I was curious; do F-16C Block 50/52s still have the EEGS as standard, or did they go back to the old pipper system?

Ah. :D Someone told me that he'd heard that pilots were dissatisfied with its performance and that they were considering switching back.

As I understand, the EEGS is a fine gunsight, but not as good in most aspects as the old snapshoot-piper gunsight.
The problem is, not all of the new blocks have both sights, some have only got the eegs so you cant switch back even if you want to.
As I recall, the old snapshot never missed a victory in real dogfights (lebanon war).

Cheers.

They stopped "shooting the dart" (strafe dart towed by another aircraft) because the eegs was too good. You shot the dart off the first time, everytime. Having used both for a while (the new T-38C started out as snapshot/LCOS, now we have EEGS) the EEGS does a much better job of establishing plane of motion and range without a radar lock.

that's true cylon...
Is the EEGS ever been used in a real conflict? Snapshot might be combat-proof but the EEGS just is a damn good system...

When did the last gun kill happen at all? Most likely before EEGS existed
Where is that switch in the cockpit? If that is not OPSEC of course

As I understand it, EEGS is the default setting for your guns. At least they are on the Block 52s the RSAF flies. You can switch back to LCOS if you want to through the SMS page.

I think the EEGS is a great gunsight, it just takes a good PAI to teach you how to employ it and you'll realise it's alot better than snapshoot LCOS.

As long as you aim with the bore-cross (establish plane of motion), you can't go wrong either way. The bore-cross is the only "control" instrument in the hud. All else is performance instruments...

O.K,
got the info from an IDF/AF test pilot /I.P (hope thats a good enough):
EEGS has a 0.5 to 1.5 second lag, when an aircraft you are trying to shoot is changing his plane of motion
(barel roll or such) then you have no real way of aiming (even if you try using the aded MPL symbology)
thats why the EEGS is so good in shooting the dart (the dart does not change its plane of motion) and
so bad in shooting aircraft that are trying to avoid you.
snapshot doesnt have this problem, as cylon wrote " aim with the bore-cross" the snapshoot is the extention of the bore- cross! so you are actualy using the best way of aiming. instead of counting on
a cumputer with lag problems (EEGS).
as I understand this is the reason many IDF/AF pilots still fly with the snap insted of EEGS.
Cheers,
FEZ.

You have an entire bullet time of flight to re-establish plane of motion once the bandit has changed it, regardless of eegs or LCOS. No site (without a radar lock) predicts new plane of motion prior to the bandit changing it... Eegs will tell you potential.... (whiskers) and even that is based on a max maneuver potential assumtion.

In other words both eegs and LCOS are historic sights, not predictor sights.

Probably better that way. I think a human mind will be better in predicting future actions of the other guy then best software.

They both predict lead required, but not plane of motion... EEGS does a better job of displaying predicted lead for bullet time of flight.

I ask a Pilot from Blk 50 (He was flying Blk 30's in the past)and he told me that with the EEGS(Engchanged Envelope Gun Sight) is much more easier to aim the target.

As far as I know, Blk 50/52 posseses both EEGS and LCOS/SNAP aiming modes.

As someone has said above, EEGS is great even if you don't have locked-up the target with FCR. On the other hand, SNAP mode is useful when you're expecting taking a quick snapshot or if the target is changing the above-mentioned plane of motion faster than the EEGS is able to "realign" itself.

Also, when using EEGS, do not forget to adjust the funnel when expecting targets with bigger wingspan than usual.
