Cant follow FMC-Legs speed/alt when on auto pilot

Recommended Posts

It follows the points but not the speed and Alt, Vnan and Lnav is active with autopilot CMD-A

Ok just re changed the speed/alt in the FMC for next leg, 260/7000 and executed (its current showing 240/5000 in the hud) but speed/alt stops at 240/6680...........vnav/lnav is active and autopilote CMD-AF/D and A/T is active..Looks like it slowly comes down to 240/6000 at the end off waypoint, but it should be 260/6000 still showing 240/5000 in the HUD? why dos not the new setting change in the HUD to 260/600 as set in the FMC?

There is a speed restriction below 10,000 feet of 250. The fmc uses 240 below 10,000 thats why its not going to 260 at 7000. You can edit this I believe but I cant recall where right off hand.

No it should not, if you have a 240/10000 limit. Please read the tutorial. It explains very well the concept of monotonic path. PS. You must have also seen an UNABLE XXX KTS AT YYY (waypoint name) message.
