inbound course within fi ve seconds. The system will fl y a
45 degree intercept heading until capturing the course. If
fl ying an ILS the GS will be captured automatically causing
the GS light to illuminate.
If using the APR mode with an HSI please tune the
appropriate ILS, LOC or VOR frequency fi rst. Use the
Course Set Knob to set the desired fi nal approach course.
Turn the heading ‘bug’ and press the HDG button if not
already in HDG mode. Press the APR but ton. The autopilot
will fl y the desired heading until course capture. The BC
and GS features operate the same way as described
above.
ALT:
To operate in altitude hold (ALT) mode fi rst fl y to and level
off at the desired altitude and then press ALT. Altitude
adjustments may be made in ALT mode by using the
vertical trim (UP/DN) switch. Moving this switch in either
direction while in ALT mode will cause the aircraft to climb
or descend at approximately 500 fpm. When the switch is
released the autopilot will maintain the new altitude.
CWS:
The control wheel steering (CWS) button located on the
control yoke allows the pilot to maneuver the air craft
in pitch and roll with out disengaging the autopilot. The
autopilot resumes control when the button is released.
FD: ( KFC 150 only)
The KFC 150 has a fl ight director ( FD) function that the
KAP 150 does not. ELITE aircraft modules using this
autopilot have a V-bar that appears on the attitude indicator
anytime the FD or AP ENG features are selected. If the FD
function only is selected the V-bar will command the user
to make control inputs to satisfy the system requirements
by maneuvering the orange delta wing into the V-bar.
