AUTOMATIC FLIGHT CONTROL SYSTEM
The Automatic Flight Control System (AFCS) consists of dual IC-600s,
autopilot servos, a flight guidance controller (GC-550), a pitch and turn
controller (PC-400) and a display controller (DC-550), as follows:
− IC-600 computer - The primary component of the Automatic Flight
Control System (AFCS). Controls the symbol generator, monitors,
flight director and autopilot. Only the IC-600 #1 incorporates the
autopilot functions.
− FLIGHT GUIDANCE CONTROLLER (GC-550) - Consists of a panel
that allows control of both Flight Director systems and autopilot
functions. The GC-550 provides means for engaging the autopilot
and the yaw damper, selecting the flight director modes and the flight
director coupling. The Flight Guidance Controller also provides the
means for the remote selection of course, heading, vertical speed
target, indicated airspeed target, Mach targets and preselected
altitude.
− PITCH AND TURN CONTROLLER (PC-400) - Consists of a panel
with a Turn Control Knob and a Pitch Control Wheel. These controls
allow the pilot to manually maneuver the airplane with the autopilot
engaged.
− DISPLAY CONTROLLER PANEL (DC-550) - The DC is used to
select various features on the PFD. These include Horizontal
Situation Indicator (HSI) formats, navigation sources, weather display
and bearing pointer selection.
The Automatic Flight Control System interfaces with the following
systems:
− ATTITUDE AND HEADING REFERENCE SYSTEM (AHRS):
provides pitch, roll and acceleration information to the autopilot
system via IC-600-1.
− INERTIAL REFERENCE SYSTEM (IRS): provides pitch, roll and
acceleration information to the autopilot system via IC-600-1.
− RADIO MANAGEMENT SYSTEM: provides navigation data to the
IC-600, including short range navigation data, VOR bearings, ILS
approach data, marker beacon tone detection and transmission,
DME features and ADF.
