I copied a real-world BA flight plan for EGLL-KBOS, but a few of the waypoints there don't exist in FSNavigator (e.g 'VIXUN'), so I had to change it a little, substituting nearby waypoints.
The plan contains both named waypoints and VORs, and also standard 'co-ordinate' waypoints like N5140, and so on. This is it, in fact:
waypoint.0=EGLL, A, N51* 28.65', W0* 27.56', +000078.74,
waypoint.1=WOD, N, N51* 27.17', W0* 52.73', +000000.00,
waypoint.2=CPT, V, N51* 29.50', W1* 13.18', +000000.00,
waypoint.3=DIKAS, I, N51* 46.62', W3* 15.55', +000000.00,
waypoint.4=STU, V, N51* 59.68', W5* 2.42', +000000.00,
waypoint.5=CRK, V, N51* 50.44', W8* 29.66', +000000.00,
waypoint.6=ADARA, I, N51* 30.00', W15* 0.00', +000000.00,
waypoint.7=5120N, I, N51* 0.00', W20* 0.00', +000000.00,
waypoint.8=5130N, I, N51* 0.00', W30* 0.00', +000000.00,
waypoint.9=5140N, I, N51* 0.00', W40* 0.00', +000000.00,
waypoint.10=4950N, I, N49* 0.00', W50* 0.00', +000000.00,
waypoint.11=LIBEK, I, N48* 5.91', W54* 6.37', +000000.00,
waypoint.12=YQY, V, N46* 9.20', W60* 3.35', +000000.00,
waypoint.13=YHZ, V, N44* 55.38', W63* 24.12', +000000.00,
waypoint.14=TUSKY, I, N43* 33.90', W67* 0.00', +000000.00,
waypoint.15=SCUPP, I, N42* 36.18', W70* 13.82', +000000.00,
waypoint.16=KBOS, A, N42* 21.91', W71* 0.42', +000016.40,
