The sophisticated KFC 325 Digital Flight
Control System provides 3 axis flight director
and autopilot systems and includes servo
motors for operating the rudder, aileron, elevator and elevator trim controls. The servos are controlled by a Flight Computer that has pitch and roll information supplied by a KVG350 Vertical Gyro (or vertical gyro with similar outputs) and direction information from a KSG105 Directional Gyro (or directional
gyro with similar outputs) and/or the aircraft radio receivers.


This KFC325 interfaces with the EFIS system introduced by modification NB-M-1531.

The KMC 321 is a mode and annunciator panel. Armed and coupled modes are displayed with an orange rectangle above each button. A serial bus transmits information between the KMC 321 and the KCP220 Flight Control Computer. This reduces the amount of interconnect wires needed and ensures that the annunciated modes are the actual modes in use by the Computer.

See below for information on using the KMC 321 annunciator panel.
