MSFS20 Teleport Workaround?

[AdventumSims]

Did anyone find a workaround for teleport in MSFS? It appears to be broken in its current state. I can teleport successfully to the proper location, but heading, altitude, speed, etc. is not retained.

For the RequestTeleportAction to work properly you need to specify a SimState file, which is just an .FLT file that defines state of the aircraft after the teleport. Variables you don't define in the SimState file will be filled in from the last used .FLT, usually the .FLT that loaded the flight. This means that after teleport, things like lights, flaps, and crucially simvars, will be reset to the state at the start of the flight.

The simvars contain the coordinates, altitude, orientation, speeds, and a variable called SimOnGround:

[SimVars.0]
Latitude=N37° 57' 15.09"
Longitude=W107° 54' 7.20"
Altitude=+015009.81
Pitch=-1.7961822304756200896
Bank=0
Heading=67.595765396585463236
PVelBodyAxis=0
BVelBodyAxis=0
HVelBodyAxis=0
XVelBodyAxis=-8.3283299715813328135
YVelBodyAxis=-12.848052061414350078
ZVelBodyAxis=465.00570101166533732
SimOnGround=False
OnPlatformHeight=-9999999999

The coordinates, altitude, and orientation can be defined by the RequestTeleportAction, but the speeds and SimOnGround will be reset to the start. So if the flight started on the ground and the teleport was in the air, SimOnGround will be reset to True, and the plane will be put on the ground immediately after teleport.

To fix this, you should use a SimStateFile. This is the configuration that worked for me:

        <SimMission.RequestTeleportAction InstanceId="{858FF2F5-D5DA-42D6-BB25-0DADB7204774}">
            <SimStateFilename>offground</SimStateFilename>
            <AttachedWorldPosition>
                <WorldPosition>N41° 1' 52.45",W113° 44' 27.00",+007000.00</WorldPosition>
                <AltitudeIsAGL>False</AltitudeIsAGL>
                <Orientation>0.000,0.000,145.000</Orientation>
                <IsOnGround>False</IsOnGround>
            </AttachedWorldPosition>
        </SimMission.RequestTeleportAction>

offground.FLT:

[SimVars.0]
SimOnGround=False
XVelBodyAxis=0
YVelBodyAxis=0
ZVelBodyAxis=200.000

This will make sure the plane doesn't teleport to the ground and has forward speed, but still reset things changed after spawn such as flaps, gear, and lights, but you can add them to the .FLT as well.

I don't think this is the best way for the teleport to work. I think it would be better it the RequestTeleportAction didn't reset variables to the state at the start, but kept them the same as immediately before the teleport.

PS: You can specify Airspeed in the RequestTeleportAction, but it didn't work properly in my experience.

Mr_LiamT,

Thanks for your knowledge and information once again. I'll try applying what you have written here and see if I have success. I haven't messed with Simvars too much yet, but I am learning (slowly) how to interact with the sim.

Thanks again,

Jeff
