FLIGHT INSTRUMENTS
If a lower CDI scale setting is selected (1.0 or 0.3 nm), the higher scale settings are not selected during any
phase of flight and the selected setting is displayed instead of the flight phase annunciation. For example, if
1.0 nm is selected, the G1000 uses this for enroute and terminal phases and ramps down to 0.3 nm during
an approach. Receiver Autonomous Integrity Monitoring (RAIM) protection limits follow the selected CDI
scale and corresponding flight phases.
Changing the selected GPS CDI setting:
1) Use the FMS Knob to select the AUX - System Setup Page on the MFD.
2) Press the FMS Knob to activate the cursor.
3) Turn the large FMS Knob to highlight 'Selected' in the 'GPS CDI' box.
4) Turn the small FMS Knob to highlight the desired setting and press the ENT Key.
5) To cancel the selection, press the FMS Knob or the CLR Key.
AUTOMATIC NAVIGATION SOURCE SWITCHING
On the AUX - System Setup Page, 'ILS CDI Capture' may be changed to 'Manual'. In 'Auto' (default)
setting, the system automatically switches from GPS to LOC navigation source and changes the CDI scaling
accordingly when:
• A localizer or ILS approach has been loaded into the active flight plan
• The final approach fix (FAF) is the active leg, the FAF is less than 15 nm away, and the aircraft is moving
toward the FAF
• A valid localizer frequency has been tuned
• The GPS CDI deviation is less than 1.2 times full-scale deflection
GPS steering guidance is still provided after the HSI automatically switches to LOC until LOC capture, up
to the Final Approach Fix (FAF) for an ILS approach, or until GPS information becomes invalid. Activating
Vector-to-Final (see the GPS Navigation Section) also causes the HSI to switch to LOC navigation source,
although the change is not considered automatic to the system and GPS steering guidance is not provided
after this switch.
