EUROCAE ED 227
MINIMUM AVIATION SYSTEM PERFORMANCE STANDARDS (MASPS) AeroMACS
|Publication Date:||1 September 2016|
PURPOSE AND SCOPE
This document contains the Minimum Aviation System Performance Specifications (MASPS) for an Aeronautical Mobile Airport Communication System (AeroMACS).
The purpose of this MASPS is to define the system performance requirements and to outline possible implementation options (architectures, use cases) for AeroMACS. In case relevant standards have not yet been developed (like for the IP addressing scheme), this document provides recommendations for further consideration in the appropriate standardisation bodies.
In addition to this MASPS, EUROCAE WG-82 has also developed other AeroMACS standards and in particular the AeroMACS Profile (ED-222) and the AeroMACS MOPS (ED-223) jointly with RTCA SC-223.
It is also noted that there is currently ongoing AeroMACS related standardisation activities in other groups (such as ICAO WG-S/WG-I, WIMAX Forum AWG and AEEC SAI), which are addressing aspects that may be relevant to the MASPS work such as the IP addressing scheme, the AeroMACS security framework, the avionics architecture and the AeroMACS network/architecture
Chapter 2 of this document provides a high-level description of the network model for AeroMACS, including the AeroMACS functional entities and reference points over which interoperability is achieved between functional entities.
Then different network implementation architectures for AeroMACS are discussed. This includes the whole end-to-end communication chain and deals with the ground and airborne architectural components as well. In that context, the IPv6 addressing scheme included in the ICAO ATN/IPS Manual is described.
Chapter 3 describes potential ATC and AOC applications for AeroMACS. In addition, it defines scenarios which have been used to validate performance requirements for AeroMACS.
Chapter 4 summarizes the AeroMACS operational requirements.
Chapter 5 summarizes the AeroMACS technical requirements.
Chapter 6 provides the QOS requirements for AeroMACS. In addition, a proposal for inclusion in ICAO Annex 10 for the mapping of AeroMACS classes of service over ATN message priority levels is outlined.
Chapter 7 gives an overview of the safety and performance requirements derived from EUROCAE WG-78 work. Therefore, the requirements are based on an end-to-end perspective. Regarding the functional entities of AeroMACS, as described in Chapter 2, safety and performance recommendations are also given in Chapter 7.
Chapter 8 addresses the aspects of radio coverage and capacity of the AeroMACS system.
Chapter 9 outlines the AeroMACS interoperability and compatibility requirements.
Chapter 10 provides information related to AeroMACS RF cell dimensioning and planning.
Chapter 11 outlines AeroMACS security requirements.
Chapter 12 describes a set of system level tests for IPv6, Ethernet CS, multicast and broadcast functions support, as well as an end-to-end test case. The end-to-end test case is similar to the one described in the DLS Community Specification  .
Appendix A outlines the list of acronyms and glossary of terms.
Appendix B gives more information about an AeroMACS capacity analysis conducted within the SESAR project P15.2.7.
Appendix C includes material from SESAR project P15.2.7 related to AeroMACS deployment case studies.
Appendix D describes the status of compatibility issues due to interference between AeroMACS and other radio systems at the time of publication of the present document.
Appendix E provides a topological overview of the Barajas airport, describing the Multiservice Network, the radio navigation aids and MLAT system cabling infrastructures.
Appendix F provides the list of EUROCAE WG-82 members.
