c. Fly the procedure turn. After the procedure turn outbound, set the inbound course on
the HSI.
d. On the inbound intercept to the final course, fly to center the CDI.
e. Set the GPS SEQ switch to the AUTO position. The GPS 155 will resume automatic
waypoint sequencing for the remaining approach waypoints.
6. Once the aircraft is within 2 nm of the FAF (and the approach has been armed), the ‘ACTV’
annunciator will illuminate and the CDI scale will ramp down to 0.3 nm.
NOTE: If the ACTV annunciator does not illuminate, do not descend after crossing the FAF
and fly all published missed approach procedures.
7. Upon reaching the FAF, the GPS 155 will automatically sequence to the MAP waypoint.
To fly a missed approach procedure:
If an approach is terminated, the GPS 155 may be used to navigate to the missed approach
holding point using one of the following procedures.
NOTE: To comply with TSO specifications, the GPS 155 will not automatically sequence
to the missed approach holding point. The first waypoint of the missed approach will be
displayed as the next
D
waypoint. After crossing the MAP, the pilot may activate the
waypoint when authorized. You must fly all published missed approach procedures before
selecting the missed approach holding point on the GPS.
If the approach procedure permits navigation direct from the MAP to the missed
approach holding point:
1. Release the GPS SEQ switch from the ARM position to return the CDI scale to the 1 nm
sensitivity. After the MAP has been crossed, press the
D
key. The GPS 155 will auto-
matically display the first waypoint of the missed approach as the next approach waypoint.
2. Press
E
to confirm the destination. The GPS 155 will provide a direct navigation course
to the waypoint.
