SYSTEM OVERVIEW
GPS CDI
The GPS CDI Box on the System Setup Page allows the pilot to define the scale for the Course Deviation
Indicator (CDI) when GPS is the selected navigation source and also displays the current system value for the
CDI scale. The range values represent full scale deflection for the CDI to either side. The default setting is
'Auto' (refer to the CDI description in the Flight Instruments Section for information on CDI scaling).
If a lower CDI scale setting is selected (i.e., 1.0 or 0.3 nm), the higher scale settings are not selected during
any phase of flight. Note that the Receiver Autonomous Integrity Monitoring (RAIM) protection limits follow
the selected CDI scale and corresponding flight phase.
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 (2 nm, 1 nm, 0.3 nm, Auto) and press the ENT Key.
COM CONFIGURATION
The COM Configuration Box on the System Setup Page allows the pilot to select 8.33 kHz or 25.0 kHz
COM frequency channel spacing.
Changing COM channel spacing:
1) Use the FMS Knob to select the System Setup Page.
2) Press the FMS Knob momentarily to activate the flashing cursor.
3) Turn the large FMS Knob to highlight the channel spacing field in the COM Configuration Box.
4) Turn the small FMS Knob to select the desired spacing and press the ENT Key.
