FLIGHT INSTRUMENTS
GPS CDI SCALING
When GPS is the selected navigation source, the flight plan legs are sequenced automatically and
annunciations appear on the HSI for the flight phase. Flight phase annunciations are normally shown in
magenta, but when cautionary conditions exist the color changes to yellow. If the current leg in the flight plan
is a heading leg, ‘HDG LEG’ is annunciated in magenta beneath the aircraft symbol.
The current GPS CDI scale setting is displayed as ‘System CDI’ on the AUX - System Setup Page and the full-
scale deflection setting may also be changed (2.0 nm, 1.0 nm, 0.3 nm, or Auto) from this page. If the selected
scaling is smaller than the automatic setting for enroute and terminal phases, the CDI is scaled accordingly
and the selected setting is displayed rather than the flight phase annunciation.
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.

When set to ‘Auto’ (default), the GPS CDI scale automatically adjusts to the desired limits based upon the
current phase of flight (Figure 2-35, Table 2-2).
