Any 3x3 vec (position 3, velocity 3, rotation 3) that would be more than that, a class specific to an aircraft, would be something much more. It would have position and velocity, and then it would have functions (getters, setters, or prediction functions). Something about the way OP said this was "a type" makes me very suspicious, because those raw values ought to be what you get when you poll the x vx rx ... of the type. If you're getting some sort of interpolation from that, it would obviously need to be from something which extended the type of an object in a certain position and attitude. The reason I'm saying this is that this is exactly where terrible feedback loops occur, when a type may return an altered version of its basic data when trying to access the basic data. If it's a type which has an underlying 3x3 vec and this type is specific to the aircraft so it has a bunch of overriding functions to operate on that data, that's fine, that's called a computer program. Not a specific type extending a vector.
