System Integration
The system diagrams show the compo-
nents of the KFC 250 Integrated Flight Control
System and their relationships.
The system is functionally divided into four
parts: Sense, control, compute and display.
All sensor information (pitch and roll reference:
slaved compass: RNAVIVORILOCIGS;
DME:
marker receiver: and air data) is fed into the
KCP 299 Flight Computer.
The Flight Computer computes pitch and
roll steering commands. These
two
com-
mands are routed to the KCI
310
or KI 256
Flight Command Indicator where they are
displayed on the V-bar as visual steering com-
mands. These steering commands are also
fed
to
the Autopilot computation circuits con-
tained in the Flight Computer where the steering
commands and aircraft yaw rate information
