4. As you approach the intermediate fix (CF25), a waypoint alert (“NEXT DTK 265°”) appears. Make any necessary
course adjustments.
5. Within 2.0 nautical miles of the FAF (THERO), the GPS 500 switches from terminal mode to approach mode
(“APR” appears in the lower left corner of the screen—replacing “TERM”). CDI scaling is tightened from 1.0 to
0.3 nautical mile, full scale deflection.
0.3 nautical mile, full scale deflection.
6. As you approach the FAF, “NEXT DTK 265°” appears in the lower right corner of the screen.
7. As you cross the FAF, the destination sequences to the MAP (MA25). With the CDI needle centered, fly toward the
MAP, observing the altitude minimums dictated by the approach plate.
8. As you approach the MAP, a waypoint alert (“APPROACHING WPT”) appears in the lower right corner of the
screen.
9. As you cross the MAP, “SUSP” appears above the OBS key, indicating that automatic sequencing of approach
waypoints is suspended at the MAP. If a missed approach is required, use the OBS key to initiate the missed
approach sequence, as outlined below.
approach sequence, as outlined below.
TYPE 2: Course from fix to altitude
Course from fix to altitude legs shows the specific target altitude on the Active Flight Plan and
Default NAV pages. The missed approach sequence for the Palmdale VOR/DME RWY 25 approach
includes a course from fix to altitude leg. In this instance, the leg corresponds to the initial phase of the
missed approach, which reads “Climb to 5000’ outbound via PMD VOR R-282”.
includes a course from fix to altitude leg. In this instance, the leg corresponds to the initial phase of the
missed approach, which reads “Climb to 5000’ outbound via PMD VOR R-282”.
1. After crossing the MAP, press the OBS key. The missed approach sequence is automatically offered, starting with
the ‘course from fix to altitude’ leg. The “NEXT DTK 282°” waypoint alert appears in the lower right corner of the
screen. Follow the missed approach procedures, as published on your approach plate, for proper climb and heading
instructions.

2. Note that within a few seconds of pressing OBS to release suspend mode and start the missed approach
sequence, “SUSP” re-appears above the OBS key as the GPS 500 returns to suspend mode. This is normal when
flying a ‘course from fix to altitude’ leg and indicates that automatic leg sequencing is suspended.
