(d) GPS SEQ switch and annunciators (AUTO / HOLD) - When AUTO
sequencing mode is enabled, depressing this switch disables automatic GPS
waypoint sequencing and enables course entry from the pilot’s HSI course
needle. The amber HOLD legend is illuminated. If depressed again, the GPS
system re-enables automatic waypoint sequencing, captures the selected
course from the HSI course needle, and illuminates the green AUTO legend.
NOTE: If the To / From indicator on the CDI / HSI
indicates "From" when the GPS SEQ switch is pressed to
re-select AUTO mode from HOLD mode, the GNC 300,
will automatically calculate a course to the next waypoint
from the aircrafts current position and automatically
sequence to that waypoint.
(e) GPS APPR switch and annunciators (ARM / ACTV) - The GNC300
Approach ARM Mode is automatically engaged when the pilot has selected
an approach and the aircraft is within 30 nm of the approach airport. When
the approach mode has been armed or activated, the approach mode may be
deactivated by depressing the GPS APPR switch. When the approach mode
has been armed, the white ARM annunciator will illuminate. When the
GNC300 then detects that conditions are acceptable and the aircraft is within
2 nm of the FAF, the green ACTV annunciator will illuminate and the white
ARM annunciator will simultaneously extinguish. If the pilot has deactivated
approach mode by pressing the GPS APR switch, pressing the switch a
second time will re-arm approach mode.
(f) LAMP TEST switch. When this switch is depressed, all annunciators in the
unit will illuminate until the switch is released.
4. PILOT’S DISPLAY
The GNC300 System data will appear on the HSI when it has been selected
using the NAV / GPS switch described in paragraph 3(a) above.
