The Comparison Computers are stripped versions of the Longitudinal and Lateral Amplifiers and contain only the minimum number of modules essential for effective monitoring and therefore occupy only one short ATR case each.
Each Comparison computer derives and compares the parameters for the longitudinal and lateral amplifier and computer channels. All longitudinal aerodynamic parameters, throttle control, pitch autostabilization, height, i.a.s., Mach number and glide-slope functions are in the longitudinal channel and the lateral channel accounts for yaw damper, azimuth, aileron and rudder, aileron damper and the dynamic vertical sensor functions.
Errors revealed by differences in signals between main and monitor units are passed to the error disconnect system which then disengages the autopilot by releasing a lock integrated with the powered control unit.
From the computer, amplified commands are passed to the torque motor actuator mounted directly on the powered control unit at the appropriate control surface.
