This is an approximation that only works in steady conditions. It over-reports any spikes in aircraft rotation velocity, so I would use some kind of damping function with it.
If assuming a "normal" plane, car, etc. (no hovering or drifting/PSM), then x- and y-components of velocities are small ==> velocity = z-component.
Finally, for planes, assume z-component is always positive, so we can just use GS.
Idk how to get velocity components in a way that isn't affected by wind, or that requires very long formulas and suffers from floating point loss of significance. But i guess you can assume wind speed is small as well
.
Static rotational component (by convention, positive when gravity acts against that direction)
x: cos(PitchAngle) * sin(RollAngle)
y: cos(PitchAngle) * cos(RollAngle)
z: sin(PitchAngle)
Magnitude of the static rotational component will always be 1 (or Newton will break your kneecaps)
.
Dynamic rotational component (positive when centripetal acceleration is in that direction)
x: GS * YawRate * (pi/180) / 9.81
y: GS * -PitchRate * (pi/180) / 9.81
z: 0
(If you have individual components of GS, you will find that each component is affected by two GS-rotation pairs)
.
Translational component
(If you have the individual components, you should use them)
x: 0
y: 0
z: rate(GS) / 9.81
@ToeTips
The conveyor belt causes a very small acceleration of the plane in the direction of the conveyor belt due to rolling frictional force, assuming the brakes are off. This is true for either direction.
.
Thrust is the main factor of acceleration and will easily overcome this friction, just like it does on a plane on a normal runway.
.
Tip: draw a free body diagram
I assume that the rolling resistance between the plane and conveyor belt is constant and small compared to thrust. The conveyor belt will have almost no effect.
.
If you can put a car in neutral at low speeds, where drag is very small, the acceleration will mostly be from rolling resistance.
.
If you put a plane with brakes off on a conveyor belt and gradually start the conveyor belt from rest, the plane should accelerate very slowly from rolling resistance. The acceleration is in the direction that the conveyor belt is moving.
.
If the conveyor belt is moving forwards, you can apply the brake to reach the same speed as the conveyor belt without using the engine.
.
If the conveyor belt is fast enough, you can approach takeoff speed, but rolling resistance (and friction during braking) are proportional to normal reaction force of the belt on the plane, which is equal and opposite to weight of the plane on the belt. The normal force will be zero somewhere around takeoff speed, so speed is asymptomatic at the takeoff speed (if drag is ignored). You cannot exceed the takeoff speed unless you do something that reduces lift first, like pitching down or retracting flaps.
.
The above paragraphs assume that air is static. If you want to consider it, there should be a small effect from the no-slip property of fluids, where the air touching the belt moves at the same speed of the belt. This will affect the takeoff speed if the conveyor belt is fast enough, and the wings are low enough.
.
Conclusion: You can still take off if you have thrust, but not if you have no thrust

Settings: Set JointRotator.speed to a large number
FT: Some hints:
- Use the sum function - sum(speed) to control the rotator
- Argument speed: Use the magnitude of wheel rpm multiplied by some constant (you will need to find this yourself as it is build-specific)
- It is the same FT as custom wheel rims

The video might be made in response to recent events, but it's about a problem about the community that has been around since early SP, so it doesn't have a strong feeling of making fun of an incident too soon. However, it's not clear if tcg is on either side (I don't know them). It is also a common meme format.
If the build is targeting your aircraft, yes. The FT deltaangle(Heading,TargetHeading) and deltaangle(PitchAngle,TargetElevation) gets the angle an aircraft needs to rotate to face the target.

@DDVC i never had builds spawn clipping into the tracks before, so i don't know about that issue
My trains don't have any dummy parts. Just make sure the wheels are low enough from the fuselage blocks on the bogies. But the spawn could be controlled by my wheels, which have a size of 1 but are scaled down to 0.3x. This is changed slightly from winterro's Brighton Class example build for SPR.
The stop markers have dummy parts to center the build in the designer and simulator. I think AI aircraft always spawn with the cockpit block in the same place.
