    Hi Ray,

    I am not sure where the panel fits in with this... in any case, please do
    download the current new build I uploaded two days ago to
    www.projectmagenta.com/updates.html

    Re: Descent and V/S-FLCH issues

    Hi Enrico,
    Just for information here.
    I see that people are using the Aerosoft MCP B747 for a B737.
    Please note that in B744 operations a descend or a climb always has to be
    confirmed by pushing the ALT sellector after dialed in a new altitude.
    Nothing may happen before.

    Same for a speed intervien.

    Just for info so that B737 and B747 aren't mixed up

    Ciao

    Re: Descent and V/S-FLCH issues

    Hi Enrico,

    Just tried the latest CDU update and it works now but not the way Michel
    explained for a B747. After selecting a lower altitude on the MCP, the aircraft
    initiate a decend just after hitting the 'Descend now' on the CDU without
    pushing the ALT knob on the MCP.

    I do not know if this is true only for a B737 operation but it is already an
    improvement.

    Thanks,
    Serge.

    I think it is correct for a 737. Once within a certain range (50 miles?) of
    the computed TOD I think any reduction of Alt on the MCP should give rise to
    the DESCEND NOW option, and, in any case, if the option is offered it
    should most certainly work when selected (no matter which aircraft model, I
    should think).

    The altitude override button on the MCP (which is an airline option in any
    case on the 737) actually changes the altitude requirement for the next
    waypoint so forcing a recomputation of TOD and, usually as a result, an earlier
    descent -- though of course it could be a climb and a later TOD!

    If that button is not provided the same thing is accomplished through
    altitude entries in the FMC legs page.

    I expect those here more expert in 737 matters will correct me if I'm wrong
    on these points, but that is the way I understand it.

    Regards,

    Pete

    Hi Enrico,

    I only mentioned it in case it was a factor. I know you have many skills but

    mind reading probably isn't amongst them

    New versions being downloaded now and I will try a flight this evening.

    Thanks.

    Re: Descent and V/S-FLCH issues

    On 737 after Descent Now is pressed the EXEC button lits. The descent
    starts
    AFTER pressing the EXEC button.. (Now Descent now initiates the descent
    which is wrong for 737NG)

    Themis

    I'm happy that a solution for the T/D problem has found! I have changed
    10-15 private mails with Enrico for this strange problem. (It was posted
    public earlier but none had noticed at that time)

    Makes sense, yes. I just said "if the option is offered it
    should most certainly work when selected", and you confirm this, with
    selection being pressing the DESCEND NOW LSK and then the EXEC.

    As I said, I didn't think it needed the (optional) alt intervention button
    pressing on the MCP as well -- I always thought that was basically a
    short-cut method of changing the actual altitude constraints in the FMC's plan.
    Thus its optional nature. Evidently it is different on a 747 though.

    Pete

    RE: Descent and V/S-FLCH issues

    Btw


    I was lucky to be in a 734-400 cockpit from LGAV to LCLK and the captain
    explained to me that there is also another way to make the Descent now
    option, exept this we discribed and Themis posted just before.

    They are dialing a lower altitude in MCP and they just push the Alt
    intervention, the result is the same, the a/c starts a descent with -1000
    feet/min while is in VNAV mode and descending to capture path.
    They just save to move the hand from MCP to CDU and press the DES page,
    then
    Descent Now option, then EXEC.
