UE5 JSBSim plugin has the initialization stage written in c++. I'm not sure you can currently make it work with that method of nodes. That being said, the plugin already has a variable to set the initial calibrated airspeed in the JSBSim component. You can set it in the blueprint or in the level editor details if the blueprint is placed in the level. As for setting initial altitude, you can set the Z height in UE5 for the blueprint. 1 unit equals 1 cm. So 100000 units in Z equal 1km in altitude. |

It probably crashes because the property isn't loaded yet. JSBSim has to load first. And I found getting/setting properties through command console too early can cause crash. |

Yes it's some problem/unexpected behavior with this section. These commands you can set them in the main blueprint instead of the level editor. |

But anyways when the Command Console node crashes, it's because the property doesn't exist or it's read only. In this case it look like there is an extra blank space in front of the first string of
ic/h, which will crash the engine, because "_ic/h" doesn't exist.That being said, the plugin already has a variable to set the initial calibrated airspeed in the JSBSim component.
