Trouble with Flaps


Recommended Posts

I have not been flying for a while but have been updating each time a update come through. Currently on 4.325 installed.

I now notice however that I cannot get the full range of flaps on my PMDG 744X. There was no trouble previously and it looks like everything should work. I have assigned the level to send the data to FSUIPC for calibration. Looking at the out from this it gives the plane and says it has 7 detents with Incr of 5460. Moving the lever through its full range it definately outputs 7 different values. However in FSX it is only showing up as 6 and only gives me up, 1, 5, 10, 20, and 25. If I want 30 then I have to use the VC flap lever.

I have seen this once before but cant remember what the issue was. I do think it was something to do with a earlier version of FSUIPC though.

Looking at the out from this it gives the plane and says it has 7 detents with Incr of 5460. Moving the lever through its full range it definately outputs 7 different values.

And what are they?

Are you calibrating the detentes in FSUIPC, or just letting the positions take care of themselves?

However in FSX it is only showing up as 6 and only gives me up, 1, 5, 10, 20, and 25. If I want 30 then I have to use the VC flap lever.

6 increments at 5460 gives a range of 32760, which is so near the maximum of 32767 that I can't see how it could fail to reach.

I can try it here on the FSX default 747.

Okay. it works okay here with the default 747. The 7 values I get are

-16383, -11052, -5592, -132, 5328, 10788 and 16254.

Not sure why the first increment is 5331, but the rest are 5460 (well the last is 5466, but close enough). But nevertheless, they all work.

I am letting the positions handle themselves and has worked in the past okay.

I get exactly the same figures as you do

-16383 which should be UP

-11052 which should be Flaps 1

-5592 which should be Flaps 5

-132 which should be Flaps 10

5328 which should be Flaps 20

10788 which should be Flaps 25

16254 which should be Flaps 30

However the PMDG only gets to flaps 25. It has always got to flaps 30 up until about 4 weeks ago when I last few it. After the layoff it no longer gets there.

I did try a default 747 from FSX and it sees all the detents okay and gets to flaps 30. Not sure what is happening as there has been no change at all to my PMDG setup.

Is there an offset I can view to see what FSX is seeing for the flaps?

That's totally weird.

Monitor 0BDC as U16 for the flaps control, 0BE0 and 0BE4 for left and right flaps indicators, also U16. If you set this to display in the FS window and in the Normal log you can see them in real time and also the Log will contain the SimConnect reads and writes.

0BDC goes to 16384 here when FSUIPC sends its top value. I've not idea why that doesn't work for PMDG. Maybe I need to stretch the values over a bit more. The fact that my first increment is less than the computed value disturbs me a bit. I wonder if that's a new thing. I'll trace it here, see why.

Have done that. When I pull the lever down I see a jump of 2731 for a split second on 0BDC and then it goes back to zero. As I continue to pull down I get the 2731 again.

Results are:

0BDC 0BE0 0BE4

0 0 0 Shows flaps up

2731 0 0 Shows flaps 1

5461 12411 12411 Shows flaps 5

8192 13653 13653 Shows flaps 10

10924 14894 13894 Shows flaps 20

13653 15638 15638 Shows flaps 25

Thats all I get. I tried to attach the logfile as well but it said the extension log is not allowed. I tried txt as well and same result. Will try and PM it.

I suspect that's because PMDG is doing its own thing here, and"Flaps1" has no trailing edge flaps I think, just leading edge slats which are simulated in its code not in FS. It also must be intercepting the 16254 I'm sending for full flaps and deciding that isn't enough. Their code evidently hasn't much idea of a "range" of possible values for flap notches.

I can only suggest that I investigate why my increments are not as even as I would have thought, and try to fix that for you to re-test. I'll let you know.

No, no need. In any case you should always ZIP things. For pure text, which is what logs are, you can paste the relevant extracts into your message in any case. If the only logging you enabled was the monitoring I asked, and you only operated the flaps once, it should be very short in any case.

It looks like the reason for the lowest increment being less than the others was to get the rest spotted more centrally in their "zones", matching FS's values more consistently. It seems, however, that this 'correction' is lowering the top value enough to defeat PMDG's code.

