BACKGROUND:
There are a number of potential benefits that FAA customers (e.g., airlines and the flying public)
and service providers (e.g., air traffic controllers) can realize with the use of ADS-B technology
and associated applications. Over 70 ADS-B operational capabilities have been identified that
could provide benefit if implemented and provided as a tool for flying public use. These benefits
include enhanced safety, increased aviation efficiency and the potential to increase the capacity
of all air and ground space used by the aviation industry. To satisfy the need for providing the
ADS-B capabilities, SC-186 has been established to recommend industry standards for ADS-B
applications that can be made available to governments, industry and other organizations.
Version update releases are planned to support the phased operational implementation of ADS-B
applications.
The activities of Special Committee 186 are directly traceable to the NextGen Operational
Concept.

SCOPE:
RTCA Paper No. 013-10/PMC-859
December 8, 2010
Special Committee 186 (SC-186) shall codify operational requirements based upon the airborne
and ground user needs for an Automatic Dependent Surveillance-Broadcast (ADS-B) system.
The development activities of SC-186 shall consider the relevant work of other bodies, including
ICAO Panels, FAA/CAAs, EUROCAE, AEEC, SAE, and other RTCA Special Committees.
The Special Committee should coordinate with these bodies, including the EUROCAE and
ICAO representatives. SC-186 shall also consider the recommendations developed by RTCA
Task Force 2, 3, 4, and 5.
ENVISIONED USE OF DELIVERABLE(S)
MOPS published by SC-186 are intended to be used by the FAA and other civil aviation authorities
(CAAs) as an acceptable means of certifying ADS-B equipment for civil aircraft. Additional documents
from SC-186 may form the basis of advisory material for certification authorities, and may inform the
operational approval process and safety risk management directives for the FAA and other CAAs.
Specifically, the deliverables above are intended for the following purposes:
ASAS MOPS: provides equipment specifications for ADS-B surveillance processing, applications
processing, and display requirements for Cockpit Display of Traffic Information. Intended to result in a
TSO for manufacturers of this equipment.
ATSA-SURF SPR: Safety and Performance Requirements document for the use of ADS-B for
situational awareness in a surface context. Jointly developed with EUROCAE WG-51, this document
will form part of the basis for a joint ASAS MOPS.
APT SPR: Safety and Performance Requirements document for the use of ADS-B for ground
controllers. Jointly developed with EUROCAE WG-51, this document may have implications for
performance requirements for the ground system, which could be considered by the FAA in future
revisions of the ground system specifications.
SURF-IA SPR: Safety and Performance Requirements document for the use of ADS-B for indications
and alerts to flight crews on the airport surface. This document will form the basis for a future revised
version of the ASA MASPS and ASAS MOPS.
IM SPR: Safety and Performance Requirements document for the use of ADS-B for managing air-toair
spacing in various contexts. Jointly developed with EUROCAE WG-51, this document will form part
of the basis for a joint ASAS MOPS.
ASA MASPS: System requirements document that partitions requirements from SPR documents into
link and platform MOPS requirements, forming the basis of requirements for platform and link MOPS
(DO-317, DO-282, and DO-260).

