    Re: ISRS Alignment

    Hallo!

    I want to post a first alpha release of IRS for 747-400 pmsystem. I use this
    at the moment with hardware connection.
    Please feel free to discuss this here and I wait for your response.

    Re: ISRS Alignment

    Hi Peter,
    Thank you very much. I will check as soon as I can ( still waiting addional

    phidgets)
    In the real one it takes 10 minutes, so I suppose by increasing the "600"
    value we can obtain that.
    I suppose the messages (I mention in my reply) are in the hands of Enrico,
    as will the CDU coordinates ?

    YawDamper only can work if IRS is aligned and if there is hydrolic power.
    Will have to check which hyd cicuit is responsible

    Re: ISRS Alignment

    Good morning!
    10 min full alignmenttime please donít change 600, only change the counter
    increment from 2 to 1 (on 3 positions), so it will take double time to reach
    600. (I took 600 as counter target, because this means 600 sec=10mins to
    me)

    Messages in upper EICAS are in hands of Enrico, I asked him to put this on
    the list. (but not only msg for IRS, I asked him to design a possibility to
    send every msg (inkl. priority) from pmsystem to GC EICAS, so we can make
    the rest.)

    CDU: it is possible to enter IRS position at the moment, the only thing is,
    that IRS Position could be entered before IRU Selectors have been set to
    nav. But I think it must be in this way for people which donít work with
    pmsystem. Its only a (very) small issue.

    Peter

    Hi Peter,

    Thank you very much for all the info.
    As soon my additional phidget cards are in, I can connect the IRU's. Badly
    at this moment the 0/16/16 are out of stock and no delivery date is fixed.

    Yep very good idea, because they are "hunderds" of system messages.

    Yep I know and indeed normally the line of green rectagles are coming up
    only after the switches are set to NAV. I think these things still have to

    be adapted in order to work together (CDU/PMSystem).

    Many thanks

    Easier said than done, but I am working on it.
