Flying a DME Arc Approach
The GPS overlay for a DME arc approach uses
additional Jeppesen-provided waypoints to define the
arc. These waypoints are indicated by “D” as the first
letter in the waypoint name. This is followed by three
numbers which indicate the radial the waypoint lies
on. The last letter indicates the radius of the arc.

NOTE: As this manual was being written, the let-
ter/number DME arc names were being replaced
with standard five-letter intersection names. You
may encounter either naming convention for an
approach you select.
When you are cleared for a DME arc approach, you
may do one of the following to intercept the arc:
• Follow a specified radial inbound to intercept the
IAF.
• Fly directly to the IAF at the beginning of the
arc.
• Follow ATC vectors which allow you to intercept
the arc at any point along the arc.

son (Kansas) Municipal (KHUT) to Billard Municipal
