Auto-Slewing

The G500H system is designed to interface with GPS navigator units and also
manage up to four different CDI course pointers (GPS1, NAV1, GPS2, NAV2)
independently. The G500H will automatically slew the NAV course pointer
to the correct final approach course when a ILS, LOC, LOC BC, LDA or SDF
approach is active in the GPS navigator and the appropriate frequency is in
the active window in the navigator. The G500H will Auto-Slew the HSI course
pointer for an ILS, LOC, LOC BC, LDA, or SDF approach when the steps below
are completed in the following order:
1) The desired approach is selected and activated in the navigator (this can be
verified by the approach waypoints appearing on the GDU620 MFD Nav Map
Page or FPL Page).
2) The appropriate frequency is the active frequency in the navigator.
3) The CDI selection on the GDU 620 is changed to NAV course pointer for the
active navigator.
NOTE: If the NAV course pointer is displayed for the active navigator
when the approach is activated and the localizer frequency is tuned, the
pilot will need to switch to another CDI source and then back to NAV
for the course pointer to Auto-Slew.
For example, if NAV1 is currently selected, the pilot must:
press the CDI soft key twice: NAV1>GPS1>NAV1
OR
press the 1-2 soft key twice: NAV1>NAV2>NAV1
NOTE: For LOC BC approaches, the course pointer will slew 180 degrees
from the inbound course.
