Improved Standards for Determining Rejected Takeoff and Landing Performance

This action amends the airworthiness standards for transport category airplanes to: revise the method for taking into account the time needed for the pilot to accomplish the procedures for a rejected takeoff; require that takeoff performance be determined for wet runways; and require that rejected takeoff and landing stopping distances be based on worn brakes. The FAA is taking this action to improve the airworthiness standards, reduce the impact of the standards on the competitiveness of new versus derivative airplanes without adversely affecting safety, and harmonize with revised standards of the European Joint Aviation Requirements-25 (JAR-25). These standards, which affect manufacturers and operators of transport category airplanes, are not being applied retroactively to either airplanes currently in use or airplanes of existing approved designs that will be manufactured in the future.
