Approved by ASTM International's Committee on General Aviation Aircraft (F44), 2 new standards cover handling characteristics and icing protection. Specification for Handling Characteristics of Aeroplanes (F3173/F3173M) establishes airworthiness design standards for general handling characteristics in flight, on ground, and on water, while Specification for Icing Protection for Small Airplanes (F3120/F3120M) gives manufacturers defined path to meet regulatory requirements.
