... Acoording to Mike Rays "Unofficial Boeing 757/767 Simulator and Checkride Manual" it is common to "build" an DME ARC using waypoints every 20-40 degees (depending on distance to the VOR): ...

I spoke to a friend of mine about DME Arcs the other day and he told me that they were actually "never" flown in real life, and when they flew them in the simulator the procedure was always in the flight plan database in the FMC. They never actually programmed arcs using PBD waypoints. He doesnt fly the 757/767 tho, he flies the 747 for KLM
