P3D v4 Using Event AILERON_TRIM_SET ….

[rcbarend]

Looking at some old threads like
https://www.fsdeveloper.com/forum/threads/aileron-trim.435319/#post-724173
the event AILERON_TRIM_SET was introduced in FSX (although not documented in the SDK), and has an event value range of +100 to -100 to obtain max. AileronTrim deflection (instead of the usual -16384 to +16384 for control axis SET events).

I confirm this is true, from how I use it in FSX.

My questions: (since I don;t have P3D):
- Does this still work the same in P3Dv4.3 ??
- Is this event now documented in the P3Dv4 SDK ?? (and with what description).

By the way: the same (event value range -100 to +100) applies to event RUDDER_TRIM_SET in FSX.

Thanks, Rob

Rob, that AILERON_TRIM_SET event is not documented in the P3D v4.x SDK either, so it's a toss-up if it will actually work the same as it does in FSX.

The only AILERON_TRIM and RUDDER_TRIM events listed are the _LEFT and _RIGHT event for both aileron and rudder trim control. None of those events cite the units, but presumably they are given as a percentage.

Ok, thanks for the info.
So these events remain quite obscure ....LoL

If anyone reading this, and uses Maryadi's MV22B Rel. 2 addon in P3Dv4.3: can you confirm that the nacelles operate Okay ?
Because if so, these events still work the same as in FSX.

Works in FSX; haven't tried in P3Dv4 yet but I will need to very soon. C-code follows: the return is fed through a radian to degree converter function because I pefer to see degrees.

//**************************************************************************
// Ailerons
//**************************************************************************
double getLeftAileron()
{
    double data=0;
    execute_calculator_code("(A:AILERON LEFT DEFLECTION,Radians)",&data,NULL,NULL);
    return RAD_TO_DEG(data);
}
double getRightAileron()
{
    double data=0;
    execute_calculator_code("(A:AILERON RIGHT DEFLECTION,Radians)",&data,NULL,NULL);
    return RAD_TO_DEG(data);
}
double getAileronTrim()
{
    double data=0;
    execute_calculator_code("(A:AILERON TRIM,Radians)",&data,NULL,NULL);
    return RAD_TO_DEG(data);
}

I have confirmation that events RUDDER_TRIM_SET and AILERON_TRIM_SET works exactly the same in P3Dv4.3 as in FSX.

Wrong bit of code... sorry guys

I have confirmation that events RUDDER_TRIM_SET and AILERON_TRIM_SET works exactly the same in P3Dv4.3 as in FSX.

Thanks for the confirmation, Rob. I'll let the folks at L-M's P3D team that they are missing in the SDK Event tokens listing.

However, both Events are listed in P3Dv4.3's gauges.h file for C gauge usage.

#define KEY_AILERON_TRIM_SET                (KEY_ID_MIN + 1195)
#define KEY_RUDDER_TRIM_SET                 (KEY_ID_MIN + 1196)

I just posted this info for L-M to see.
