On a long arc technique is to fly 'thrupenny bit' shape, you can't do it in a continuous arc.
Pick a heading that will take you a little into the arc, (perhaps .2 to .4 miles on a 10 mile arc) fly out through the circumference by the same amount, turn to cut inside the arc and back out again. Repeat as necessary.
Cumbersome procedure.
Zakinthos ASTUS 2F is quite interesting with very long Arcs as you fly the 313 radial inbound towards KFN VOR to join the 25DME arc then intercept ZAK 266 radial inbound to then join the ZAK 12 DME arc to intercept the final approach.
How do you fly it in a boeing, well it's easy as the FMC tells the autpilot what to do whilst you try to go down and slow down after been left in a mess by Andravida approach. All very entertaining and much more fun than been vectored to the ILS back in the UK.
