You can find many posts like yours if you search this forum for "unable crz".Read this:UNABLE CRZ ALT means that predicted Top-OF-Descent for the flightplan, weight and cruise altitude entered is calculated to be before the Top of Climb. The vertical flight path predictor is very very accurate in this plane. Therefore :(a) Check your flightplan -- for good measure DELete dicontinuities(:( Check your flightplan altitude constraints -- some terminal procedures are completely wrong. If necessary delete one or two silly constraints.© Check your weight -- in particular check units from PMDG menu(d) Try another one.Michael J.http://www.precisionmanuals.com/images/for...argo_hauler.gifhttp://sales.hifisim.com/pub-download/asv6-banner-beta.jpg
