I successfully completed a flight using the FMC/CDU...and now I am ready to try another.BUT - I am unable to "clear" the settings on the CDU in order to load another flightplan. It keeps giving me the following error message from the previous flight "APPROACH VREF NOT SELECTED".How do I clear the CDU?Any ideas? Claus

Claus,Go the the RTE page 1, and then hit the delete key, and the press L(ine) SK 1L, which should delete the destination dep runways, and clear all other values from the FMC.

I too am unable to clear te FMC after doing as instructed.Ken Fortin

Okay here's how (a buglet crept in)- after landing, at some point you may receive the vref message- turn off AP, recycle FD- stop the aircraftThis will put the FMC in preflight mode.anthonyAnthony MertonPrecision Manuals Developmenthttp://www.precisionmanuals.com
