Calibration of two throttles for idle and reverse thrust

[joenp]

:?: On page 3 FSUIPC throttle calibration, I set the throttle1 reverse to

-16256, and full thrust to 16265. Idle set to -12300..-12150.

When trying the throttles , the max position works fine..(N1 91). When

throttle set to Idle position the engine rpm decreases ..(N1 38), but when

moved to max reverse.. the engine rpm decreases to idle(N1 24) but no

reverser action occurrs. Please help!

1. What version of FSUIPC please?

2. What does the "OUT" value show as you reduce the throttle back from the idle position to full reverse? Is the IN value actually getting to your -16256?

3. Observe the throttle quadrant on the panel. What is the throttle lever doing?

4. Check that you don't have more than one throttle axis assigned to the throttle -- this can happen if you have (or had) more than one joystick/device attachment. Look in FS Options-Controls-Assignments, see if there are other devices with axes assigned to either Throttle 1 or the generic single throttle-does-all axis.

4. Is this with all jet aircraft, or a specific add-on? I think some Airbus implementations have throttle management which interferes with any attempts at direct throttle settings. Test things on the default 737, say, first.

Using Win98, FS2002

1. Version FSUIPC is 3.411

2. cannot get an idle position on any lever position except when at

min. -16256. Tried to set idle at 0 position or any where below 0, but the idle setting button does not produce an idle rpm.

3.Lever on quadrant moves in conjunction with the throttle lever.

4.Checked all joysticks in FS Options-controls -- no other devices are

assigned to either Trottle 1 or the generic single throttle.

5.No not specific same on all default aircraft.

What's the "idle setting button"? How do you mean "0" position? Where are you reading this?

When the Input from your throttle is reading -16256 (the "IN" value in FSUIPC), what is the OUT reading? If you've calibrated correctly it will be something like -4096. That's maximum reverse thrust.

Lever on quadrant moves in conjunction with the throttle lever.

Down only to zero, not into the reverse zone?

I really cannot picture what you are seeing from here. The individual throttle facilities always work setting reverse, this has never been any sort of problem. Please show me the Joystick calibration section of your FSUIPC.INI file.

To add to my confusion I believe there is a problem with my throttles. They are three wire grounded pots. Further to ur query as to the readings

-- when the lever is moved to max up the "OUT" value is 16256 and so is

the "IN"value. When lever down fully the "OUT" value is -16256 and so is the "IN" value. That zero that i mentioned appears in the "OUT" and"IN"

boxes when throttle is in center position. Is this the problem or am I

way out in left field? Attached is the FSUIPC INI file. Thanks for your

patience and help.

Sorry , the configuration did not go thru. Here it is:

[Joystickcalibration]

FlapsSetControl=0

ReverserControl=66292

MaxThrottleFor Reverser=0

AileronTrimControl=0

RudderTrimControl=0

CowlFlaps1Control=0

CowlFlaps2Control=0

CowlFlaps3Control=0

CowlFlaps4Control=0

SlopeAileron=0

SlopeElevator=0

SlopeRudder=0

MapThrottle=Yes

Throttle1=-16256,-512,512, 16256

Hope this helps

when the lever is moved to max up the "OUT" value is 16256 and so is

the "IN"value. When lever down fully the "OUT" value is -16256 and so is the "IN" value.

If the IN and OUT values are always the same, then FSUIPC is not processing the axis at all. The button above on the left will read "Set". If FSUIPC was doing anything it would read "Reset". Please, please, please, follow the steps in the documentation to calibrate in FSUIPC.

You are Mapping a single generic throttle to the 4 separate ones! Why? I thought you said you had two throttles? If you have only one throttle axis, that should be assigned to the single generic throttle in FS, not to Throttle1. If you have two separate throttle axes you do NOT calibrate or Map the single throttle value -- that isn't even used.

The values shown above are default values. It looks like you've not been through the calibration process either?
