Describes a scheme for the mechanization of fixed-wing, lateral/directional dynamics as demonstrated on the EAI 580 analog/hybrid system. A review of the complete six degrees of freedom program is included, along with useful guidelines of aircraft simulation in the engineering laboratory. (Author/JN)

Illustrates use of analog/logic computer to produce realistic display of the actual motion of computer simulations in addition to the usual variable-versus-time solution. An arbitrary vector-generating circuit is postulated and utilized in several examples, the most general of which shows vector length, angle, and position all changing with time.…
