FAA ADS-B In ARCFAA ADS-B In ARC• I’m currently serving as Avidyne’s and one of GA’s representatives on
FAA’s ADS-B In Aviation Rulemaking Committee (ARC)s S at o u e a g Co ttee ( C)
• Follow on to ADS-B Out ARC which guided FAA’s mandate creation and public comment incorporation
• Committee’s charter is to “define a strategy for incorporating ADS-B In technologies into the National Airspace System” which couldinvolve guiding an ADS-B In Mandate.
• Other members include:
• Lobbying groups (NBAA, ATA, GAMA, AOPA, ALPA, NATCA)
• Airplane manufacturers (Boeing, Airbus)
• Avionics manufacturers (ACSS, Honeywell, Rockwell-Collins)
• Airlines (UPS, United, Continental, US Airways…)
• Government (FAA, DoD, NASA, MITRE, MIT)

• Final report due to FAA in September
What is ADS-B?What is ADS-B?
• Not “adds-bee” “A D S B ”• Not adds-bee , A. D. S. B.• Automatic
• Messages are sent out gperiodically without interrogation (unlike transponder)
• Dependent• Dependent on a position source
onboard the aircraft
• Surveillance-• Primary purpose is for ATC to
know where aircraft are
• BroadcastBroadcast• Messages are broadcast to
everyone not just sent to specific receivers

Dual LinksDual Links• FAA went with dual links in 2002 and confirmed in 2010 ADS-B Out rulemaking
for 3 principal reasons: 1. Frequency congestion on 1090 MHz (assumed 3x fleet growth from 2000 to 2025, problems with
even 2x fleet growth)
2. UAT avionics believe to be cheaper for GA (If 1090ES coupled with transponder, maybe, but UAT requires separate control head)q p )
3. UAT provided free weather to GA (before widespread XM/Sirius datalink weather)
• 1090ES1090 MH E d d S i ( f d li )• 1090 MHz Extended Squitter (same frequency as transponder replies)
• Mode-S transponder that sends out additional ADS-B information periodically in addition to replying to SSR and TCAS interrogations
Required above FL180 in US after 2020 and in Europe after 2017 for aircraft over 12 500 lbs• Required above FL180 in US after 2020 and in Europe after ~2017 for aircraft over 12,500 lbs
• International standard – may be required in Australia, Canada, Mexico, and elsewhere
• UAT• 978 MHz – less crowded frequency since not used by SSR and TCAS
• Synchronized CDMA – Code Division Multiple Access so requires precise (GPS) timing device
• Additional bandwidth for additional datalink data (e g FIS-B)

Additional bandwidth for additional datalink data (e.g. FIS B)
• Can share antenna with Mode-C transponder through coupler

ADS-B ApplicationsADS-B Applications
• ADS B Out Applications• ADS-B Out Applications• ATC services where there is no current radar
(e g Gulf of Mexico Alaska low altitude airspace(e.g. Gulf of Mexico, Alaska, low altitude airspace, radar failure/maintenance)
• Enhanced ATC services – ADS-B data is fused with radar and presented to controllers allowingwith radar and presented to controllers allowing faster update rates and position updates between radar sweeps
– Allow more efficient controller vectors– Earlier “radar contact” due to lower level ADS-B coverage
• Better ground surveillance at ASDE X airports• Better ground surveillance at ASDE-X airports• Improved last position data for search and rescue

PHL, SEA– Requires higher accuracy than
mandate– Line of sight issues
• In Trail Procedures (ITP)– Oceanic air carriers only
• Flight Deck Interval Management and Spacing (FIM-S) and Interval Management DelegatedManagement-Delegated Separation (IM-DS)

More Future Potential ADS-B ApplicationsMore Future Potential ADS-B Applications• Airborne Traffic Situational Awareness with Alerts (TSAA)
• TSAA is the next step beyond “Airborne” ADS-B application in providingTSAA is the next step beyond Airborne ADS B application in providing visual and audible alerts to pilots of threatening traffic.
• Uses ADS-B In information to create alerts for the pilot similar to TAS or TCAS alerts (no RAs), but improved based on more accurate ADS-B ( ), pdata and potentially a database of airports and runways
• Algorithm development is going to be focused on GA operating environment including in the traffic pattern and helicopter operations
• MIT with partner Avidyne received contract from the FAA to prototype, demonstrate, and draft standards for the TSAA application
• FAA funding because of the benefits for non-TCAS usersFAA funding because of the benefits for non TCAS users
• Schedule:• Application development and simulations: through 2011
• Flight tests and refinements: 2012
• MOPS and TSO published, available for all manufacturers: mid-2013
