PROCEDURES
Flying the ILS Approach
NOTE: When an ILS approach is loaded, the ILS
frequency is automatically placed in the NAV
Frequency window. Please, see VHF NAV/COM
Pilot's Guide for details.
Precision approaches can be performed with the built
in Nav (VOR/localizer/glideslope) receivers. The GPS
receiver can be used for guidance prior to reaching the
final approach fix (FAF). Prior to reaching the FAF the CDI
should be set to NAV1 or NAV2. The G1000 automatically
switches the external CDI output from GPS to NAV1 or
NAV2 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 prior the FAF.
NOTE: If an attempt is made to intercept the
approach course beyond the FAF, the CDI must be
manually switched from GPS to NAV1 or NAV2
by pressing the CDI softkey.

pressing the CDI softkey. Once the switch from GPS to
Nav 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, select the 'Manual' ILS CDI
Capture, in the AUX – System Setup Page (the factory
default setting is 'Auto', which enables the automatic
switch to Nav).

2. Press the PROC key and select ILS RWY 9
approach. From the transition window, select
'GATTO' as the IAF. Choose 'LOAD?' or 'ACTI-
VATE?'. A reminder message is displayed, indi-
cating that GPS can only be used for approach
monitoring. '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 range transitions from 5.0 to 1.0 nm, full-
range deflection.
4. If you haven't already activated the approach,
be sure to do so when cleared for the
approach.
