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 num-
bers which indicate the radial the way-
point lies on. The last letter indicates
the radius of the arc.
As this manual was being written, the letter/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 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.
