GPS CDI
The CDI section of the System Setup Page allows you
to define the range for the on-screen course deviation
indicator. The range values represent full range deflection
for the CDI to either side. The default setting is 'AUTO'.
At this setting, the CDI range is set to 5.0 nautical miles
during the "en-route" phase of flight. Within 30 nm of
your destination airport, the CDI range gradually ramps
down to 1.0 nm (terminal area). Likewise, leaving your
departure airport the CDI range is set to 1.0 nm and
gradually ramps UP to 5 nm beyond 30 nm (from the
departure airport). During approach operations the CDI
range gradually ramps down even further, to 0.3 nm.
This transition normally occurs within 2.0 nm of the final
approach fix (FAF).
If a lower CDI range setting is selected (i.e., 1.0 or 0.3
nm), the higher range settings are not selected during
ANY phase of flight. For example, if 1.0 nm is selected,
the G1000 uses this for en-route and terminal phases
and ramp down to 0.3 nm during an approach. Note that
the Receiver Autonomous Integrity Monitoring (RAIM)
protection limits listed below follow the selected CDI
range, and corresponding flight phases.
The CDI Section of the System Setup page displays the
following data:
• Selected CDI range (auto, 5 nm, 1 nm, 0.3 nm)
• The current system CDI range (5 nm, 1 nm, 0.3
nm)
• The ILS CDI capture mode setting (auto, manual)
The CDI Section of the System Setup page allows the
following operations:
• Setting the selected CDI range (auto, 5 nm, 1 nm,
0.3 nm)
• Setting the ILS CDI capture mode (auto, manual)
