After flying the first leg, landing and then taking off for a second leg, upon reaching the point of T/D, it does not show on the ND. While on the ground prior to my second leg, I deleted the previous route and reloaded the FMC properly and had all the waypoints with spd/altitude restrictions for the STAR I was going in on setup correctly but it does not show the T/D for some reason? Also after flying the first leg, on subsequent legs the VNAV keeps disconnecting with the FMC saying, "unachievable descent path" or something similar. It is saying this on a published STAR that I have flown many times? All the FMC alt/spd entries are correct with what the STAR says but the FMC just keeps disconnecting on me, very wierd behavior. On the first leg and on initial FMC loading, everything works fine.

Did you ensure you reset the FMC completely for the second leg?George

Do you have altitude constraints on any of your STAR waypoints? If you do, try to delete the constraints and see if that helps.:-beerchug TGIF

Yes, I went to the RTE page and hit DELETE and then selected LSK1.
