This is true - when mounted conventionally on aircraft. For those new to aero (who might read this), remember that in motorsports we invert the airfoil because we want the opposite of what the fly-boys want. They would say we run our wings "upside down", because they want to generate lift (or bad things tend to happen). We want downforce (to make good things happen): low static pressure on bottom, high pressure on top.
