    Airbus Real A32x MCDU EKCH-LKPR planning and calculation.

    Hi,


    I have a couple of questions as to how the MCDU calculates the following situation:
    A flight into LKPR from the north with an ILS24 approach.
    The flight is from eg. EKCH and via GOLOP1S STAR.


    The STAR has no vertical constraints and ends with a manual heading of 062 - vectors for the ILS.


    Questions regarding this arrival:
    1- How does the MCDU calculate Top of Descent?
    2- How does the MCDU calculate Remaining distance (and thereby fuel at Arrival)?


    Thank you for enlightning me

    Hi

    Manual legs are computed as if the ACFT flew from the initial point if that leg directly to the next "normal" waypoint.

    Thanks Jean Luc,

    The "Flight plan discontinuity" AFTER the manual leg. Should that remain or be deleted for the manual leg to be flown?

    it cannot be deleted, it is part of the manual leg.

    Ok - understood.
    The whole background for my query is that both fuel at destination, time-to-go were be off, and no TOD was calculated by B35 inbound to Prague.
    Distance-to-go seemed to be ok.

    That's all still part of VNAV, which as you know is still work in progress (for a long time...).

    Ok - just as long as it is related. Usually there is a ToD, just off
