The part 23/25 in the title of this section refers to Federal Aviation Administration (FAA) and European Aviation Safety Administration (EASA) (formerly Joint Aviation Administration) definitions of aircraft types. Part 23 aircraft are defined as normal, utility, acrobatic, and commuter category airplanes; part 25 defines transport category airplanes. The discussions in this section are applicable to part 27 (utility helicopters) and part 29 (transport helicopters) as well as military installations. The systems in this section have, for the most part, been developed for the general and commercial aviation market, or mandated for use by the state authorities. The emphasis is on compliance with the applicable certification requirements and sometimes spent on the civil certification process, its history, and a review of the types of documents that you will need to reference. The discussion continues with hardware, software, and safety considerations and the requirements for each. Controls and displays and human factors, which are considerations for all test plans,were discussed in detail and documents to assist in the test planning process will be identified. The systems which are covered include weather radar, global positioning system (GPS) civil certifications, reduced vertical separation minima (RVSM), terrain awareness warning systems (TAWSs), traffic alert and collision avoidance systems (TCASs), flight management systems (FMSs), landing systems, autopilots, and integrated navigation systems.
