I know this has been up numerous times, but for some reason I can't get it to work 100%. When trying to land using the autopilot (totally automatic landing with both NAV radios set) the autopilot almost every time overshoot. The alignement with the runway always works perfect, but the plane stays on the same altitude and don't descend. I'm using the correct speed setting, flaps setting and get messages saying "localizer alive" and "localizer captured".
And then another question when I'm at it. I tried the FMC tutorial in the DF 737 documentation for the FMC. You prep the FMC with FL15, but you don't let it go to more than 6000 feet during the first stage according to the tutorial. But after passing a certain point, the tutorial says that you should change the altitude to FL15 to let FMC climb to the preset FL of 15. But where should I do this? The tutorial said I should set that in FMC, but I presumed that was an error in the tutorial and that they meant that I should set it in the autopilot (don't remember the correct name :-) ). Anyways, I changed the alt from 6000 feet to 15000 in the autopilot and according to the tutorial, that should make FMC climb to FL15, but nothing happened and the AC kept flying at 6000 feet.
