Title: JABO Gun Sight
Post by: Minotaur on October 20, 2000, 12:30:00 PM
I have been developing a gun sight and here it is. IMO this gun sight is fairly good for all applications of JABO, Fighter, Buff Gunner and Ostwind Gunner.

The horizontal, vertical and diagonal lines allow BUFF and Ostwind gunners to predict lead a little better.  The lower vertical line is a ladder for use in "high zoom", helpful when adjusting range in the Ostwind gun.

For Fighter and JABO, the sight sets up like a funnel.  Much like the funnel used on modern day fighter A/C via the HUD (aka F-16).  Track your target into the top of the funnel and fire in between the two vertical lines.

For JABO I have placed two tick marks on the lower vertical sight line.  The upper tick mark is very close to the rocket release point and the lower tick mark is the release point for bombs.

Place the upper tick mark on the center of your target.  Place the lower tick mark on the far side of your target.  These ticks are dependent upon dive angle, but work fairly well.

Another very helpful hint that I just remembered...

When attacking a base I often go into a "Clipped View Mode".  I call it my "Attack Mode".

After you have hit and have destroyed a structure it starts to smoke.  This smoke really eats up frame rate.  By going into "Clipped View Mode" I can gain usually around 10fps in my frame rate, which really helps out a lot.  I have a toggle macro set-up on my joystick to do this.

The default key strokes are:
If I suspect smoke will appear or the base is heavily defended I toggle into "Maximum view clipping range".

Good Luck!     (http://bbs.hitechcreations.com/smf/Smileys/default/smile.gif)

NHMadmax;

Very sorry...  I am a Internet Dweeb, such things such as setting up a file for download I have no clue how to do.

You can still get this gun sight by doing this:

Maybe this will help.

Let's start with Mino's gunsight:

 (http://www.doitnow.com/~alfakilo/d.jpg)

I've labeled the lines to show his intent. The sight is used for both A2A and A2G. The flight path alignment lines are used to help the pilot get his gun line into the target's plane of motion (flight path). The pilot aligns one set of the lines with the target's flight path. This technique works just as well for the ack gunners.

 (http://www.doitnow.com/~alfakilo/e.jpg)

As for A2G, in the real world, the pilot must aim his aircraft past the target and then fire when his aiming reference reaches the target.

 (http://www.doitnow.com/~alfakilo/a.jpg)

It seems this is what Mino is trying to do with his rocket and bomb 'tick marks'. These marks are 'below' the pipper. I presume the pipper is meant to be used as a flight path aiming reference. The pilot would then aim the pipper to the target's 12 o'clock and hold it there. As he dove towards the target, the 'tick marks' will appear to move 'up' to the target. The pilot holds his pipper steady and waits for the appropriate tick mark to reach the target...then he releases the weapon.

NOTE:  This will only 'work' if AH ballistics are programmed to replicate real world ballistics.

For A2A use, the sight includes two vertical lines referred to as a 'funnel'. These are to be used to estimate the gun bullet stream. As the rounds emerge from the pipper, they will 'fall' below the pipper as a function of gravity drop and G load. Since the 'funnel' represents bullet position, then Mino is giving you a visual reference to fly the target into to get it into the bullet stream.

 (http://www.doitnow.com/~alfakilo/c.jpg)

Hope this helps.

hey thanks mino for that gun sigth  (http://bbs.hitechcreations.com/smf/Smileys/default/smile.gif)
and andy for those great graphics  (http://bbs.hitechcreations.com/smf/Smileys/default/smile.gif)
I have a question:

what's the best angle for dive attack??? of course using the mino's gunsigth:
45 degrees more??? less???

best alt from target to drop the salvo???.

do you have a film "mino" anyone else? showing ground attack with this gunsigth? can you post it??? specially tank's m-16's  (http://bbs.hitechcreations.com/smf/Smileys/default/smile.gif)
 
Im flying the f4ud to ground attack

any help will be appreciated

Thanks Andy!

I was going to whip something up last night, but it was "Guts and Glory" night on The History Channel.  I think you did a better job than I could have.

Terracota;

I will see what I can put together in the way of screen shots to show good target to sight relationships.  

The AH film recorder does not record rocket and bomb hits correctly.  The bombs seem to drop straight down and the rockets always hit long.

In all honesty, I am not really sure of my attack angles.  The reason that I say is because I initiate my attacks from a fairly vertical aspect.  Say 70-80 degrees when I roll into the target.  When it "feels right" I pull the sight up into the target, as Andy describes.

Initially, I position the target between the upper two diagonal lines on the sight.  In between and above the two heavy vertical lines that Andy labeled "Funnel".  Basically, the upper part of the sight.

Now I get my A/C in a stable dive and line-up the target to the thin center vertical line.  Once I get lined up I will start a gentle pull into my target, keeping it lined up on the center vertical line.

If I am using rockets, I pickle when the tick mark that Andy labeled "Rocket Pipper" is on the center of my target.  When using rockets I might stabilize the "Rocket Pipper" on the target for a up to 3-4 seconds.  Depends if the target is shooting back or not. This stabilization on target gets me closer and increases my chances of a hit.

