CDI SCALING
The CDI has the same angular limits as a mechanical CDI when coupled to a VOR or LOC. When coupled
to GPS, the full scale limits for the CDI are defined by a GPS-derived distance (5.0, 1.0, or 0.3 nm). The
current GPS CDI scale setting is displayed as 'System CDI' on the AUX - System Setup Page, and the scale
setting may also be changed (5.0 nm, 1.0 nm, 0.3 nm, or Auto) from this page (Figure 2-22). When set to
'Auto' (default), the CDI scale automatically adjusts to the desired limits based upon the current phase of
flight:
• Leaving the departure airport the CDI scale is set to 1.0 nm and gradually ramps up to 5.0 nm beyond 30
nm from the departure airport
• The CDI scale is set to 5.0 nm during the enroute phase of flight
• Within 30 nm of the destination airport, the CDI scale gradually ramps down to 1.0 nm (terminal area)
• During approach operations, the CDI scale ramps down even further to 0.3 nm. This transition normally
occurs within 2.0 nm of the final approach fix (FAF).
