Description

The GAU-8 in the A-10 should not continue to fire after the trigger is no longer depressed. The way it functions now is like a burst mode on an m4..it will fire until a certain number of rounds have been expended, the way it should function is like a belt fed machine gun, if the trigger is pulled bullets fly down range..if it is let up the gun stops firing immediately.

You can't make you own burst length with the GAU8 Avenger.

The cannon is limited with selectable burst of one or two seconds.

This to avoid overheating, and for ammunition conservation.

the issue isn't that it doesn't fire long enough..the issue is it fires too long..even on lo settings the amount of rounds expended is far and beyond what you should need to fire. So you can leave the hard limiter in for keeping it under 2 seconds, but when CAS missions with the gun often you must keep guns on target far longer than necessary to avoid strafing areas you don't want to hit.

So is there a way to limit the total time but still cease cannon fire if the trigger is lifted before that limit has been reached?

this would be more accurate as the GAU-8 may limit the maximum time it can be fired for..but it does not limit the minimum. I am also asking some A-10 pilots and crewchiefs if the was a hard limiter on the GAU-8 to limit the cannon to a 2 second maximum or if it was just in best practice to do. Though I see no reason to remove the 2 second max as 2 second burst you better be blowing up a line of t90 tanks in a very tight column formation lol

IRL The pilot doesn't have the possibility to make burst shorter than one second.

to avoid collateral hits just avoid strafing movements. Stay straight on target until the burst ends.

that is the point of contention..in DCS A-10C(which no offense to BIS models the A-10 far more accurately) the GAU-8 fires only while the trigger is depressed. Also I asked in an A-10 forum where there are prior A-10 pilots and crew chiefs and they also agree with me

The only Hog pilot who answers says that they have, beside the burst mode, also a sniper mode for firing a single round per trigger pull.
He doesn't say anything about the other problem (and the rest of the people who answer are only ground crews as far as I understand that).

Im pretty sure he was being pretty sarcastic, I'll ask for clarification of his statement as sarcasm.

I'm also pretty sure that he was being sarcastic. Anyways, still nobody has answered your question.
(too bad one of my ex tenenats is not here anymore, he was a A10 pilot)

If this is true, wouldn't it be reasonable to assume that they (The DCS devs) have the right of it? I wouldn't think that in a simulator where they go to painstakingly difficult efforts to ensure that everything is absolutely realistic as possible that they'd leave the main cannon, one of the most important features of the A-10, in an unrealistic state.

It also makes pretty good sense that their implemented method would be the way it is. It's a logical safety measure to ensure that there is as little FF as possible on the battlefield. And I'm too lazy to look them up atm, but aren't there videos on youtube showing the A-10 firing extremely short bursts that don't fit in a 1 second or 2 second window?

CharlesDarwin, it think you got it right, the bursts lengths are manually controlled :

"In practice, the cannon is limited to one and two-second bursts to avoid overheating and conserve ammunition; barrel life is also a factor, since the USAF has specified a minimum life of at least 20,000 rounds for each set of barrels. There is no technical limitation on the duration the gun may be continuously fired, and a pilot could potentially expend the entire ammunition load in a single burst with no damage or ill effects to the weapons system itself. However, this constant rate of fire would shorten the barrel life considerably and require added barrel inspections and result in shorter intervals between replacement."

shame I didn't noticed it in my previous reply

shorter bursts are also feasible and tend to confirm it :

Those forums I posted have had some new posts and one rather rude but none the less descriptive pilot pointed out that the current system is indeed incorrect

Updated by cyrilator over 3 years ago

a full auto capability should be added in addition to the current burst limiter.

A triple selector LO/HI/AUTO is the easiest way to solve it.

full auto would resolve the strafing problems you mentioned, since the gun would only shot when trigger is pressed, not less not more.

LO/HI would also become quite useless ingame since there is no barrel life duration or overheating effect took into account.

I see no reason to keep lo/hi just two more things to cycle through when selecting weapons and they don't exist in the real A-10

there is another clip of two less than 1 second bursts

  • Target version changed from TBD to 1.14

Updated by BillyCones about 3 years ago

"In the original design, the pilot could switch between two rates of fire: 2,100 or 4,200 rounds per minute;[48] this was changed to a fixed rate of 3,900 rounds per minute.[49] The cannon takes about half a second to come up to speed, so 50 rounds are fired during the first second, 65 or 70 rounds per second thereafter."

If you put back full-auto for GAU-8, please adapt the GAU-8 ACE_SM sound for automatic fire.

The vanila sound version sounds like very wrong.

Rocko what kind of contribution needs to be made?

Time, Love and Motivation :)

Updated by CharlesDarwin almost 3 years ago

Rocko: i meant like, scripting? sounds? etc :) The gun is correct in the vanilla version just sounds like crap so I would assume that is the biggest thing?

Updated by rocko almost 3 years ago

Well someone would need to make a sound that when the GAU fires sounds the same or equally good (hearable from ground) like the current...

I think Jarhead can help with sounds, try him ;)!
