NORMAL PROCEDURES
(Continued)
The Procedure Turn is included as a leg in the flight plan along with
the instrument approach procedure selection. Course guidance is
supplied through the turn to outbound course lock on, but is
discontinued after approximately 1 minute. G1000 OBS mode is
not required but the KAP 140 must be set to HOG mode and the
HOG bug used to provide guidance through the course reversal.
When established inbound, change from HOG to APR mode for lock
on to the final approach course.
For a KAP 140 that has been operating in NAV mode on an active
GPS flight plan:
On arrival at the Holding Fix, set the KAP 140 in HOG mode
and provide course guidance by manually adjusting the
G1000 HOG bug to command turns and heading, as
applicable. Pause G1000 flight plan execution during the
holding pattern by using the OBS mode selection on the PFO.
Set the correct inbound holding course on the HSI course
pointer and NAV mode may be used for the KAP 140 on the
inbound leg of the holding pattern for course guidance, but
HOG mode must be used for the remainder of the holding
pattern maneuver. At the end of the holding procedure, exit
OBS mode to start the flight plan executing again and set
NAV mode on the KAP 140 to lock on to the course. See the
Garmin G1000 Cockpit Reference Guide for further
information.
Arriving at the IAF (usual starting point for the Procedure Turn
maneuver), the G1000 will command the autopilot to turn to
the outbound course and will provide course guidance for a
short time (approximately 1 minute). Unlike the Holding
Pattern, the G1000 includes the Procedure Turn as a leg in
the flight plan, so no OBS mode change is needed. Set the
HOG bug to the Procedure Turn outbound leg heading and
push the HOG button on the KAP 140 to start the tum. After
the correct time flying outbound, adjust the HOG bug to make
the turn to the procedure turn inbound heading. When
established on the procedure turn inbound, push the APR
button on the KAP 140 to lock on to the final approach
course. See the Garmin G1000 Cockpit Reference Guide for
further information.
