Approach Procedures
LOCALIZER APPROACH
To fly the complete published approach, select the approach and
IAF desired, load and then activate the approach at the
appropriate time in the GPS Nav-Com navigator, ensure the
correct navigator is selected in the PFD Primary Nav LSK, and
ensure the DFC90 is in NAV mode.
When flying a Vectors-To-Final approach, use the Heading knob
and the “HDG” button on the autopilot control panel when ATC is
issuing vectors.
NAV APPR can be armed prior to capturing the localizer beam
but it is highly recommended to wait until ATC clears you for the
approach before trying to arm NAV and APPR. To arm NAV
APPR while still i
n Heading mode, press the “HDG” and “NAV” (or
“HDG” and “APPR”) buttons at the same time. Once armed, the
system will automatically capture the localizer signal and
transition out of Heading/Vectors mode on its own.
