Complete certain in-game tasks to get each achievement.

When fighting enemy fighters, never give them a chance to fire at you. Go into full speed. Once you have a lock, fire off a missile, and switch targets to see if any other fighters are in range. If not, get out of dodge and go down to about 500ft. Slow down to about 45% and stall until you have the advantage of getting behind another aircraft. Then do the same thing again.
