This may be a case of my airplane pilot's mind screwing with my feeble brain but ........ when I am looking at a telemetry file and it says Yaw: 159 degrees, what is that telling me? Based upon the direction the green pointer is headed it appears to be the direction the drone is headed. If so, why are we not calling this a compass heading instead of yaw? I I think most airplane pilots would agree that if you are yawning 159 degrees you are in serious trouble. Explanations appreciated.
