Garmin GNC 300 - Manual (Page 96)

EXAMPLE 2— VOR/GPS OVERLAY
Example 2 uses the VOR/GPS RWY 19 approach into Kansas City Downtown
Airport (KMKC) from the south and illustrates an approach with a procedure turn,
which requires the pilot to set the GPS SEQ switch to the HOLD position prior to
crossing the IAF the first time. This example also illustrates the procedures required
when direct navigation to the missed approach holding point is not available.
1. Select the VOR/GPS RW19 approach and confirm that the GPS APR switch indicates an
‘ARM’ approach status. Enter the current altimeter setting of KMKC when the ‘Need pres-
press NAV’ message appears.
2. Fly towards the IAF of the approach (the JAMES intersection).
3. Two nm BEFORE crossing the IAF, set the GPS SEQ switch to the HOLD position. This
prevents the GNC 300 from automatically sequencing to the missed approach point before
the required procedure turn is completed.
4. After crossing the IAF, set the 013º outbound course on the HSI.
5. Initiate the procedure turn and set the 193º inbound course on the HSI. As you turn to the
inbound intercept heading, set the GPS SEQ switch to the AUTO position. The GPS SEQ
switch must be set to the AUTO position for the approach to go active.
6. Confirm that the GPS APR switch indicates an ‘ACTV’ approach status within 2 nm of the
FAF. Complete the approach by landing, or follow the missed approach procedure.
7. To fly the missed approach procedure, cross the MAP and press D, followed by E.
This will select the missed approach holding point as your active to waypoint.
8. Since direct navigation to the holding waypoint is not authorized, set the GPS SEQ switch
to the HOLD position to prevent automatic waypoint sequencing.
9. Set the HSI to the 080º heading and turn left to intercept the inbound course to the
holding point.
