VNAV 737NGX

Nothing to do with Candy.Used the MD11 to fly the STAR mentioned by Ryan into KLAX. SEAVU2 -ILS25L.For the purpose of VNAV, selected the RNAV (Z) approach to 25L.-Observations:The next waypoint on the STAR and following approach, is sequenced as soon as the nose of the aircraft symbol hits the magenta waypoint position.However: the next altitude restriction is sequenced some time later, when the aircraft center, which is the (MD11) present position, is passing that waypoint.As these two instances are not simultanious, this triggers a temporary level-off, de-stabilising the continuous descent profile.(for this reason I use FPA for the final stages of the approach.)As far as I can observe, the profile is calculated very excactly and synchronising the Waypoint sequencing with the next profile altitude at the same instance, would give a more smooth descent.May not be the problem that is investigated for the upcoming 737NGX. For the MD11 it would make it more like real life.Hope it is of help.Regards,Harry
