I programmed a flight plan from KSFO to KLAS using the correct SID and STAR and correct waypoints
but am told by the FMC “ Unable 8000 at sunst” which is a waypoint close to Las Vegas. Cruising altitude
is 30000. I even tried reprogramming it again with a lower altitude of 15000 feet and still received the same
error message. Please tell me what I am doing wrong so I can correct this error message and program the
correct flight plan that the FMC will say is okay.
Thanks a lot,
