Convergence question
« on: October 09, 2014, 04:37:03 PM »
I have found myself shooting high over the target . Moving my convergence around doe's not seem to help but is that the right place to get my round's to drop down some ? Been missing to many easy shot's shooting over the target . Say in the Yak . ????

If you're putting your sight right on them and your shots are going high then that means your convergence is set too far out. You want to set your convergence at whatever range you feel most comfortable shooting at. If you like pulling the trigger 200 yards out then set your convergence to 200. If you like shooting at 400 yards then set them to 400. And so on and so forth.

Are you flying with combat trim on? As you are accelerating below 300 or climbing up slightly to a con, your nose will tend to hold higher sometimes than you can fine control compensate to hold it steady. ShVAK 20mm and B-20 shoot flat to 225yds and drop by 24 inches by 400. Setting for 400 will have you shooting high at 200 when you are level.

HiTech, this is why I keep asking you for all HUB cannon, and the La(s), to lock the guns at 0 azimuth which is historically accurate. Then everyone will be on the same starting page talking about gunnery with these planes. ShVAK and B-20 in Russian fighters then should hit .5 inch low at 218 yards (200m).

Yeah I have it on . I see what you are saying now . Thanks

Hiya Flench,
If you go into the offline mode and turn on the lead computed site, you can see where your bullets are actually going to go. It really helps to get the feel of where your shots are actually going compared to where you thought they were going.  Then, work on convergence and adjust based on the plane.
Try the training arena also, I believe that is still active in there.  I hit that setting offline at least once a year just to keep fine tuned, as I tend to spend more time in scenario design than I do in flight and I get rusty very quickly.

Ok Roc , That's just what I need to do . Seems like I can't hit a barn after I have been back . I don't remember how to turn it on ether .

Set your guns, regardless of plane or caliber, to 300 yards for all of your air to air fighter stuff.  Do not fire until the icon says 400 (or closer).

If your moving dirt or hunting bombers then stretch it out to 400 or 450 yards.

Remember, there are three other variables to think about when thinking of your firepower: rate of fire, trajectory, and velocity. Having a plane with all of the same gun like most US fighters (6/.50 cam MG's), or the Typhoon (quad 20mm), etc, really helps in zeroing aim and impact.  Some planes offer up THREE different calibers with three very different rates of fire and trajectories. The 190A-8 is the worst. I hears guys quite often complaining that the German 30mm from the 190A-8 "sucks" because they just ripped a guy from head to toe with X amount of hits and nothing happened. After a bit of enlightenment they learn they probably raked the target with dual 13mm MG fire and not 20mm or 30mm hits. The 13mm has a much flatter trajectory than the 30mm, and is still superior enough to the 20mm to make it noteworthy.

Anyways.... Im guessing that that like most people it isnt about the guns and it is more about the "time on target".  Enough damage has to be done to a specific place on the plane for the hits to matter. Keep practicing and just remember there are thousands of ways to butcher a cow that are "good enough", some ways are better than others.   :aok

You can't set this for the main arena or special events, it's just for offline practice and training arena.

Open your clipboard map.
Navigate through:
Options
Arena Setup
Environment
Arena Settings

Then, under the General Tab
Scroll down to Flight Mode Flags
Check "Lead Computed Gunsight"

Go fly and there will be a green floating sight out in front of you, that is where your bullets are going.

True, this is why when I'm leading fighter groups in a scenario tasked with attacking bomber streams, I always train my team to only aim for a specific wing on the bomber, enough passes and the damage accumulates and planes fall out of the sky :)

if you are shooting over the target by just a smidgen, try aiming just under the target, by a smidgen.

Using the Lead Computing Sight offline against the drones is misleading. The drones are flying between 225 and 250 mph. Computing lead depends on your ability to judge the following as primary conditions:

1. - Their angle of travel relative to yours.
2. - Their speed of travel relative to yours.
3. - Their range relative to you.

Between 45 and 90 degrees to your line of travel the 100mph principle is in effect. This is why most gunsights from ww2 are 100Mil in diameter. They are called 100mph gunsights. At a range of 1000ft(333yds) a 50cal or Hisso20mm will take 1\3sec to travel that distance. During that 1\3 sec, if your target is traveling at 100mph, looking through your 100Mil ring. Your target in 1\3 sec will appear to travel from the edge to the center dot or, 50Mil, or 1 radius.

This means for every 100mph your target is traveling, you lead him by that many radii or 50Mil(s). So 300mph you lead by 3 radii. This holds true from 45 to 90 degrees of your line of travel.

The offline drones are traveling between 225 and 250 miles per hour. So for calculating deflection they are under the 65mph principle or a 70Mil main ring is used. 225-250mph is roughly a lead of 3-4 radii with a 70Mil main ring.

I've tested the above offline and a 70Mil main ring using the lead computing green cross works like the WW2 manuals describe.

In reality, offline, the best way to use the lead computing green cross, is for chase shots to the drones 6, at deflection angles 30 degrees and smaller. Practicing 45-90 degree lead shooting will mislead your judgment when you reach the MA. Since combat takes place at a broad spectrum of speeds tending towards above 250mph. Another misleading tendency from the offline drones is, as your speed of chase in the MA increases above 250mph, more G force is in play between 15-30 degrees and your rounds will not hit where you expect them to from your offline practice.

Go to the TA and find Morfiend. Ask him to let you chase him around at speeds above 250mph. Then using zoom, watch how your rounds fall farther behind his plane in the same deflection angles at 275-350mph that you were destroying the drones offline at 225-250mph. And notice how much harder it becomes to hold enough lead without other factors interfering with your line of travel.

In gunnery speed increases G as you turn. G above 1G standard effects your bullets by causing them to drop shorter than they would at 1G standard requiring more lead and or elevation.

Shooting to 1000ft(333yds) while pulling G, on average, your rounds 50cal and 20mm will drop to the following:

1G - 1.5ft
2G - 6.5ft
3G - 13ft
4G - 20ft

I wish HiTech would give us some control over the speed of our offline drones to help with our gunnery training.

WW2 style air to air gunnery is the defining definition of a moving target on all levels. Then throw in a bad Internet connection night, and no wonder players come to these forums and go away unfulfilled. Every single gunnery moment in the game is an unrelated crap shoot to previous shots even if they look exactly the same.

On nights the ATT router in San Jose is not lagging or dropping packets, I hit just about anything I point the pipper at inside of 600. Even simple lagging, and my night is a crap shoot. Dropped packets............. :bhead

My roundtrip in pingplotter is 68. I should be knocking everything out of the sky I point at with a 2 digit connection.