Please try http://fsuipc.simflight.com/beta/FSUIPC4327.zip and let me know. I've adjusted only the top-end, so if it is the top value i use 16383 instead of whatever the relevant number of increments provide.

Tried it and I now get flaps 30 but it will not select flaps 25. Goes straight from flaps 20 to flaps 30 missing flaps 25 alotogeather.

But I've only changed the top value, nothing else. That makes no sense at all! :-(

What are the numbers you are seeing now?

I really don't know how to solve something with a shifting interpretation. Something is weird with that aircraft.

[LATER]

It just occurred to me that perhaps the interpretation of the values by the PMDG aircraft is much worse than we thought. The only feasible explanation for the change you have seen is that one of the others is actually being ignored. Something like this:

-16383 which should be UP os okay

-11052 which should be Flaps 1 is okay but which may in fact be also giving flaps UP?

-5592 which should be Flaps 5 is okay but which maybe giving 1

-132 which should be Flaps 10 but which may be giving 5

5328 which should be Flaps 20 but which may be giving 10

10788 which should be Flaps 25 but may be giving 20

16254 which should be Flaps 30 but is actually giving 25

That's only one possibility. In fact any one of them apart from the first and last may be being ignored (or rather not differentiated).

I'm sorry, but I really cannot do anything without more information. I'm going to have to ask you to run some tests. We can do this best with a little Lua program. So, save the following in the Modules folder as "TestFlaps.lua":

n = -16384
while n < 16384 do
   n = n + 256
   ipc.control(66534, n)
   flapctrl = ipc.readUW(0x0BDC)
   flapindex = ipc.readUB(0x0BFC)
   ipc.log(string.format("Param = %d gives Handle = %d and Flap Index %d", n, flapctrl, flapindex))
   ipc.sleep(250)
end

Then go to FSUIPC options, enable Lua logging in the logging page (so it gets its own Log file -- else it'll share the FSUIPC4 one), the in the Keys or Buttons page, Reload Keys or Buttons (ro get the Lua file seen), then assign a key or button to "Lua TestFlaps".

Also "Reset" the Flaps calibration in FSUIPC4's calibration page -- otherwise it will work on these controls and we won't get the real picture.

Back in FSX, use the button or key to run the test. Watch the flaps lever. I put the Sleep in there to slow things down a little -- the test should take 128 x 250 mSecs, or 32 seconds (roughly). The reason for the sleep is so you can watch it if you want, and of course to give time for the lever to move.

After, check the Modules folder for "TestFlaps.log". Show it to me. Here's the result for the default 747. The lines I then marked <<<<< are those closest to the values FSUIPC4 is computing using increments. As you can see, with the exception of the two extremes (full down and full up), these are reasonably near the centre of each range. I could afford a slight shift, probably upwards.

At this stage, I'm not even sure there will be values which work for "normal" aircraft and the PMDG 747. There may be a need for the notch calibration not only to define the places on the lever for detentes, but also the values to be associated with each.

Ugh. I do hope not. Things are complicated enough as they are.

Let's see your results.

Unfortunately I'm out all tomorrow, so it won't be till Saturday (maybe very late Friday) I'll be able to taker a look.

The reason for the sleep is so you can watch it if you want, and of course to give time for the lever to move.

I just realised that the "ipc.Sleep(250)" line needs to immediately follow the "ipc.control" line to give time for the flaps to operate before reading the flap index (the control position should be okay, as that's immediate). Maybe also the delay needs to be more. But all that it would only affect the fringes of each range. We want to aim for near the centres if at all possible.

Okay I did the test flaps and got the following output.

It looks strange because the flap lever did indeed step through all the flap settings from Up, 1, 5, 10, 20, 25, and 30. However the log looks like it only did 6 steps.

Okay I did the test flaps and got the following output.

It looks strange because the flap lever did indeed step through all the flap settings from Up, 1, 5, 10, 20, 25, and 30. However the log looks like it only did 6 steps.

