Glide slope is intended to be captured from below. If so desired,
or required via NOTAM, GS mode can be toggled on/off through
presses of the “GS” button on the autopilot control panel. There
is no other required time to press the “GS” button.
In the event the pilot is attempting to capture the glide slope from
above, glide slope will be captured as the aircraft passes through
the glide slope signal, if GS mode was previously armed. If GS
hadn’t been armed, glide slope will be captured by manually
pressing the “GS” button on the autopilot control panel when
within 1 dot of glide slope centerline.
PROCEDURE TURN ILS OR LOCALIZERS
The procedure for an ILS or Localizer with a procedure turn in a
combined DFC100/FMS900w system results in the aircraft
automatically flying the outbound procedure turn heading,
automatically making the turn inbound to the inbound procedure
turn heading, then automatically capturing and flying the final
approach course.
To fly the full published procedure turn, ensure the approach is
loaded and activated in the FMS and ensure the Primary Nav
LSK is set to FMS. In this case, the DFC100 should be in NAV
and VNAV modes (other vertical modes are permitted) and the
GS should be automatically armed in blue as soon as the VHF
signal is received. Once established inbound and within glide
slope capture criteria, the previously engaged vertical mode will
automatically transition to GS. In any case, the vertical mode of
the autopilot won’t automatically change until the system
recognizes it is on final.
