Airfoil Performance Monitor for Iced Up Wings
I've recently come across some information about a device that measures the quality of the airflow on the lifting surface of an airfoil. It gives an accurate measure of the margin remaining to the stall in all conditions, whether clean or contaminated, and will even work on the takeoff roll above 60 knots to tell whether the wing is contaminated or not. Also works on a horizontal stabilizer to tell how close that is to a stall.
If interested in more information, please pm me.
