What is the meaning of pink line here?


I wonder this pink line’s meaning.

for the other colors, there is description in bottom of mission planner screen.

but for pink line, there is no descriptions.

where can I find the descriptions of this?

The pink line is the aircraft’s current orientation. You can observe it when a turn is made and if the airplane does not have a good tuning in roll it will be seen continuously.

Although, perhaps, rather than instantaneous orientation, it would be better to speak of a predicted trajectory.
