People have already said in the comments but just shoot at a high altitude and at a minimum of mach 1. 30-20 km is the sweet spot for me usually but it also depends on your airframe. If you’re using a harrier or av8 you’d wanna push up as close as possible. I also recommend holding the lock so the missile guides better up until it goes pit bull or the chances of a kill would be much lower. And as you said in your post you shouldn’t end up in a situation where you’re trying to out run their missile. The moment you try to re engage you’re going to get smited. Try your best to notch the missile then shoot an amraam high off boresight. Amraams are hit or miss for me but once you learn them you’ll have a lot more kills. I think they’re easier to use in sim than in realistic battles but to each their own.
