NO VNAV

[mcculchris 0]

hi i have had this for a few day and i cant seem to get it to work, i start the flight up and let it do its thing. i program the route in with sids and stars, then i put the fuel in but when i come to enter the crz FL as 180 for EGCC to EGLL, i get a message streight after entering it saying 'UNABLE CRZ ALT'. So i click clear but then my VNAV wont engage, so i take off and retract the flaps but once i have taken off i get the red overspeed bars all over the speed indicator till i touch down and they disappear, but when i am airborn and try to engage the VNAV it says 'unable next altitude', and switches to FL CH. both FD's are on all my altitudes are set in the fmc and my mcp is set to FL100ANY HELP PLEASE REALLY WANNA FLY THIS BIRD!!!!

Ok hope i can set you in the right direction, Since egcc to egll is only a short flight fl180 is a high cruize alt for this short trip, Hence the unable crz alt message. So if you were to lower the alt say to fl100 then you should be good to go with the unable crz alt will go away. Once you done this vnav should engage normally hope this helps.

FL180 is a very reasonable altitude which is easy to reach... BA use FL190 in RW for EGCC to EGLL. Get your facts right before criticizing.

And i wasnt criticing the op was just trying to solve his problem, unlike your coment helped the op in what way may i ask?. the reason he got the unable alt message is probably due to the short distance in between the weighpoints to climb to the fl180 is all i was stating

hi cheers again, but unfrtunatly that has not helped except for this time when i entered 110, a message came up saying something like unable crz alt changed to 15000any clues????

You may prefer "self teaching", but there is a lot of good information in that tutorial. It is a lot more difficult to sort through the Boeing docs..If doing the tutorial flight itself is not to your liking then just read through and apply the steps in that to your route.G

the only thing i want to gert sorted is this then i will read the manual, just want to fly!!
