Hello,Currently I am standing at Schiphol ready for my flight to London Luton.I have put the flightplan in the FMC...filled in the ZFW etc.When I filled in the CRZ FL (FL240) I get a error message: Unable Cruise ALT.And there are no Altitudes given in the LEGS page. And even if the Fuel tanks are full at the PROG page I see at the waypoints 0.0 fuel.Can anyone help me? I have this problem since a few days now...therefore i havn't any problems with it.I use FS9 (without the update) PMDG B73NG -800/-900Kind Regards,Guy Haalebos

Guy,I don't think you get a fuel prediction before you've entered an altitude. You are probably too heavy to reach that altitude in that short a time. Try a lower altitude.Hope it helps,
