I loved the DME arc from the north into Kingston. In our dinasaur B727 we started our turn 2.5 early to join the 15 DME arc at 250 knots and used the simple 1% lead to join and stay easily within .3 miles of arc. A gentle bank made it like a U control model airplane flying the arc. I used the rmi to simulate the control lines. It was so easy but fun.
