COUPLED ILS APPROACH WITH PROCEDURE TURN
NOTE:
Configuration of a GNS 430 or GNS 530 is required for a coupled ILS
approach.
The external navigator (GNS 430/530), G3X, and autopilot can be used to fly a
full ILS approach with procedure turn, from the enroute environment to the missed
approach point.
Setting up a coupled ILS approach:
1)
EXTERNAL NAVIGATOR: Ensure the ‘GPS’ indication is showing in the
lower-left corner
. If not, use the CDI Key.
2)
G3X: Ensure that GPS1 is the selected navigation source on the PFD or
PFD Page (use the
CDI SRC
Softkey to cycle through external navigation
sources if necessary).
3)
EXTERNAL NAVIGATOR: Select and activate the ILS approach using the
PROC Key.
4)
G3X: From the PFD or PFD Page, press the
HDG/ROLL
Softkey to access
the autopilot lateral modes and then press the
AP NAV
Softkey to activate
GPS Mode. The autopilot should start navigating to the IAF (Initial
Approach Fix).
Or:
Press the
NAV
Key on the GMC 305
5)
EXTERNAL NAVIGATOR: Tune and identify the localizer frequency by
pressing the VLOC Flip-flop Key. (Note: The external navigator should have
automatically loaded the localizer frequency into the standby VLOC slot.)
6)
G3X: From the PFD or PFD Page, press the
ALT/PTCH
Softkey to access the
autopilot pitch modes and then press the
AP APPR
Softkey to arm LOC and
GS modes. Press the
AP ALT
Softkey.
Or:
Press the
APR
Key on the GMC 305
GPS Mode is now active and LOC Mode is armed in the roll axis. ALT
Mode is active and GS is armed in the pitch axis. The autopilot should now
navigate the entire approach from the IAF (Initial Approach Fix) to the MAP
(Missed Approach Point) with the only adjustment being the throttle.
NOTE:
Check step #5 if the external navigator doesn’t automatically switch
from GPS to VLOC Mode shortly after turning inbound on the final approach
course.
