PROCEDURES
Flying the ILS Approach
NOTE: When you LOAD an ILS approach, the ILS
frequency is automatically placed in the selected
NAV field of the NAV Frequency window.
Precision approaches can be performed with the
G1000s built in VLOC (VOR/localizer/glideslope) receiv
-
ers. The GPS receiver can be used for guidance prior to
reaching the final approach fix (FAF). Prior to reaching
the FAF ensure that the CDI has switched. The G1000
automatically switches the external CDI output from GPS
to the appropriate NAV receiver as you intercept the final
approach course. When the ILS approach is activated, the
G1000 automatically switches within 1.2 nautical miles
left or right of the final approach course. This switch will
take place within 15.0 nautical miles outside of the FAF.
NOTE: If an attempt is made to intercept the
approach course inside the FAF, the CDI must be
manually switched from GPS to VLOC (NAV1 or
NAV2) by pressing the CDI softkey.
The CDI selection can also be changed manually by
pressing the CDI softkey. Once the switch from GPS to
VLOC has occurred, either automatically or manually, it
does not automatically switch again until the approach is
reactivated or another approach is selected. To prevent
automatic ILS CDI selection, choose the ‘Manual’ ILS CDI
Capture, in the AUX – System Setup Page (the factory de-
fault setting is ‘Auto’, which enables the automatic switch
to VLOC).
This example is based upon on an active flight plan
from KSNA (Santa Ana, CA ) to KSAN (San Diego, CA
Lindbergh Field) with the ILS RWY 9 approach and
‘GATTO’ as the IAF, which includes an outbound leg and
a procedure turn.
1. Select KSNA as the destination.
2. Press the
PROC key and select ILS RWY 9
approach. From the transition window, select
‘GATTO’ as the IAF. Load the procedure. A
reminder message appears, indicating that
GPS can only be used for approach monitor-
ing. Load will maintain direct-to navigation,
while activate takes you direct to the first fix.
Activate the approach once you have been
cleared by ATC.
3. Within 30 nm of KSAN, the G1000 switches
from enroute mode to terminal mode and the
CDI scale transitions from 5.0 to 1.0 nm, full-
scale deflection.