If I am using bombs, I pickle when the tick mark that Andy label "Bomb Pipper" has crossed over and is on the far edge of my target.  For bombs release I do not stabilize on target like with rockets, but maintain a gentle pull through the release point.

If I am using guns, lets say to kill an AAA. The two heavy vertical lines that Andy labeled "Funnel" get really important.  Basically, I put the AAA even with the top of the two Funnel lines.  When I feel I am at the right distance I simply pull the AAA down through the Funnel.  Often times I can not see the ground strikes of the bullets, but rely totally on the sight.

Much of JABO is feel and practice.  I am by no means expert, but I will see what I can do in the way of some screen shots.  

Good Luck!   (http://bbs.hitechcreations.com/smf/Smileys/default/smile.gif)

well thanxs mino for the help, but I have a problem here I dont now why but I tried your sigth the last nigth an looks horryble  (http://bbs.hitechcreations.com/smf/Smileys/default/frown.gif)
in my f4u1d cockpit I tried in other planes and looks fine but in my loved plane looks to small and the lines looks like break  (http://bbs.hitechcreations.com/smf/Smileys/default/frown.gif)
anyway I now this is a problem with the sigths in the f4us no your sigth , I will have to back to my old sigth ;(

Terracota;

The next time your fly the F4U try resetting your front view and head position.  First press < F1 > then press < Home >.  These are the default keys, but should reset your view and head position to the AH default.  

If your viewpoint moves, this is your problem and you can then save this by pressing < F10 >.  For some reason the sight loses intensity and shape if it is not perfectly centered.

That's the way reflector gunsights work.  It isn't a bug.  (http://bbs.hitechcreations.com/smf/Smileys/default/smile.gif)

OK!   (http://bbs.hitechcreations.com/smf/Smileys/default/smile.gif)

Was their a provision for the pilot to adjust the gunsight to fit himself?

That quote is a little misleading.

The gunsight glass is really a mirror that reflects a light image that is created in a device located in front or above the instrument panel. It is fixed and is non-adjustable.

In some gunsights, the image consists of several parts (a pipper and a moving range scale, for example). These images are created separately and then combined when the images are focused on the gunsight glass. For this reason, this gunsight glass is known as a 'combining glass'. (At least it was until HUDs came along...fledgling fighter pilots these days have never heard the term...in my time, that's what it was always called!).

This image is focused at infinity and is projected straight back into the cockpit. The pilot has a reasonable amount of head movement freedom (an inch or two at the most, side to side and up/down). Also, since the seats in most fighters are adjustable to accomodate pilots of varying heights, the sight display is unaffected by seat height position.

The optical purity of a combining glass is amazing. You can look thru it from straight on down to practically sideways and still see thru it with no distortion.

Re: gunsight reflectors/glass/combiners

I have a K-14b sight which uses a clear plexiglass reflector.  There is no detectable distortion through the angled plexiglass.  

This unit, btw, is actually two gunsights in one head unit.  The center of each of two projectors are the same distance apart as our eyes.  The right eye sees the ranging diamond and pipper.  The left eye sees a small center cross and a 70 mil circle (where the circle can be blocked with a lever on the left side of the sight head). Both projectors can be operated independantly or together.  

Each image is focused at infinity but neither appears as a 3D image since both are not combined.  There is a very interesting effect that happens, however.  When one eye is closed, the other sees an image on the left or right side.  When both eyes are open, both images appear to move to the center of the reflector without changing the aiming point.  In fact, its not even possible to photograph both images together since the camera is essentially acting like one eye. Also the size of the image does not change with distance of your eyes from the sight head.  Moving closer to the sight has the exact opposite effect that we see in AH (where moving your head closer zooms the image)- the image appears to get smaller in relation to the gunsight and reflector unit.  Moving away
makes the image appear to grow in relation to the gunsight head and reflector unit.  The size of the image over target, however, does not change with head movement.  ( Ex - Imagine being  parked several hundred yards from a building in your car.  Moving your head closer to the steering wheel makes the wheel appear bigger in relation to the building but does not change the size of the building.)

There is no ground attack reticle image in the K-14b and this is/was the standard installation in the P-51D.  It features the standard fixed circle/cross and the moving diamond/pipper.  The diamond image used for computing lead is ingenious in its function and design.  You set the the target's wingspan (in feet)on the up front span lever.  The rotating throttle handle is turned (like a motorcycle grip), causing the diamonds to expand or converge around the center pipper. This allows the pilot to fit the targeted airplane within the diamonds to determine range.  Using a gyroscope mounted mirror, a mechanical computer in the sight head computes the range and corrects for ballistics and G-load to move the diamond sight around the field of view.  The pilots maneuvers the airplane so that the sight appears to sit on the target for more than two seconds (basicly a steady state gunnery solution) then fires for a high percentage shot.  If you want to see how it works, fire up the brand AW sim and enable the computing sight.  Heh, one of the few things the sim actually modeled correctly.
