For the purposes of 9E003.c., 'incidence angle' is the acute angle measured between the plane tangential to the aerofoil surface and the hole axis at the point where the hole axis enters the aerofoil surface. Aerofoil contamination including ice, snow, frost.	For the purposes of 9E003.c., incidence angle is measured from a plane tangential to the airfoil surface at the point where the hole axis enters the airfoil surface. We are essentially burning the airfoil as we fly it. like a blast furnace. 3,500 degrees Fahrenheit It's part of an airfoil. You want to fly one of these, you got to be familiar with airfoil, drag, lift, and thrust, and these are all principles of aerodynamics. At that speed, the surface of the airfoil is the temperature of molten steel
