Committee on Future Air Navigation Systems FANS which was tasked with studying identifying and assessing new. technologies including the use of satellites and making recommendations for the future development of air navigation. for civil aviation The FANS Committee determined that it would be necessary to develop new systems that would. overcome the limitations of conventional systems and allow Air Traffic Management ATM to develop on a global scale. 1 1 2 In September 1991 450 representatives from 85 States and 13 international organizations gathered at. ICAO Headquarters in Montr al Canada for the Tenth Air Navigation Conference to consider and endorse the concept. for a future air navigation system as developed by the FANS Committee that would meet the needs of the civil aviation. community well into the next century The FANS concept which came to be known as the communications navigation. surveillance air traffic management CNS ATM systems concept involves a complex and interrelated set of tech. nologies dependent largely on satellites, 1 1 3 The endorsement of the CNS ATM systems concept reached at the Tenth Air Navigation Conference. signalled the beginning of a new era for international civil aviation and paved the way for the many activities related to. the planning and implementation of new systems around the world. 1 1 4 The fourth meeting of the Aeronautical Mobile Communications Panel AMCP 4 Montr al April 1996. recognized the absence of objective criteria to evaluate communication performance requirements The objective criteria. needed were a set of values for parameters which would be based on the operational requirements for communication. systems in the various phases of flight The meeting agreed that there was an urgent need to assess the existing. technical options of communication systems against such a set of parameter values The term RCP type is used to. denote a set of values for these parameters, 1 1 5 When reviewing the report of AMCP 4 in 1997 the Air Navigation Commission tasked the Automatic. Dependent Surveillance Panel renamed in 2000 as the Operational Data Link Panel OPLINKP to develop the. operational concept of Required Communication Performance RCP. 1 1 6 In 2001 the OPLINKP completed its document entitled Concept of Required Communication Performance. and the Air Navigation Commission ANC solicited comments thereon from ICAO Contracting States The comments. received indicated broad support for the RCP concept In light of the comments received in 2002 the ANC amended the. OPLINKP work programme to develop a Manual on Required Communications Performance RCP and as necessary. Standards and Recommended Practices SARPS and procedures relating to the use of RCP in the provision of air. traffic services, 1 1 7 In 2003 the Eleventh Air Navigation Conference endorsed recommendations to.
a continue the development of SARPs procedures and guidance material on RCP and. b investigate areas for further work including determining the relationship of the RCP concept to. separation studies and interoperability standardizing RCP types and allocations ensuring the. 1 2 Manual on Required Communication Performance RCP. adequacy of air traffic service ATS functions and procedures for new CNS ATM environments as. well as establishing requirements for safety performance monitoring. 1 2 PURPOSE OF MANUAL, The purpose of this guidance material is to explain the concept of RCP identify RCP requirements applicable to the. provision and use of air traffic services and provide a basis for the application of RCP in a specified airspace. 1 3 EXPLANATION OF TERMS, The development and explanation of RCP rely on the understanding of terms which are included in Appendix A. OVERVIEW OF RCP,2 1 GENERAL, 2 1 1 The continuing growth of aviation places increasing demands on airspace capacity and emphasizes the. need for the optimum utilization of the available airspace These factors allied with the requirement for operational. efficiency within acceptable levels of safety have resulted in the need for a performance based airspace system. 2 1 2 The transition to a performance based airspace system is a critical aspect of the evolution to a safe and. efficient global air traffic management ATM environment As ATM evolves it will be necessary to ensure acceptable. operational performance taking into account changing technologies. 2 1 3 ATM is the aggregation of the airborne functions and ground based functions air traffic services airspace. management and air traffic flow management required to ensure the safe and efficient movement of aircraft during all. phases of operations, 2 1 4 ATM is achieved through the collaborative integration of humans information technology facilities and. services and is supported by communication navigation and surveillance capabilities that are dependent on each other. For instance the communication and surveillance capabilities and performance required to meet a given operational. capability which in this document is referred to as an ATM function will depend on the capabilities and performance of. the available navigation and other air traffic management functions including those on the aircraft Therefore to. determine the capability and performance requirements of the ATM system it will be necessary to consider the system. in its overall context taking into account all its interdependencies. 2 1 5 To meet the demands on airspace capacity and operational efficiency the operational communication. capability is playing an increasingly essential role in air traffic management using a mixture of data and voice. communication For example data link can provide for the integration of air traffic management functional capabilities on. the aircraft and at the ATS units and for more direct controller pilot communications enabling user preferred and. dynamic re routing and intervention capabilities in reduced separation environments where alternative communications. are more cumbersome, 2 1 6 The RCP concept provides a means to ensure the acceptable performance of communications within a.
