RTCA DO-221 RTCA Document 221, Guidance and Recommended Requirements for Airport Surface Movement Sensors, Issued 4/94. Provides recommended standards for both sensor and system characteristics. The primary purpose for these sensors is to operate stop bars located on taxiways which provide entrance to low visibility runways. The sensors may also be used for other low visibility functions such as taxiway light sequencing, runway exiting notification and presence detection. RTCA DO-222 RTCA Document 222, Guidelines on AMS.S Near-Term Voice Implementation and Utilisation, Issued 4/94. Contains operational guidelines and recommendations for the implementation and utilisation of Aeronautical Mobile Satellite (Route) Services, voice communication functions in the near-term (circa 1993-1996) air traffic: environment. It presents a system-level view of how satellite voice services can be implemented and used in the Air Traffic Services (ATS) and Aeronautical Operational Control (AOC) environments inclusive of aircraft installation requirements, ground infrastructure requirements and available AMS(R)S services. This document defines the functions and performance needed to facilitate the development, implementation, certification and operational use of satellite voice in an environment where satellite voice communication is not yet a required capability for air navigation. It uses as its basis the existing standards for satellite voice and ground equipment. RTCA DO-223 RTCA Document 223, Minimum Operational Performance Standards for Context Management (CM) Equipment, Issued 7/94. Identifies aircraft equipment requirements to support the forwarding of addresses, such as "log-on", between aircraft system and ground systems. Context management will support Air Traffic Services communications, such as ATC Two-Way Data Link communications, Automatic Dependent Surveillance, and Flight Information Services, as well as satellite voice and Aeronautical Operational Communications. Broadcast communications will probably not use context management. RTCA DO-224 RTCA Document 224, Signal-in-Space Minimum Aviation System Performance Standards (MASPS) for Advanced VHF Digital Data Communications Including Compatibility with Digital Voice Techniques, Issued 9/94. Contains three major sections. The introductory section provides VHF system characteristics and presents the principles of operation of the current VHF voice and data system, and the proposed future system. The aviation user section identifies the users of the systems and describes the expected availability and integrity of the avionics. The technical characteristics section describes the new system. Both packet and circuit modes of operation are defined. This document also includes a tutorial on aspects of VHF communication system design. |
