    CDU lights where is 'DSPY' ??

    Hi,

    please help in finding the read offset for the "DSPY" FMC light, the one
    above the "FAIL" light.

    Thanks

    Peter

    As far as I know, that light is not in use in the real
    aircraft (at least according to Mr. Bulfer)

    Thanks Enrico for your reply.
    Ive got the "Big Boeing FMC User Guide" from Bill Bulfer.
    According to this (Last page outfold): "DSPY indicates the active lateral or
    vertical leg or performance mode is not displayed on the current CDU
    page"

    Anyway I can live without it. But what do the FMCs route that lamp to
    generally?
    I mean, for example, the plug and play FMC from Flightdeck solutions.
    Any idea??

    Thanks

    Peter

    I do not know what you mean by "route", but if they use a
    keyboard emulator then they only have three keyboard lights
    usually... and those are used for EXEC, FAIL and MSG.

    Hi Enrico,

    with "route" I meant "mapping". Sorry that expression comes from the FSBus
    router.
    Ive seen that Flightdecksolutions HW CDU has got the 4 lights, at least the
    front panel looks alike.

    Any idea where to the DSPY light might be mapped (offset?)

    Thanks

    Peter

    None. How can it be mapped if it uses a keyboard encoder?
    Why not ask FDS?

    Hi Peter,

    The circuit board on my 737 CDU from Flightdecksolutions has
    provisions for DSPY, but only EXEC and MSG are populated with LEDs.

    Thanks,
    Ed
