can't find this offset

[737nut]

Hello,

I looked thru the manual and i can't seem to find the offsets for these commands which are assignable with-in fsuipc.

AP Pitch Ref Inc Up

AP Pitch Ref Inc Dn

AP Pitch Ref Inc Select

Sorry if i missed it.

Thanks,

ROb

Why would you think there's an "offset" for every FS control event?

I've no idea what those do or if they actually do anything at all. Do they do anything? If so, what? Are they related to the AP "attitude hold" option (offset 07D8) which I've never seen work, or actually do anything? If you know about these things please do tell me.

I see in FSX, via SimConnect, I can get hold of a value called AUTOPILOT PITCH HOLD REF, so if you like I can put it on my list for adding in the next update to FSUIPC4. Seems to be in Radians, so it would probably have to be a floating point value. Not sure how INCs and DECs work on a continuous value like that -- we'd need to determine the increment, in radians.

I've taken a look to see if I have anything related to this in FS9, and it looks like I could fish this out from SIM1.DLL as well -- at least for 9.1. It looks like it may have moved since 9.0.

So, if it does actually do anything useful, please describe it to me and I'll look at adding it into both FSUIPC3 and 4 in due course.

These things only get added as folks ask for them, but in order to add them to my documents I need to understand a little about them. Okay?

Meanwhile, for all and any FS controls you can send them to FS from an FSUIPC client program via offset 3110.

Pete,

The Pitch Up and Pitch Dn work perfect with my DF727 Autopilots Pitch control knob. The select function isn't working. Apparently the elevator channel select lever on the DF727 AP needs to physically move to activate this mode. I can see the function try and work (using your FSInterrogate) when using the select command but since the lever doesn't move the command doesn't stay in place.

So,

Pitch ref up ---- works w/ Dreamfleet 727 AP

Pitch ref dn ---- Works w/DF 727 AP

Pitch Ref select --- does NOT function correctly

Not sure if this is what they were there for but this is what they do for me in FS9.1 :)

Thanks,

Rob

But that is with an add-on aircraft. The DF authors may have merely made use of those controls to drive their cockpit. That doesn't mean they actually do anything inside the FS engine themselves. The fact that it is interlinked to the "elevator channel select lever" (whatever that is! ;-) ) seems to indicate that it may be purely an add-on function in this case.

Can you find any default aircraft in which they have a function at all? If so I can try them here and see what happens inside FS. Otherwise I don't think I can really get very far.

You might get more info about this from the DF folks themselves.

Incidentally, controls called "Select" don't normally do anything much other than put keyboard focus on that item, so that the usual +/- keys operate the INC/DEC controls on the right thing.

As I said earlier, if all you want to do is operate the INC/DEC controls via an offset, you can do so via offset 3110. If you want a read-out of the actual pitch angle, however, that is another matter.

Incidentally, I didn't understand this bit:

I can see the function try and work (using your FSInterrogate)

What function and what offset? I'm missing something here, evidently.

Oh, BTW, FSInterrogate isn't "mine", but Pelle Liljendal's. ;-)
