ABSTRACT:
An apparatus and method for wind debris detection comprises a spring loaded probe that is deployed on the leading edge of an aircraft wing into an area where debris formation might impact wing aerodynamic performance. The probe travel is sensed by sensors (angular displacement, linear displacement, proximity, torque, load cell on spring, and the like), and if the sensor(s) detect that probe travel is limited then presence of debris is indicated.
