NAV III
The distance from the waypoint to start the turn will vary with
groundspeed, degrees
of heading change, etc., but will usually be
approximately 0.5 nautical mile from the waypoint. Flight plan
sequencing to the next waypoint will occur at approximately the
midpoint of the turn.
Roll Steering works only if all the following conditions are true:
1. GPS must be the navigation source shown on the G1000
HSI.
2. The GPS navigation computer must be executing an active
flight plan.
3. The KAP 140 must be engaged in NAV or APR mode.
4. The GPS must not be operating in OSS mode (PFD).
NOTE
When on an active GPS flightplan with the KAP 140
Autopilot coupled in NAV or APR mode, waypoint
course changes greater than approximately
140
0
could result in a turn rate that reaches the autopilot
bank angle limit. The pilot may need
to change the
KAP 140 to HDG mode (also arm NAV or APR
mode) and manually set the intercept heading to
help the autopilot lock on the new course.
HOLDING PATTERNS AND PROCEDURE TURNS:
When operating IFR on an active GPS flight plan, enroute or
transitioning to the terminal environment, a holding pattern or
course reversal maneuver may be necessary. The
G1000 GPS
does not provide course guidance through these maneuvers. The
pilot must set both the
G1000 and the KAP 140 to the correct
operating mode and provide course guidance.
The Holding
Pattern is usually shown on the MFD Navigation Map
(for a published holding fix), but it is not included as a leg of the
flight plan.
GPS flight plan execution must be paused by entering
OSS mode and using autopilot HDG or NAV modes, as applicable,
to perform the maneuver.