SPECIFIC GUIDANCE:
The committee should:
RTCA Paper No. 013-10/PMC-859
December 8, 2010
1. Working jointly with EUROCAE WG51, harmonize operational concepts and perform highlevel
safety, performance and interoperability performance analysis for well-defined aircraft
surveillance (AS) and ground surveillance (GS) applications including the near-term
applications specified in Package 1. While the initial set of ASA applications were being
refined within RTCA, other activities in Europe were developing similar operational
concepts. To facilitate global interoperability, harmonization of these applications is needed.
This work will be done as a joint RTCA/EUROCAE activity. The efforts will be based both
on the methodology specified in RTCA DO-264/EUROCAE ED-78A, and on previous work
done within RTCA and in Europe. The work products of these efforts will be documents
addressing the entire set of applications that include the following:
� Operational Services and Environment Description (OSED),
� Safety and Performance Requirements
� Interoperability assessment.
It is anticipated that this document set will be the basis for revising the ASA MASPS
(RTCA/DO-289) as a joint RTCA/EUROCAE document. Other results from this work will
be the harmonization of the analysis methodology most appropriate for surveillance
applications and applications definitions in a format that can be useful to stakeholders in the
U.S., Europe, and elsewhere.
2. Update the December 9, 2003 MASPS for Aircraft Surveillance Applications (ASA)
(RTCA/DO-289), including detailed application descriptions and end-to-end requirements
analysis. This revision of the MASPS will address the initial ASA applications and some of
the other ASA applications defined jointly by SC186 and EUROCAE WG51 within the
Requirements Focus Group (RFG). DO-242A will be superseded by DO-289 with all
relevant material from DO-242A being incorporated into DO-289.
The revision of the ASA MASPS will be developed jointly with EUROCAE WG51, and will
be the repository for applications descriptions and requirements for airborne surveillance
applications. Beyond the specific applications addressed in the initial ASA MASPS and
those defined by the RFG, future versions of the ASA MASPS should include additional
applications that are of interest and benefit to the aviation community. Oceanic in-trail
procedures is one example of a beneficial application that is expected to be included in the
next version of ASA MASPS.
The application descriptions in the ASA MASPS should have sufficient detail to ensure a
common understanding of the applications by all interested parties and should remain
consistent with the definitions agreed to within the OSEDs developed through RFG

activities. The MASPS should follow the process articulated in RTCA DO-264,
appropriately tailored by RTCA SC-186 for surveillance applications, for the assessment of
applications, analysis of safety, and allocation of requirements. The MASPS should allocate
requirements to ASA subsystems, including ADS-B, TIS-B, surveillance processing, alert
functions, supporting applications processing, and displays.
3. Update and maintain, as required, Minimum Operational Performance Standards (MOPS)
for an ADS-B system operating on 1090 MHz frequency (RTCA Document No. RTCA/DO-
260[]).
4. Update and maintain, as required MASPS for Traffic Information Services Broadcast (TIS-
B) (RTCA Document No. RTCA/DO-286[]). The TIS-B MASPS shall provide
recommendations for the transmission of ground-derived surveillance information on aircraft
and vehicles to suitably equipped users for display and use in airborne and surface
applications. TIS-B compatibility and interoperability with ADS-B applications must be
addressed.
5. Develop and maintain, jointly with EUROCAE WG-51 MOPS for Airborne Separation
Assistance Systems (ASAS) , RTCA DO-317[]. Note that SC186 is tasked only with
developing standards related to the traffic display. SC186 is not authorized to make any
changes to DO-185[]. Any changes that are determined to be required to DO-185A shall be
coordinated through the RTCA Program Management Committee.
6. Update and maintain, as required, Universal Access Transceiver (UAT) ADS-B MOPS
(RTCA Document No. RTCA/DO-282[]).
7. SC-186 shall serve as RTCA’s forum for the consideration and initial development of new
ADS-B ground and air-based surveillance applications enabled by ADS-B. SC-186 will
solicit application inputs from within and outside SC-186. Upon receiving application inputs,
SC-186 will review and consider the application for further development. Considerations
will include maturity of concept, potential timeframe in which the application might become
operational, number of stakeholders, and compatibility with ADS-B implementation
planning. The committee shall develop and publish procedures for prioritizing applications.
8. Coordinate closely with other government and industry groups, as appropriate, e.g.,
EUROCAE, ICAO, as well as with other RTCA special committees and working groups
including, for example, SC-147, SC-159, SC-206, SC-214, and SC-217. Coordinate an
Inter-Special Committee Requirements Agreement (ISRA) with SC-206 for the potential use
of ADS-B to transmit weather and other parameters for wake vortex and traffic flow
management applications.
