Hi there;

I keep getting an event that arms the spoilers in mid flight (PMDG aircrafts 747 & 777).  The event showing in the FSUIPC log is below:

1428313 *** EVENT: Cntrl= 86637 (0x0001526d), Param= -11819 (0xffffd1d5)  <86637>

I checked PMDG Commands and there is nothing assigned to any of the three Spolier commands. Any advice on how to identify the control or the source of this event.

 

Thanks in advance.

Is there anything in your P3D button/keyboard or FSUIPC assignments for spoilers?  It may not be coming from PMDG but the sim or FSUIPC if there is an assignment there as well.  

Hi Paul;

Thanks for the response, no nothing is mapped aside from the Ctrl-/ and I haven't been pressing it while flying.  I also tried changing this assignment from Shift-/ but still the same behavior persisted!

Can I track Ctrl 86637 somehow?

Best,

Mustafa

It sounds like a "phantom" control assignment sending spurious inputs.

You should go through every controller listed in P3D's control menu and make sure there are no unintended axis and/or button assignments--this includes everything connected to the PC, including game controllers.

If you know how to decode the assignments in the FSUIPC.ini (and also any aircraft-specific FSUIPC profile for the airplane) you should also look for anything assigned to a spoiler control or offset.  If not, removing the ini and allowing FSUIPC to rebuild a new configuration might be the way to go.

Thanks Bob;

So I may have found the culprit here. As when I went through your suggestions, I started looking at the FSUIPC axis controls one by one, and the axis I have assigned to spoilers is a B737 mod from Flight Simulator Controls Modifications. It is always in the stowed position during flight obviously, so I didn't think of it, but it turns out that the input coming out of it to FSUIPC during calibration is wild, jumping 1000s of points without it being touched sometimes crossing beyond the armed values of the calibration.

I'm going to tinker with a bit, update the driver and calibrate it in Windows, and will report back.

Thanks,

Mustafa

Yup, that would do it. 

Sounds like a dirty/noisy pot in the controller.  You can try rapidly moving the lever through its range 10-20 times--sometimes that'll force the pot wiper to clear spurious debris off the resistive surface.  More often than not, though, it means a new pot is needed.

He could also buy some electrical contact cleaner and see if that helps. Not particularly expensive.

That only works if you can get into the pots without destroying them.  From looking at the pix on the website the OP provided, those pots are pretty hard to get to, and are rotary pots that are usually sealed.  If i had to tear things down far enough to get the bad pot out, I'd really just rather replace it (maybe all of them) with new.

Thanks for the feedback all. I tried moving the control 20 times and some compressed, and that did the trick... so far 🙂

Thanks again,

Mustafa
