Requirements Focus Group (RFG)
Overview:
The Requirements Focus Group (RFG) is a international
group consisting of members from the FAA, RTCA, Eurocontrol, EUROCAE,
and other interested parties. The RFG is operating as a joint
RTCA/EUROCAE activity. The primary object of the RFG is
to internationally harmonize operational concepts and minimum
safety and performance requirements for ground surveillance (GS) and
aircraft surveillance (AS) applications. These GS and AS
applications are defined in
Package 1 which lists initial applications to be implemented based
on the Principles of Operation for Airborne Separation Assistance
Systems (PO-ASAS).
To accomplish these objectives, the RFG will produce three (3)
documents for each application. This document suite will consist
of an Operational Services and Environment Description (OSED), a
Safety and Performance Requirements (SPR) specification, and an
Interoperability specification. The OSEDs will be developed by
the Application Description (AD) subgroup, while the SPRs are
developed by the SPR subgroup. (Both subgroups will contribute
to the Interoperability specification.)The
RFG activities are directly related to SC-186 and its work. Much
of the work done on the applications specified in the Aircraft
Surveillance Applications (ASA) MASPS will be used as a starting
point for the OSEDs and SPRs developed by the RFG. Further, it
is anticipated that the documents delivered by the RFG will be
published by RTCA/EUROCAE and be the basis for a joint revision of the
ASA MASPS.

official RFG web site hosted by Eurocontrol, or contact
Stuart Searight or
Jörg Steinleitner.

The document in the table below is the initial draft of the Safety,
Performance and Interoperability Requirements of the ADS-B-NRA
application. ADS-B-NRA stands for the provision of "Enhanced
ATS in Non-Radar Areas using ADS-B Surveillance," including the
provision of 5 NM separation services in related airspaces
(low/medium density). This document set specifying
the ADS-B-NRA application is to be published as a joint EUROCAE and
RTCA document, and others will follow which address other near-term
surveillance applications enabled by ADS-B. Since EUROCAE has
already defined a document structure and number (ED-126), the
document below uses the format of that EUROCAE document.
Before the initiation of the official WC/FRAC process, this document
is provided to a wider WG51/SC-186 community for an extended RFG
review and update process. The milestones of this process are
as follows:
- Deadline for provision of comments on the current version (V1.0)
- 12 January 2006
- Comment Resolution at RFG Meetings, 17 - 19 January 2006 at RTCA,
Washington DC
- Updated release during the 1st week of February 2006
- Deadline for provision of comments on the updated version - 9
March 2006
- Comment resolution at RFG Meetings, 20 - 23 March 2006 at
Eurocontrol HQ, Brussels
These two review cycles will result in a mature document set that
will be ready for EUROCAE WC and RTCA SC-186 Final Review and
Comment in the course of April/May 2006 in
preparation for a currently planned Joint Plenary 15-16 June 2006 at
RTCA.

ADS-B surveillance in non-radar areas
(Radar-like Services): One of the first applications being worked
on by the subgroups working on the OSED and SPR documents will be ADS-B in
non-radar areas (ADS-B-NRA), or radar-like services (RLS) as it is commonly
referred to in the United States. The work on this application will be
largely based on existing documentation of operational concepts and hazard
analyses done for the certification of equipment and operations in both Alaska
as part of the Capstone project, and Australia. Some of the documents on
which this RFG work will be based are made available through the following
table.
