Systems Integration - Honeywell KFC 150 Pilot's Manual

SYSTEMS INTEGRATION
The individual systems diagrams on
pages 7,8, and 9, show the components
and their relationships in typical KFC 150,
U P 150 and KAP 100 Flight Control
Systems. The actual components used on
individual aircraft may vary slightly in order
to optimize certification and installation
requirements.
Each system has a number of inputs
and outputs: sensor outputs are shown in
red; computation inputs shown in blue; dis-
play outputs shown in orange; and aircraft
control shown in green. The systems dia-
grams reflect that the KAP 150 and KFC
150 systems control both pitch and roll axes
of the aircraft. The KAP 100, being a sin-
gle-axis system, controls only the roll axis of
the aircraft. All sensor information (pitch
and roll reference, heading and course
datum, RNAV/VOR/LOC/GS deviation and
flags, marker receiver and static pressure
[altitude] is fed into the system's flight com-
puter).
The flight computer computes pitch
and roll steering commands (or in the case
of the KAP 100, roll commands only). In the
KFC 150 system these commands are rout-
ed through the KI 256 Flight Command
Indicator (FCI), where they are displayed on
the V-Bar as visual guidance commands.
In all three systems these steering
commands are fed
to
the autopilot compu-
tation circuits contained in the appropriate
flight computer which generates the com-
mands for the individual servos to manipu-
late the ailerons, elevator and elevator trim.
An optional yaw channel is available for
some aircraft, but is independent of pitch
and roll commands.
mands in the KFC 150 system for flight
director and autopilot provides totally con-
sistent flight director steering command and
autopilot control. There is no disagreement
in computation. The autopilot simply con-
verts the pitch and roll steering commands
from the flight computer, displayed on the
V-Bar in the FCI, into the required elevator
and aileron position commands. Full inte-
gration of flight director and autopilot allows
the pilot to delegate the manual effort of fly-
ing the aircraft to the autopilot while moni-
toring its activity with the flight director.
