CHAPTER 5: AIRCRAFT
AUTOPILOT
KAP 150 / KFC 150
The KFC 150 and KAP 150 are both two-axis automatic pilot
systems that operate almost identically. These autopilots
each provide pitch and roll stabilization and automatic trim
as well as automatic response to all selected autopilot
modes. The only difference being the KFC 150 also has a
fl ight director (FD) function. Since the KAP 150 does not
have a FD function it uses a standard attitude reference
without V-bar commands.
To use the KAP 150 and KFC 150 autopilots please follow
these simple instructions:
Before each use please press the TEST button and wait
for the system to perform its self-test function.
AP ENG:
The most basic form of autopilot operation is to engage
only the
auto-pilot engage (AP ENG) mode button. In
this mode, with no other modes selected, the aircraft will
maintain the pitch attitude existing at the time of AP ENG
engagement and will fl y with the wings level. Use of the
vertical trim (UP/DN) switch in this mode will affect an
approximate 0.9 degree per second pitch change.
HDG:
In heading (HDG) mode the aircraft will maintain the
heading selected by the heading ‘bug’. Be sure to place
the heading bug in the desired position before engaging
the HDG button, as the aircraft will immediately begin
turning in the shortest direction toward the ‘bug’.
