Looking for "Below GS" and "Spoilers armed" annunciator light offset

[PeterH]

Hi,

anyone out there who knows the offsets for (B737) "Below GS" , "Stab out of trim" and "Spoilers armed" lights?

Any hint highly appreciated.

Thanks and best rgds

This is one of the special offsets within fsuipc reserved for PM. I do not know for sure whether you would need the PM software to use it. I think the PM software somehow looks via this offset into FS to see whether the plane is below GS or not. Then you could read this offset with other software too.

You could use fsinterrogate (see the dowson page on www.schiratti.com) and down the sdk package. Then fly an approach under the GS and look with fsinterrogate into 04Fe.

Post your result here please.

If this is a PM only offset, it will not work without PM. Yes FSUIPC will read the data for the offset but it has nothing to pass the offset to.

Offset 04FE does nothing without a running PFD because the Offset is a PM Offset. That means only PFD writes to this OFFset and not FS or anything else.

Not sure about lights, but as documented in the FSUIPC SDK, the spoiler arm flag in FS (with or without PM) is at 0BCC. There's no easy flag for "below G/S". The FS G/S needle position is in the 1 signed byte offset 0C49, ranging from -127 "up" to +127 "down". I think the up and down refer to the needle position, not the aircraft, so a +ve number would mean you are below the GS. But for a warning you'd want to allow a little leeway.

Hi,

meanwhile found an offset for "Below GS" under 4FE Bit 1.
There´s also "Master warning" and "Caution" Bits 2 and 3.
I´m a bit confused about that Master Warning (or is it Fire warn?) and Master caution as there are other offsets for this as well. So which ones are the ones to use for the Master warning Push button and its light and for the Master Caution push button and its light? In the sysvar there are different offsets for example the caution switch (56F3.1 and 56F8.0).

Currently I´m desperately trying to get my sixpacks working, but to no avail I can figure out a logic in its behaviour. Once I reload the PMsystem I can get e.g. the Flt Ctrl light to come up by switching off the Yaw damper on the 737 overhead. This works until I push the recall switch or the Master caution. Then APU, Elec, Eng and FLTCtrl as well as HYD, Anti Ice, Doors get illuminated and will not go off even on the overhead everything seems to be ok. Also the Master Warning is lit (56F8.0) and can´t be cancelled.

Tried besides the stock 737 Pmsystems file different other logic files as given here in this forum, but all behave the same illogical way. Can someone please explain the difference between offset 5530 /5531 and the offsets 5540 / 5541 as they both could be read by my sixpack Led HW. Which ones are the right ones for the sixpack lights and which ones are the right offsets for the master warning (red), master caution (yellow) and the recall push button (operated by pushing in the sixpack)?

What am I doing wrong here?

Any hints highly appreciated.

Thanks a lot in advance

Best rgds

Any answer to this last question?

Do the Master Warning and Master Caution lights/switches work within PM (maybe only for boeing, but not for airbus?).

What about the BelowG/S offset?

And to complete the thing, any OFFSET for turning on a LED for GPWS warnings? I think I found one, but didn't seem to work...

Thanks!

This controlled by pmSystems logic and pmMCP.

Just use the Offset, it works!

Because there is no logic that controls this Offset, it cannot work.

Thomas, can you give me any guidelines for writing logics in pmSystems? I am already familiar with several programming languages, and would like to write several things for pmSystems A320 logics, including the GPWS, the Master Warning and Master Caution.
Thanks!

I don't what more is needed than this because the pmSystems language has simple syntax like a simple Basic language, any other is your own creativity.

I don't know what I can tell more!?
