BASIC kinematic avoidance, no tactical considerations:
You need to imagine Me with a 2 meters stick aiming your chest going towards you at walk speed.
How do you avoid me touching you with the stick?....
You change direction (notch/pump/abort) at a distance > of the length of the stick and at a speed equal or greater than me.
This stick length, or distance, is called MAR (minimum abort range) if you stay above your are safe, if you go below you will need hard maneuvering to avoid and survive.
As the 104's buds said, With time you will start to understand how the geometry works, you will try different distances and different speed until it work, there is no secret...you need to practice.
FYI : DCS AIM120C MAR @ block [2] for mach 0.9/0.9 fighter is : 14Nm rounded up ish
So: @ 14Nm of bandit, if you go afterburner, even buster do a Level 180° turn at mach 0.9 or more you will defeat any aim 120c coming from that mach 0.9 block [2] bandit shooting at you Long/medium...
Now Mar is variable for each block of altitude, speed of bandit, your speed, your payload(manouvrability ex: 3 tanks), Your way to go cold, (pump/abort buster/gate?) if you are already in the crank, and most off all the missile against you.
