Missile threat survival
There are two things you need to do to survive an enemy missile launch. First, avoid the missile. The second thing, which is less obvious, is do not let yourself be put on the defensive(get pinned down by multiple enemy missile launches). Avoid this by firing first or firing back at the enemy.
Avoid the missile
Here are maneuvers to avoid the missile.
This maneuver is how you can defeat close range missile shots. It is a fast maneuver to perform and it does a lot in terms of changing your position. This maneuver will zigzag you up and down and left and right quickly. To perform the maneuver, first pull back on the stick. While continuing to pull back on the stick move the stick left or right. This will apply pitch(climb/descend the aircraft along the lift vector) and roll it at the same time.
Don't get put on the defensive(pinned down)
You need to do more then just avoid the enemy's missile. You also need to put him on the defensive-that is fire a missile at him. You need to put every enemy in front of you on the defensive by firing a missile at him or turnaround 180 degrees and leave the fight. To do this, monitor your air to air radar and make sure no aircraft gets much closer than 20 miles.
A good such 180 degree turn away maneuver is to do a split s, in which you roll upside down and then pull back on the stick. Keep pulling back on the stick until you are doing a 60 degree dive. Then let go of the stick and keep going at a 60 degree dive. Build up speed until you are going 550-600 miles per hour. Then pull back on the stick and climb until you are at about 0 degrees level.
