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) Ensure the appropriate localizer frequency is
tuned.
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.
