Hi All,

I am interested in disabling the XPlane-11 physics model to test a research flight dynamics model. The procedure I want to do is as follows:

1. Disable XPlane-11 flight engine

2. Read button/switch status's and control (joystick/throttle/peddles etc) positions via UDP.

3. Feed this though research flight model

4. Update Lat,Lon,Alt, Phi,Theta,Psi & peripherals 

The various pause plug-ins seem to prohibit reading the stick positions, so too does the freeze plugin in https://www.avsim.com/forums/topic/552318-freeze-vs-pause-plugin/

Setting "sim/operation/override/override_flightcontrol" to 1 allows me to read the controls, however does not freeze the state (Lat,Lon,Alt, Phi,Theta,Psi) of the aircraft.

Would anyone have any advice on how to approach both freezing the state and allowing sampling of hardware.

Thanks in advance,

Brendan

Hi,

you want sim/operation/override/override_planepath. It is an array but it seems only the first index is important.

at a guess, the array is likely for the AI aircraft positions

all the default datarefs and commands are stored in datarefs.txt and commands.txt in the resources/plugins folder

In any array that considers AI aircraft (i.e. with a length of 20), the user aircraft always has index zero.

Hi,

I am in a similar situation as I want to disable the physics of an aircraft to add my own,

override_planepath is great but it disable the command inputs, 

I tried override_forces but it seems there are still some forces that move the plane.

If anyone has any idea, I feel like the solution is a combination of several override.

it doesn't disable them, it just doesn't apply sim/joystick/joy_mapped_axis_value to its mapped axis, you'll have to plumb that in yourself to.

Thank you very much, I hadn't thought about this dataref , I was using joystick/FC_ptch and others. It works now 🙂

Out of interest which DREFs are you using to update position (x,y,z) and rotation (phi,theta,psi) and do you use  XPLMWorldToLocal?  Currently experiencing challenges between the different frames of reference. Cheers.
