Approach
Flying an ILS approach:
1) Transition from GPS Navigation Mode to Heading
Select Mode.
a) Load the Runway 35L ILS approach for KCOS
into the flight plan and select ‘VECTORS’ for
the transition.
b) Use the HDG Knob to set the Selected Heading
after getting vectors from ATC.
c) Press the
HDG Key. The autopilot turns the
aircraft to the desired heading.
d) Use Heading Select Mode to comply with ATC
vectors as requested.
2) Arm LOC Approach and Glideslope modes.
a) Tune the localizer frequency.
b) Press the
APR Key when cleared for approach
to arm Approach and Glideslope modes. ‘LOC’
and ‘GS’ appear in white as armed mode
annunciations.
c) The navigation source automatically switches to
LOC. After this switch occurs, the localizer signal
can be captured and the autopilot and flight director
determine when to begin the turn to intercept the
final approach course.
3) There are two options available at this point, as
the autopilot flies the ILS approach:
• Push the AP DISC Switch at the decision
height and land the aircraft.
• Use the GA Switch to execute a missed
approach.
