    Re: T/D is too early placed in path.

    Hello Themis,

    I need a couple of more details... do you have a cost index
    table in your aircraft file? Was a cost index set? What to
    and what are the parameters in that table?

    Ciao

    Enrico

    Hi Enrico,
    Cost Index was 80
    Aircraft PMDG 737-700 (PMDG 737-700 aircraft config file on CDU)

    All the parameters are in this file (I have downloaded from your site)

    Hi,

    I will check... but can you e-mail me the file? We have too
    many on the site (there will be a purge soon).

    But I also do not understand one thing... you say the T/D is
    too early, but you use the Descend Now option, descending
    earlier than the calculated descent?

    Have you tried raising the angle for the 80 cost index
    entry, then the descent will start later.

    Ciao
