Dynamic Soaring of Gradients or? See my Video Exp http://www.icarusengineering.com/Dynamic-Soaring-and-SE.htm I am trying to validate that the aircraft is indeed flying in 2 different air masses instead of just one rising air mass of a normal thermal. Using 2 types of gradients would define dynamic soaring apart from thermal soaring. I have posted a flight video of a personal aircraft in this experiment. I am hoping its dynamic soaring.
