requirements. The MASPS will also specify the verification methodology to be used by
the regulatory agencies to certify an IPS implementation to support air traffic safety
services. In addition, the reader should consult the ARINC Specification 858 for avionics
implementation. [NOTE: ICAO Doc. 9896, ED. 3 and RTCA/EUROCAE IPS MASPS
are currently under development.]
Appendix A of this Profiles Document contains normative IETF RFCs to support the IPS
functional requirements specified in Section 3.0. These normative IETF RFC profiles were
derived from the NIST and DoD IPv6 profiles and represent the minimum set of IETF
RFCs that must be supported by each IPS Device Class, defined in Table 1-2. Optional
IETF RFCs are not included in Appendix A because the RTCA standards only specify the
minimum requirements for IPS. Vendors, OEMs and ANSPs may choose to implement
other additional IETF RFCs, as long as they do not impact the interoperability or
performance of IPS.
In general, the functional RFCs in Appendix A are mandated in their entirety. However,
the detailed IETF requirements for each RFC may not be applicable for all device classes
in IPS. As such, Appendix B identifies detailed profiles for each of the IETF RFCs
mandated in Appendix A where an exception is required for IPS. Appendix B is normative
Establishment of SC-223/WG-108 – Terms of Reference
As Internet Protocol (IP) standards mature and current communication technologies are
upgraded, or new systems are developed, a move to IP-based communication becomes a
more viable and attractive alternative to existing technologies. Enterprises can begin to
leverage the benefits stemming from a unified IP based communications strategy including
greater network flexibility due to better scalability and ultimately better performance.
The Aviation Industry’s planned end-state has recently been identified as one based on
Aeronautical Telecommunications Network – Internet Protocol Suite (ATN/IPS)
standards. ICAO has planned to adopt the IPS standards for future aeronautical datalink
communications to enable seamless, broadband, end-to-end communications.
FAA Management has directed that the existing ICAO Document 9896 ed.2 published in
2015 be updated to complete the air-ground IPS requirements and to develop the
corresponding A-G IPS Profiles and Minimum Aviation System Performance
Specification (MASPS) documents in RTCA. All future FAA Aviation systems, including
System Wide Information Management (SWIM) and Unmanned Aircraft System (UAS)
Command & Control (C2) Beyond Line-of-sight (BLOS) networks, can then be designed
and developed leveraging these new communication standards to enable more effective
and efficient sharing of data.
Following the schedule for the ATN/IPS deployment worked between US and Europe,
EUROCAE also created WG-108 to provide a guidance document for ATN/IPS
certification and deployment in Europe.
RTCA SC-223 and EUROCAE WG-108 decided to work together as approved by the PMC
and the TAC on joint deliverables to ensure IPS consistency over US and EUROPE. The
joint group will develop:
IPS MASPS on IPS end-to-end interoperability and certification,
Based on the scope defined in the MASPS, the IPS profiles will leverage the IETF RFCs
and their updates. However, aviation specific requirements will be addressed in the detailed
profile. In addition, the MASPS will contain region-specific requirements, beyond the
