Abstract

Aircraft ^* and aircraft systems that operate in the National Airspace System ^† are required to be airworthy, ^‡ defined as being built to an approved design and in a safe condition for flight. The certification of an approved design for new or modified aircraft and aircraft systems is determined through a type certification ^§ process administered by the Federal Aviation Administration (FAA) via a show of compliance to the applicable Federal Aviation Regulations (FAR) under United States Code (U.S.C.) Title 14 Code of Federal Regulations (14CFR). Although there is not one specific regulation for the certification of human factors, the requirements to accommodate the human element in aircraft design are threaded throughout the FAR, hence, are a significant part of the type certification process.
