And Felix, what mode do you descend in then? I thought this was a discussion about VS mode and fast rules for knowing what VS to set to keep a 3deg profile, is that Vnav mode your referring to with a magenta 3 deg vertical guidance indicator on the PFD?
I am not trying to descend at 3deg. I am trying to descend efficiently and to monitor the FMC profile as a backup....amazingly it isn’t always correct. VNAV Path is great but rubbish in rubbish out, you pick up the errors early and correct them. There are also times when your given short cuts or expect them and you want to be below the path so you use other modes to achieve your self calculated path.
This may sound old school but we still have to think outside the FMC.
