FSUIPC throttle handling (trying to help Enrico..)


Recommended Posts

Are the fsuipc values for the throttle on page 1 under joysticks different from page 3?

I am using Project Magenta's Airbus FCU which has autothrottle lever management in it, which has been working fine on my CH Yoke and Logitech joystick where I have the FS throttle simply defined as the throttle axis of each joystick.

At the weekend I plugged in my 4 lever throttles and the lever management in the PM AB FCU stopped working and doesnt seem to recognise the throttles at all. The throttles work fine in FS.

I am assuming that the problem is related to the "Axis_throttle_set" and "Axis_throttle1_set", "Axis_throttle2_set" etc in the FS joystick setup linking to different values in FSUIPC and that the PM software is reading from a differing value.

Any help or ideas would be very welcome. I can send you a copy of the fs2002.cfg and fsuipc.ini files for the working and non-working setup if that would help.

Glenn.

Page 1 is the "all engine" throttle with no reverse section. Page 3 are the individual throttles for each of up to 4 engines. Those have reverse sections. They are different FS axis controls. Please see the FSUIPC documentation where the controls are listed in the tables.

Sorry, I've really no idea what you are talking about here. Before even attempting to use FSUIPC's joystick facilities you do need to get things working normally. Apart from the special mapping facilities in FSUIPC, the calibration is only a final "tweaking" of the values just before they get to the FS simulation engine, for more precise null and centre settings.

If PM's Airbus processing is at all realistic (i.e. fly by wire) your joystick inputs, including throttles, would actually be disconnected from FS in any case and manipulated by the flight management system, even without auto-throttle or A/P engaged. There are facilities in FSUIPC to allow this to be done -- but you will have to ask PM support what is actually going on I'm afraid.

Meanwhile, either delete the joystick section from your FSUIPC.INI file, or press the "reset" button in FSUIPC options for each axis, and get everything reasonably working without FSUIPC calibration first. Only use it to "sweeten" the results afterwards.

I think you answered my question.

"They are different FS axis controls." hence my reference to the axis_throttle_set which seems to apply to one lever for all engines and is just the "throttle axis" in the FS2002 controls.

And the reference to axis_throttle1_set and axis_throttle2_set which seem to apply to engine 1 throttle axis and engine 2 throttle axis etc when the engines have their own throttle lever.

I have all the throttles working great in FS through fsuipc, but the pm software is not picking up any throttle lever movement at all.

The throttle axis on my CH Yoke and Logitech joysticks work fine with the pm software but again its one lever for all engines.

Seeing as fsuipc really only tweaks the values I'm guessing that pm software is reading just the throttle axis as defined on page 1 of fsuipc and not from page 3 for multiple throttle axis.

Would this seem to makes sense?

It sounds plausible, but if so it seems to be rather a serious error in the design of that part of PM. What does Enrico say? He will surely know that there are folks with individual throttle controls.

Please keep me posted.
