Yes, I know the best way to evade missiles it not getting into situation where you're fired upon in the first place but still it has to happen sometimes.
When fired upon at long range, defeating a missile is easy by outrunning it. Turning around 180 degrees from the missile, afterburners on, and pitching down to trade altitude for speed. It gets you out of the missiles flight envelope, the missile loses it's energy and you live.
At close range if enemy plane is on my six I just break as hard as I can as if I'm trying to turn into the missile(or opposite of the missile if fired upon from 12) while dispensing chaffs and flares continuously. The bad thing is IR missiles don't give out a warning signal.
What gives me trouble is when fired upon from let's say medium range, where missile is not that far away that you can outrun it, nor so close that you can evade by breaking immediately. What I tried doing is putting it on my 3/9 line and when I can see it in the distance start dispensing countermeasures. However, this rarely works because the missile easily predicts my flight path and timely adjusts its. What did work is doing the same thing(3/9 line) but when it's really close start turning hard into it which will cause the missile to overshoot. The only problem is that I did it with external views where you can view the missile, without it it gets really hard to determine its closure. I also tried maintaining my heading when fired upon,maintaining it on 12, and then when the missile is really close breaking hard, but spotting the missile is the problem again.
There are old pilots and there are bold pilots, but there are no old bold pilots.
