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. For
example:
"D258G" indicates a DME
waypoint ("D") on the 258°
radial at 7 DME ("G", the
seventh letter of the alphabet).
When you are cleared for a DME arc approach, you may do either of the follow-
ing 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 Forbes Field (KFOE) in Topeka, Kansas. The VOR/DME runway 21 approach will
be selected, along with "D258G" as the IAF.
