DME Arc Approach
STEP 4: If you've loaded the approach, but not
activated it, press PROC and select "Activate
Approach?".
STEP 6: As you fly the DME arc, "Set Course to
###°" alerts you to periodically adjust the course
select on the external CDI (or HSI).

3. Within 30 nautical miles of KTOP, the GPS 500 switches
from en-route mode to terminal mode and the CDI scale
transitions from 5.0 to 1.0 nautical miles, full scale
deflection.
4. If you have not already activated the approach (in
step 2), ensure to do so when cleared for the approach.
See page 55, step 5 for a description of this operation.
5. As you approach the IAF (LEBVY), a waypoint alert
("NEXT DTK 351°") appears in the lower right corner of
the screen. As the distance (DIS) to the IAF approaches
zero, the alert is replaced by a turn advisory ("TURN TO
351°").
6. Follow the arc, keeping the CDI needle centered. When
using an autopilot, the course select on the CDI (or HSI)
must be periodically updated with the desired track
(DTK) to ensure proper tracking through the arc.
Whenever the course select setting and desired track differ by more than 10°, a "Set course to ###°" message
appears on the Message page.
7. The next point in the approach is an intermediate fix, labeled "D025G". As you approach this intermediate fix, a
waypoint alert ("NEXT DTK 205°") appears in the lower right corner of the screen. As the distance to this fix
approaches zero, the alert is replaced by a turn advisory ("TURN TO 205°"). Dial this course into the CDI (or HSI)
using the OBS knob and initiate a standard rate turn to this course heading.
8. At 2.0 nautical miles from the FAF (TOP VOR), the GPS 500 switches from terminal mode to approach mode. CDI
scaling is tightened from 1.0 to 0.3 nautical mile, full scale deflection.
9. As you approach the FAF, a waypoint alert in the lower right corner ("NEXT DTK 214°") appears. Select this
course on the CDI (or HSI) using the OBS knob and turn to the final course segment (FAF to MAP) heading.
