Just so you know this is total bull. The gun will slow the plane when fired but in NO WAY will it cause the plane to stall and fall out of the sky. There were some initial problems with the engines stalling due to sucking in the exhause gasses from the gun firing but those were worked out fairly quickly. The biggest issues/reasons why they rarely fire long bursts are 1) there are few tanks that require a sustained burst(gun is super accurate and deadly) 2) the barrels overheat quickly 3) the gun only carries 1350 rounds maximum and fires 60-70 rounds a SECOND. So the gun can fully expend its entire payload of ammo in about 20 seconds (fires at a fixed rate of 3900 rounds a minute).
Quoted from Wikipedia in case you dont believe me. "
The A-10 engines were initially susceptible to flameout when subjected to gases generated in the firing of the gun. When the GAU-8 is being fired, the smoke from the gun can make the engines stop, and this did occur during initial flight testing.[2] Gun exhaust is essentially oxygen-free, and is certainly capable of causing flame-outs of gas turbines. The A-10 engines now have a self-sustaining combustion section. When the gun is fired the igniters come on to reduce the possibility of a flame-out.[14]
The recoil force of the GAU-8/A[15] is 10,000 pounds-force (45 kN),[3] which is slightly more than the output of one of the A-10's two TF34 engines (9,065 lbf / 40.3 kN each).[16] While this recoil force is significant, in practice cannon fire only slows the aircraft a few miles per hour.[14]"
