2.14 CDI Scale

By default, the scale is set to "Auto." At this setting, the CDI scale is set to 2.0 nm
during the en route phase of flight.
Within 31 NM (terminal area) of your destination airport, the CDI scale linearly ramps
down to 1.0 NM over a distance of 1 NM.
Likewise, when leaving your departure airport the CDI scale is set to 1.0 NM and
gradually ramps up to 2 NM beyond 30 NM (from the departure airport). During GPS
approach operations the CDI scale gradually transitions down to an angular CDI
scale.
At 2.0 NM before the final approach fix (FAF), CDI scaling is tightened from 1.0 NM
to the angular full scale deflection (typically the angular full-scale deflection is 2.0°,
but will be as defined for the approach)
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. For example, if 1.0 NM is selected, the
unit uses this for en route and terminal phases and ramps down further during an
approach.

Set the scale for the course deviation indicator.
Scale values represent full scale deflection for the
CDI to either side.
