## Abstract

This action amends the airworthiness standards for transport category airplanes concerning the airspeed indicating system. It adds airspeed indication requirements for speeds greater than and less than the speed range for which airspeed indication accuracy requirements currently apply; a requirement that airspeed indications not cause the pilot undue difficulty between the initiation of rotation and the achievement of a steady climbing condition during takeoff; and a requirement to limit the effects of airspeed lag. This amendment eliminates regulatory differences between the airworthiness standards of the U.S. and the Joint Aviation Requirements of Europe, without affecting current industry design practices.
