In-flight icing’s hidden threat: the landing flare

by

Following uncontrolled collisions with the ground, hard landings are the second most prevalent outcome attributable to structural icing. Unlike the uncontrolled collision data, hard landing events are generally well documented; almost no one is fatally injured, and the sequence of events and aircraft response is pretty easy to map out. This set of data may give us a window into an obscure and overlooked aspect of aerodynamic icing… drag rise as a function of angle of attack.
