August 25, 201114 yr Couple of things to check: 1. Are you overweight?2. What happens if you try FLCH at the profile speed? Trevor

August 25, 201114 yr VNAV FMC SPD/LNAV/VNAV PTH That is not right if you are supposed to be climbing !!! It would be normal enough for cruising though. Frederic Steiner.
August 25, 201114 yr Sorry to intervene, but I have the same problem following the tutorial 1.When reaching FL100 (with 250kn), speed drops to plm 210, with the green 'up' at the speedtape.Until FL100, everthing went normal.Grz.Paul Regards, Paul - near EHRD
August 25, 201114 yr Author vnav path happened when I decide to cruize , now im in cruize and the n1 cannot maintain crz speed so i have to set manuelly the N1 to get to my crz spd... Francis Tremblay Montreal, canada
August 25, 201114 yr That's why I suggested trying FLCH. It sounds like the vertical profile is messed up. Did you setup the CDU correctly? Trevor
August 25, 201114 yr opt : FL356 max /382 i wouldnt go above OPT. Try FL350, going higher than this and climb will be slow. This means a longer time at a higher thrust setting than CRZ which costs fuel/money.
August 25, 201114 yr Author Yes im cruizing at fl350 but cannont maintain CRZ speed..., And yes i set CDU correctly Francis Tremblay Montreal, canada