complete ATM system,2 2 THE RCP CONCEPT, 2 2 1 The RCP concept characterizes the performance required of communication capabilities that support ATM. functions without reference to any specific technology and is open to new technology This approach is essential to the. evolution of operational concepts that use emerging technologies An ATM function is an individual operational. component of air traffic services Examples of ATM functions include the application of separation between aircraft the. re routing of aircraft and the provision of flight information. 2 2 Manual on Required Communication Performance RCP. 2 2 2 The RCP concept assesses operational communication transactions in the context of an ATM function. taking into account human interactions procedures and environmental characteristics. 2 2 2 1 The contribution of the human can be significant to RCP Communication is the accurate transfer between. sender and receiver of information which can be readily understood by both. 2 2 2 2 An operational communication transaction is the process a human uses to send an instruction a clearance. flight information and or a request and is completed when that human is confident that the transaction is complete. 2 2 3 The RCP concept is based upon operationally significant benchmarks which when attained assure. confidence that the operational communications supporting the ATM functions will be conducted in an acceptably safe. 2 2 4 The basis for the development of the RCP concept was the need for objective operational criteria in the. form of an RCP type to evaluate a variety of communication technologies Once these criteria have been set and. accepted a specific implementation of an ATM function including its technical and human performance may have its. viability assessed against acceptable operational criteria. 2 2 4 1 An RCP type is a label e g RCP 240 that defines a performance standard for operational communication. transactions Each RCP type denotes values for communication transaction time continuity availability and integrity. applicable to the most stringent operational communication transaction supporting an ATM function. 2 2 4 2 The RCP concept is not based on technology however it is not intended to promote an unrestricted. number of alternative communication technologies for one ATM function Whilst RCP types will be prescribed on the. basis of regional consultation within the ATM community so too will be the aircraft equipage requirements for. communications Interoperability and cost considerations will be major items to contend with during such consultations. 2 2 5 Several factors may affect States decisions as to when an RCP type will be prescribed These factors are. based on the ATM functions that an air traffic services ATS provider chooses to implement within that airspace In. cases where a safety related change including the implementation of a reduced separation minimum or a new. procedure is predicated on communication performance an RCP type should be prescribed The approval of this. change should include showing that the requirements and assumptions defined by the RCP type have been met. 2 2 6 It is anticipated that most aircraft operating in airspace for which RCP has been prescribed by States or on. the basis of a regional air navigation agreement will carry a mixture of voice and data communication equipment The. carriage of voice and data communication equipment may even be required in some regions or States to perform certain. ATM functions In order to receive approval to operate in such environments the combined communications equipment. should be required to provide at least the capabilities and features or their equivalents applicable to the appropriate. 2 2 7 Data communication capabilities allow for the integration of air traffic management functional capabilities to. exchange information between air traffic management facilities and aircraft For some ATM functions to comply with its. performance requirements it may be necessary to introduce data communication capabilities that allow for auto. 1 2 Manual on Required Communication Performance RCP adequacy of air traffic service ATS functions and procedures for new CNS ATM environments as well as establishing requirements for safety performance monitoring
