Hi everyoneI am new to forum and to ask for help with a problem i'm having.I have purchased and installed 'The Queen' very recently but have not been able to activate at any stage VNAV.VNAV does not arm or activate following loading of FMC or will it arm or activate in flight.LNAV is no problem.When I try to arm VNAV it lists a message 'unable cruz alt'.What am I doing wrong?Peter MurfittNew Zealand

Hello Peter,That's more of a question for PMDG rather than FS2Crew. PMDG's forum is a few up from the FS2Crew forum.However, I might check your cruise altitude field in the FMC. Perhaps it's too high?Cheers,Bryan

Many thanks BryanPeter
