NOTE
PROCEDURE TURNS AND MISSED
APPROA",HES
Due to the sophistication of the G1000 Flight
Management System (FMS), IFR enroute and
instrument approach procedures using the G1000
FMS/GPS and KAP 140 Autopilot should be
mastered in VFR conditions (with a safety pilot)
before attempting IFR operations. Refer to the
G1000 Cockpit Reference Guide for additional
information.
Special consideration must be given to SUSP softkey operation and
KAP 140 mode selection during holding pattern, course reversal
maneuver (procedure turn) or missed approach procedures when
using the G1000 FMS/GPS. The G1000 FMS/GPS provides initial
entry cues for the procedure turn and the holding pattern but does
not provide course guidance for either maneuver.
Holding pattern operations, whether in the enroute or the terminal
environment, require temporary suspension of flight plan execution
on reaching the holding waypoint. If the holding pattern is part of
an Instrument Approach Procedure (lAP) without an associated
Procedure Turn, suspend (SUSP) mode will be invoked
automatically by the G1000 FMS/GPS on reaching the holding
waypoint (usually an IAF). Holding at an enroute waypoint will
require the pilot to manually suspend flight plan execution using the
OBS softkey and set the course pointer to the inbound course.
CAUTION
IF THE KAP 140 AUTOPILOT IS ENGAGED IN
EITHER NAV OR APR MODE WHEN THE G1000
FMS/GPS GOES TO SUSP MODE OR IF THE
PILOT MANUALLY SELECTS OBS MODE, THE
KAP 140 AUTOPILOT WILL BE OPERATING
WITHOUT A VALID NAVIGATION SOURCE.
SELECT HOG MODE FOR KAP 140 AUTOPILOT
OPERATION AND CONTROL AIRCRAFT HEADING
USING THE HOG CONTROL ON THE PFO (TO SET
THE HSI HEADING BUG).
