It used to be 140 ATE for Classic and 50 for NG.
That's basically what I'm asking for. I haven't seen the AFM of the plane concerned, but I was told that the min. A/P disengagement height is somewhere around 140', yet 1CH CAT II approaches are approved. Trying to figure out how it is supposed to work.
Can any of the 737-400 Jocks check their AFM and tell me the minimum disengagement height?