This is even more puzzling. The maximum for the reported position of the Flap Lever by SimConnect was 13653, which, on the default 747, equates to Flaps 25.

Maybe you need to move that Sleep and increase it substantially. Maybe the Flaps readings I'm getting back are more delayed with the PMDG. Try and increment of 512 instead of 256 and increase the Sleep to 1000 (1 second between each) -- and move the Sleep line to just after the Control line, so it now looks like this:

n = -16384
while n &lt; 16384 do
   n = n + 512
   ipc.control(66534, n)
   ipc.sleep(1000)
   flapctrl = ipc.readUW(0x0BDC)
   flapindex = ipc.readUB(0x0BFC)
   ipc.log(string.format("Param = %d gives Handle = %d and Flap Index %d", n, flapctrl, flapindex))
end

Oh, one other idea. If you go to the Logging tab and disable the Lua logging but select the Log console display, then run FSX in Windowed mode with the console log display visible as well as the Throttle Quadrant, you will see the log entries from the Lua program at the same time as the lever moves and you can make a note of which line (by time, very left on each line) equates to which visible position.

I've really currently got no idea how to solve this. I hope we get some useful, non-conflicting, information.

Anyway, you just caught me before bed. It's nearly 3 am here. I'll be out tomorrow.

The visible changes occur exactly when the Flap Index changes each time.

The extremely strange thing about this is that it was working 100% and the only changes have been to update to the latest version each time. I may try going back a few versions to see if this fixes it.

----LATER

I went back and installed 4.318 and tested again the flaps and it went through the full range. Tried 4.322 and tried that but it would only get to flaps 25. No flaps 30. Went back to 4.318 and full range back. Tried 4.316 and again it gave the full range of flaps. I did notice that with 4.316 and 4.318 that the flaps 1 comes on between the position where the flaps 1 comes on in the later versions.

Something must have changed between 4.318 and 4.322 that has caused this issue.

Got back early so before I have to go out again I'm catching up a bit.

Tried again and got the following this time.

Aha! At least it sohws clearly how it gets to full flaps:

   213237 LUA: Param = 15872 gives Handle = 13653 and Flap Index 5
   214236 LUA: Param = 16384 gives Handle = 16383 and Flap Index 6

So even values as high as 15872 still only give Flaps 25, despite the proper spacing which should be allowed being, what was it? 5460. I would have expected and hoped for at least half of that be allowed for Flaps 30!

The visible changes occur exactly when the Flap Index changes each time.

Well, that's one good thing, anyway. At least that means the PMDG modelling hasn't destroyed the relationship between its flap positions and the SimConnect indices.

Something must have changed between 4.318 and 4.322 that has caused this issue.

Hmm. Could be a side effect of some corrections to make flaps work properly on some of the default aircraft. Maybe my adjustment by 128 -- the one now giving the uneven increments.

I can't keep changing things back and forth, fixing one and breaking another. I need to look for a solution that works for everything. I'll examine your figures more closely, see what I can come up with.

After a cursory glance through those last results, and comparing it with the values FSUIPC sends out, I see that each of my selections are right on the lowest edge of the ranges PMDG computes! Very dodgy. Maybe it worked before, but it must have been a close shave!

It appears as if, rather than selecting ranges where the central value is the one with the correct 5461 increment, they've used that increment to determine the CHANGEOVER point! Seems to deliberately be made critical! I would guess that they never even bothered to look at how FS itself interpreted the values! Very sloppy programming in my opinion -- surprising for PMDG!

I'll experiment with making my choices, instead of near central to me computed ranges, something like 75% of the way though. That should put them safely within the lower half the PMDG ranges without upsetting any other aircraft. At the same time I'll force 0 flaps to be minimum value and full flaps to be maximum - they obviously allow no leeway at all in the latter case!

This is exactly what I've done in version 4.328, now available in the FSX Downloads announcement.

I've tested it with most FSX default aircraft, and I even managed to find and install a copy of the PMDG 747X which Lefteris sent me a while back when we were testing the effects of turbulence on the LNAV function. It seems to work fine with that too now! (I forgot i had it -- I searched my archives and there it was! ).
