CESSNA SECTION 4
MODEL 172S NAV III NORMAL PROCEDURES
KAP 140 AUTOPILOT
U.S.
HOLDING, PROCEDURE TURNS AND MISSED
APPROACHES
NOTE
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 (if installed) should be mastered in VFR conditions
(with a safety pilot) before attempting IFR operations. Refer
to the G1000 Cockpit Reference Guide (CRG) for additional
information.
Special consideration must be given to suspend (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 (IAP) without an associated Procedure
Turn, SUSP mode will be invoked automatically by the G1000 FMS/
GPS on reaching the holding waypoint, usually an Initial Approach Fix
(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 HDG MODE FOR KAP 140
AUTOPILOT OPERATION AND CONTROL AIRPLANE
HEADING USING THE HDG CONTROL ON THE PFD (TO
SET THE HSI HEADING BUG).
