Re: ISRS Alignment

[Peter Parnreiter]

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.

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

Good morning!
10 min full alignmenttime please don’t 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 don’t work with
pmsystem. Its only a (very) small issue.

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.
