    Descent and V/S-FLCH issues

    Hi guys,

    I have seen this as well. Not that often though. I do get a PM sounds warning
    " Top of descent in 50 miles " up to 100 miles out from the actual CDU
    TOD.

    As far as the Descend now function goes I find retarding the Throttels first
    and then selecting Descend now works.

    James,

    I'll try that suggestion and see if it solves the problem.

    Thanks.

    James,

    I tried your suggestion but it didn't work. This definitely worked in the
    past so I'm hoping Enrico can help. Most won't get this problem. It's only
    because I use Radar Contact I need to start down earlier than ToD.

    Cheers.

    Sorry about that.

    I use it online a fair bit if a flight ahead of me reports some chop at a
    certain flight level near a waypoint on my route.

    Hope you get sorted.

    Ray and James,

    I didn't have any problem with the descent now function. I use it very
    often
    about 10-20 miles earlier then than the calculated ToD for passengers
    confort like many airways use it in real life. The same logic is also works
    with the AltIntervention to a lower altitude and the a/c starts a descent
    with -1000F/M

    Do you have problems like these I posted? (on ToD the a/c continues in
    straight level flight without descent?, or any problems with V/S or FLCH?)


    Thanks


    Eddie

    Eddie,

    I don't use VS or FLCH. If I'm told to start down by Radar Contact I usually

    request a Pilot Discretion which if granted allows me to start down at the
    ToD. If it isn't granted I just nag until they relent .

    Enrico's back now so perhaps he can look into this.

    Cheers.

    I have been going through this as well, and I can't reproduce it... wonder
    whether it has anything to do with the way the offsets are being used/ set
    and re-set?

    If I remember correctly you have an FSBUS implementation? To avoid any
    confusion, I am not using the CPFlight hardware but clicking on the graphics

    on my end, you will understand I can't have a hardware setup for any
    possible permutation used out there.

    Can you give me a scenario where the things you observed can be reproduced
    here by me?

    Ciao

    Enrico

    Hi Ray,

    I still can't reproduce the problem here, i.e. I do get the descend now as
    it should be... looks like I am stuck trying to observe things so I am able

    to do something about them.

    Ciao

    Enrico

    Re: Descent and V/S-FLCH issues

    Hi Enrico,

    I'm using the Aerosoft MCP. I dial in the lower altitude (but don't press
    the white altitude knob) and then press Descend Now but the aircraft refuses

    to descend. Are you using the Aerosoft MCP? I wonder if that might be a
    factor?

    Cheers,

    Hi Ray,

    I remember that Enrico told me that he DID NOT have an Aerosoft MCP ( that
    may have changed since that time. )

    I, too, have an Aerosoft MCP for my 737 but rarley use the VNAV, so I cannot

    see the issue that you are describing.

    Cheers,

    Bill
