2A mode with the "2" key. Press "O" to turn on EOS. When in range, a target marker will appear on the HUD (as it does if radar is used, instead). Move the targeting cursor over the target marker and press "TAB" to lock.

 

It's not a problem if you have a radar-guided missile selected. The radar does not turn on when EOS is used in this manner. Radar-guided missile are unlaunchable. Select an infrared guided missile and, when launch parameters are met, you will get a launch cue. If you are attacking from someone's 6, they'll never know what hit them.

 

Edit: Actually pretty cool to launch and kill a target this way, have the target break up, and watch the multiple contacts on the HUD as the pieces rain down from the sky ahead of you.

Well, to the left of the HUD there should be a vertical line of Cyrillic letters. Or not Cyrillic letters, if you've got the English HUD on . . . . anyway.

 

There's one letter when your radar is on, and one when the EOS is on. If both are on, both letters are displayed, one above the other.

 

I don't have a Russian keyboard, and can't remember which letters mean which anyway . . . . but I think it's the Russian "I" for radar, and the Russian "O" for EOS.

 

 

You see how this helps determine whether radar or EOS is turned on? ;)

 

 

Truth be told, you can use the EOS in any A/A HUD mode. You just get limited range and functionality.

 

Helmet mode is probably most effective, but BVR mode, Vertical Scan mode and Boresight work just as well - Longitudinal Missile Aiming mode just aims using the missile seeker head, with no airframe-mounted sensors required.

 

 

STT does NOT mean the radar is turned on. You can maintain a lock purely with EOS.

 

If you have a lock with EOS, the radar won't come on if you lose lock (the radar will only try and hand-off to EOS if you lose a radar lock, not the other way around) and you will be unable to select a radar guided weapon - you'll only be able to cycle through any heat-seeking missiles you are carrying.

 

 

Just to confirm, you can use any A/A HUD mode with either EOS or Radar.

It's up to you whether you use either, or both.

If you're using the radar, you can use any CAC mode to fire a radar-guided missile . . . . . sometimes in a dogfight the enemy will be shooting flares like there's no tomorrow but flying relatively straight and level, in which case an R27 is a relatively guaranteed kill if you happen to have one left - won't be affected by flares and it has a nice big warhead.

But keep that quiet ;)

 

 

Sneaking up on a target isn't always practical - and an IR missile Will Not Launch until the seeker head itself has a lock on the target. It's possible to have an STT lock on your target from the airframe-mounted sensors, be within the missile's kinematic range (i.e. the missile has the energy to get to and kill the target), but still be unable to fire, purely because the missile can't see what you want it to shoot at.

In case you're wondering, this is since no IR-guided missiles have a datalink allowing the launch platform to guide them to a place where they can see their target - if they did, things would be rather different.

 

In terms of getting a seeker lock . . . . there was a nice diagram in the Flanker 2 manual (which I think they reproduced for the FC manual) showing the seeker lock range for a normal target. Very low range from the front (not much heat produced around there), quite a long way from behind (nice hot engines to look for and kill).

 

This info of any use to you?

[SUBS17]

As soon as you take off just push 5 and you're instantly in EOS mode(with radar off) in Mig29,SU33/27 in FC. No need to push anything else, look at your target, place him inside the circle and push TAB to lock. Try it in a single mission using R27ETs with AWACs, very cool. Or alternately try it against a C17 transport. Very cool.

One last thing to point out, eos does NOT know friend from foe, it cant tell enemy heat from friendly. Make sure you know what your shooting at. Unfortunatley, the only way to tell iff is to turn the radar on unless I am mistaken.

Wow this is a tonne of info! Thanks alot fellas I need to go home and try this stuff out. I have used the Helmet Mounted site (key '5') but it seemed to work for all kinds of missles and I was worried that I had my radar on and didnt know it.

 

So the 'T' in the above picture (left side of HUD) means that EOS is active? What is the symbol is radar is active?

Note that it is possible to have radar on in all these modes. Also, if you start to lose heat lock with eos, your radar will come on to compensate, which will give the game away.

[Maulkin]

So is there a light or something to tell me if my radar is emitting so I know if/when my target is now aware I am sneaking up on him, sort of like the ECM light that tells me I am currently a radar emitting becon? Sometimes when I am switching between submodes I think some of the modes automatically turn on the radar. For example if I accidentally switch to flood/boresite mode with a semi-active radar seeker selected. Is there a way to turn off the radar and keep it off no matter what?

a backwards "N" indicates radar is transmitting

 

I would like to re- emphasize the lack of IFF when using the IRST/ EOS. It's very important when flying online to be able to use this system correctly. You can toggle radar on & off and look for an "F" symbol on the left side of the HUD indicating a friendly lock. One system automatically backs up the other in the event you lose track of a target. If you're flying into traffic with both hostile & enemies present- you may lock one of your own.

 

ALL contacts have "HOSTILE" symbology when being tracked by IRST/ EOS
