1.7 NASA Aircraft Icing Research for In-Flight IcingThe Aircraft Icing Research project supports the NASA AeroSpace Technology Enterprise's "Global Civil Aviation" pillar. The research efforts address the aviation safety goal of reducing accident rates due to icing hazards and the affordability goal of reducing the time and cost of designing and certifying deicing systems. These goals are accomplished by developing methods and tools as a foundation to provide information and technology solutions for the aviation system. Major technology elements of the Aircraft Icing Research project include icing weather information, icing simulation, icing effects, icing operations, and icing education and training.
The study of tailplane ice formation leads to better understanding of tailplane stall condictions and effective recovery procedures. Shown in the accompanying picture is an icing phenomenon known as tailplane icing, wherein ice accreted on the horizontal stabilizer causes it to stall and results in uncontrolled pitch, a situation that has led to fatal general aviation aircraft accidents. The joint FAA Technical Center and NASA Glenn program has identified the aerodynamic and handling characteristics of an aircraft in an ice-contaminated tailplane stall. Pilot training materials have been developed, based on the results of this investigation. The training video, which is targeted to pilots of general aviation and commuter aircraft, describes the tailplane icing phenomenon, defines the expected handling characteristics of an aircraft in a tailplane stall, and explains the recovery maneuvers pilots can perform.
