A.V.G. Tactics
by Erik Shilling
Tactics:
First and foremost the Flying Tigers only attacked IF they had the advantage. (Altitude or speed.)
We used to listen to Tokyo Rose quite frequently. On several of her broadcast, she called the Flying Tigers cowards because we refused to stay and fight, then challenged us to stop running away. We thought this was quite humorous, and at the same time, knew our tactics were hurting them.
Also on some of Tokyo Rose's broadcasts, the number of AVG aircraft that the Japanese claimed to have shot down, was the exact number Japanese aircraft that we had destroyed. (We only lost 4 pilots in aerial combat.) This was the figure I used in giving our kill ratios. It had no bearing on the number of aircraft we or they destroy. Even Ford has said that we killed approximately 400 air crew.
Here area couple examples of the AVG attacking enemy fighters:
Attacking from head on:
If you attack head on, which the enemy was reluctant to do because our guns outranged the fighters, they would normally pull up. (If he started turning away, he would already be at a disadvantage.) You started firing at Max range, and then dive away, under these conditions we didn't turn and tangle with a Jap fighters.
Attacking the enemy from a 3 to 6 o'clock position:
Why roll rate was important: One must remember that all maneuvers, except for a loop, started with a roll. The slower the roll rate the longer it took before the turn began.
1. If he turned away, he set you up on his six; a most undesirable position for him, because he would be a dead duck.
2. The enemy invariably turned toward you, which was both normal and anticipated. With his slower roll rate, you could beat him into the turn, get a deflection shot at him, and when you slowed down to where he started gaining on you in the circle, you rolled and dove away before you were in his sights. If you haven't tried it don't knock it.
This is where roll rate really came into the picture. As far as Japanese fighters were concerned, their inferior roll rate was at all speeds. Above 240, it would take the Zero 3 second before he attained bank angle for max turn. (And the airplane doesn't start turning until bank angle is established.)
Since you could see him starting to bank you could easily bank more quickly and establish max bank angle within 1 second, and pull whatever "Gs" necessary to establish lead.
At this speed, and with your lead already established, you could maintain lead for some time before speed bled off to where the Zero could turn inside, you got the hell out. (Don't forget same speed and same "G" equal same radius of turn. Above 220 IAS the radius of the circle was determined by pilots ability to withstand "Gs." You could turn with the Zero as long as the speed was above 220 IAS.
If his reaction was only to pull at these speed the "G" factor still applies. The Zero could not take 6 "Gs," and the P-40 could pull over 9 "Gs" and most fighter pilots could "momentarily" withstand 9 "G's" or more without blacking out.
If the situation was reversed and the Zero was attacking you your roll rate would save your bellybutton by allowing you to roll to max turning bank, using 6 "Gs" or more, then continue rolling to inverted and dive. Rolling 180 degrees to dive would take less than 2 seconds, the Zero took 6. The Zero would never get a shot. He couldn't get lead, and by the time he was inverted you would already be out of range, gaining speed much more rapidly than the Zero.
It can be seen from the above illustrations that in the beginning roll rate was the primary factor in starting any maneuver except the loop. After bank angle was established then speed was the primary factor. To escape from a zero, roll rate again became the primary factor and then speed.
Anyone who disagrees with the above has never been in combat, and as far as I know, few books if any, bring this out.
