Flying a DME Arc Approach
The GPS overlay for a DME arc
approach uses additional Jeppesen-
provided waypoints to defi ne the arc.
These waypoints are indicated by “D”
as the fi rst letter in the waypoint name.
This is followed by three numbers
which indicate the radial the
waypoint lies on. The last letter indi-
cates the radius of the arc.
When you are cleared for a DME arc approach, you may do either of the following to
intercept the arc:
• Follow a specified radial inbound to intercept the IAF.
• Follow ATC vectors which allow you to intercept the arc at any point along
the arc.
This example is based upon a flight from Hutchinson (Kansas) Municipal (KHUT) to
Billard Municipal (KTOP) in Topeka, Kansas. The VOR/DME runway 22 approach will
be selected, along with “D258G” as the IAF.
1. Select Billard Muni (KTOP) as your destination, via the D key or as the last waypoint in a
flight plan.

were being replaced with standard five-letter intersection names. You
may encounter either naming convention for an approach you select.
