Teroc, Congratulations on getting your PPL! I remember your very first posting on this forum....
DME arcs, most people hate them, but there are still a few airfields that have them in their procedures.
The best way to fly a dme arc? Buy an Airbus, select the relevant dme arc in the procedure at the airport, then sit back and watch in awe as the aircraft flys a beautiful dme arc with no variation on the distance at any time. Damn!
