Hi again

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,

The default 737-800

I reprogrammed the flight at 20000 feet and the error message was gone and all the waypoints had speed snd altitudes set. Strange because a flight from San Francisco to Las Vegas can easily fly at or above 30000 feet with plenty of time for the decent to make those altitudes at Las Vegas. Probably a little glitch with the FMS

Just wanted you to know
