Optical Ice Sensors for UAVs

The perverse thing about ice on the tailplane of a general aviation aircraft is that the pilot sits and looks forward, but the tailplane is aft. You can’t see it from the cockpit.

The formation of ice over lifting surfaces can affect aerodynamic performance. In the case of helicopters, this loss in lift and the increase in sectional drag forces will have a dramatic...
