The new gun sight for the F-16 and F-15 is called EEGS. EEGS (pronounced as it is spelled) stands for Enhanced Envelope Gun Sight. The EEGS funnel allows the pilot to match the wingspan of the target with the width of the funnel to determine the proper firing range. The other important gun aiming cue in the HUD is the gun cross. The gun cross represents the departure line of the bullets. You can consider the gun cross as the gun barrel. Bullets pass straight out the gun cross.
So, how do you use the funnel? The gun in the F- 16 is boresighted to 6 mils. This means that the gun is adjusted to fire a burst that will put 80% of the rounds inside a 6-foot diameter circle at 1,000 feet. This is a tight pattern. You can have either a highly concentrated burst that completely misses the target or a very lethal burst that vaporizes the target. It just depends on the quality of your gun sight (and your ability to aim it.) Air-to-air situations are always dynamic, and targets under attack will normally jink violently to stay alive. Since the sight (and your reactions) are not instantaneous, it is likely you may achieve a highly accurate miss; that is, a tight burst that finds only empty air. The sight was lined up and stable, but you missed. How could this happen? The sight was lying because the target was jinking faster than the sight could react. The way to overcome this problem is to strive for an inaccurate hit. You do this by using the EEGS funnel to fire a burst while moving the target through the area of uncertainty. The EEGS funnel gives you a perfect solution when the wingtips of the target match the width of the funnel. If the target is jinking, however, this "perfect solution' may be in error.
Here is how to use the gun cross / funnel combination to kill the bandit:
Place the gun cross out in front of the target. Picture the target with a long pilot boom sticking out the nose. The gun cross should be placed on this extended pilot boom. If the target changes his plane-of-motion, then fly to place the gun cross on the new position of this imaginary pole sticking out of the nose of the target.
Next, over lead the target by making the wingspan of the target extend past the funnel. This will place your bullet stream in front of the target's nose.
Fire the gun while easing up on the G. This will move the target from the bottom of the funnel to the top. Cease fire when the target's wings are inside the funnel.
Make a slight jink out of the bandit's plane-of-motion so, when he blows up, you don't suck a body part down your intake.
This technique uses the gun cross and the EEGS funnel to place the bullet stream in front of the bandit. When you ease up on the G, the target should fly through your bullets.

Что такое "the area of uncertainty" то? Разброс и есть. Написано же ясно: запиxни крылья самолета (цели) внутрь воронки разброса, да стреляй.

Чем шире воронка прогноз-дорожки, тем ближе цель. Это прекрасно видно и в предлагаемом кино, виражат в двух кругах - еврофайтер в большем, ф-16 в меньшем, и по касательной из меньшего круга полетят снаряды. Видно же отлично, чем больше зрительно цель, тем шире прогноз-дорожка относительно размаха крыльев цели. Ф-16 догоняет и обгоняет по угловой скорости еврофайтера. Все из-за того, что время виража меньше.
