With the release of Boyd’s Aerial Attack Study, pilots realized that the high-stakes death dance of aerial combat was solved.[20] Boyd said that a pilot going into aerial combat must know two things: the position of the enemy and the velocity of the enemy. Given the velocity of an enemy, a pilot is able to decide what the enemy is capable of doing. When a pilot knows what maneuvers the enemy can perform, he can then decide how to counter any of the other pilot’s actions. The Aerial Attack Study contained everything a fighter pilot needed to know.
