SC-222, Inmarsat AMS(R)S was established<br />

at the request of Inmarsat to define system level<br />

requirements and equipment specifications<br />

for the production of “Technique Specific<br />

Appendices” to revised DO-270, DO-262 and<br />

DO-210, as necessary, to add safety service<br />

capability to SwiftBroadband. SwiftBroadband<br />

is Inmarsat’s latest generation aviation<br />

communications service.<br />

SC-221, Aircraft Secondary Barriers was<br />

established at the request of the FAA to develop<br />

guidance for aircraft secondary barriers and<br />

alternative flight deck security procedures. The<br />

guidance is expected to address common design<br />

characteristics, minimum performance criteria,<br />

installation guidance, and approval certification<br />

guidance for Installed Physical Secondary<br />

Barriers (IPSBs).<br />

SC-220, Automatic Flight Guidance and<br />

Control Systems (AFG&CS) was established<br />

at the request of the FAA to develop MOPS<br />

and installation guidance for AFG&C systems.<br />

Aircraft operators are increasing equipage of<br />

AFG&C systems in support of safe and efficient<br />

flight operations. The MOPS and installation<br />

guidance will be used to support AFG&C equipage<br />

of a wide variety of aircraft types including<br />

transport category airplanes, small business jets<br />

and commuters, small airplanes, and rotorcraft.<br />

SC-219, Attitude and Heading Reference<br />

Systems (AHRS) was established at the request<br />

of the FAA to develop MOPS for Solid-State<br />

Strap-Down Attitude and Heading Reference<br />

Systems (AHRS). The designs of the majority<br />

of the mechanical gyroscopes used in general<br />

aviation were created in the 1950s or before<br />

and have significant operational, performance,<br />

and failure mode properties relative to current<br />

technology. Low-cost AHRS based on solid-state<br />

technologies have started to replace conventional<br />

attitude and heading instruments to increase<br />

their reliability and accuracy. The MOPS is<br />

expected to address system performance, failure<br />

conditions, and environment testing requirements<br />

not covered in current guidance.<br />

SC-218, Future ADS-B / TCAS Relationships<br />

was established as recommended by<br />

the <strong>RTCA</strong> PMC to develop an in-depth report,<br />

Assessment, Operational Concept, and Recommendations<br />

on the Future Relationship Between<br />

ADS-B and TCAS. SC-218 shall assess the needed<br />

relationship between TCAS and ADS-B in the<br />

National Airspace System (NAS) in the period<br />

2020-2025, taking into consideration anticipated<br />

air traffic density in that time frame. This committee<br />

was inactive and did not meet during <strong>2009</strong>,<br />

pending further direction from the Program<br />

Management Committee.<br />

SC-217, Terrain and Airport Databases was<br />

established at the request of Jeppesen to update<br />

the documents DO-272, Industry Requirements<br />

for Airport Mapping Databases for Aeronautical<br />

Use, and DO-291, Terrain and Airport<br />

Mapping Database Exchange Standards, to<br />

include requirements identified in related standards<br />

documents including ARINC 816-1 and<br />

AIXM 5.0 and to update the standard that defines<br />

the exchange of this information between<br />

governments, data providers, and data integrators.<br />

The updated DO-272B and DO-291A were<br />

both published during <strong>2009</strong>.<br />
