Automatic Dependent Surveillance Broadcast What are the benefits? How is it used? Timely and precise aircraft surveillance from GPS position information o Air Traffic Control has more precise view of controlled airspace o Operators can follow the paths of aircraft and ground vehicles o With ADS-B In, pilots are aware of nearby traffic and can receive ATM services Requires both airborne and ground infrastructure upgrades o Airborne Systems ADS-B Out: GPS (Global Positioning System) Source and ADS-B Transmitter/Transponder ADS-B In: Multi Function Display and ADS-B Receiver o Ground Systems ADS-B Ground Stations ATC Automation Integration Flight Following Systems Supports ground-based relay of complementary surveillance data 27.04.2016 2
The Technology 27.04.2016 3
ADS-B Technology: Link Options Mode-S 1090 ES (Extended Squitter) 1090 MHz (ICAO global standard) o Builds on existing Mode-S standards with additional information (the ES) o Required above 18,000 in the USA and at all flight levels internationally o Can be used in the USA below FL 180 UAT (Universal Access Transceiver) 978 MHz (USA only) o Cheaper installation than Mode S transponder for non-equipped aircraft o Reduces congestion on 1090 MHZ o Supports additional no-charge ADS-B In features (TIS, FIS, Graphical WX) o Currently operational only in the USA. and only below FL 180 VDL4 (VHF Data Link Mode 4) 108 137 MHz o Initially embraced in the research community but not supported by the aircraft and aerospace industries o ICAO standards exist for VDL4; Eurocontrol performance analyses (2010) have documented needed improvements prior to authorizing operational use 27.04.2016 4
ADS-B Technology: GPS Position Sources Four TSOs describe GPS position source performance Source: Honeywell In the US, operator groups have petitioned to use existing SA-Aware sources under waiver for some period following the 2020 mandate However, only SBAS/WAAS meets European/USA requirements without use of tools like the FAA s Service Availability Prediction Tool (SAPT) 27.04.2016 5
The Applications 27.04.2016 6
ADS-B In: Cockpit Display of Traffic Information (CDTI) Improved visual acquisition under VFR or MVFR conditions Situational awareness of runway occupancy VFR-like separation during IMC Enhanced VFR flight following Merging and spacing Self-separation or station keeping Enhanced visual approaches Closely spaced parallel approaches Reduced spacing on final approach Reduced aircraft separations Graphic Source: Airbus 27.04.2016 7
ADS-B In: Flight Deck Interval Management Provides precise inter-aircraft spacing, enabling increases in airspace throughput Increases throughput and enhances safety Opportunity to apply RNAV procedures (Optimal Profile Descents, or OPDs) Graphics Source: MITRE 27.04.2016 8
ADS-B In: Paired Approach Objective: Attain near-vmc arrival rates during IMC Aircraft must accurately report and maintain their planned final approach airspeeds (V app ) Safe window position indication and speed guidance aids pilot in in maintaining safe approach position Lead Aircraft ADS-B Out Closely Spaced Parallel Runways (>200 m) Blunder Zone Safe Zone Wake Zone Trail Aircraft ADS-B In Graphics Source: MITRE 27.04.2016 9
ADS-B In: In Trail Procedures (ITP) Allows ITP-equipped aircraft to safely maneuver between flight levels / tracks where procedural separation minima would otherwise constrain Breakout heading this type of operation and altitude fields Expected benefits o Reduced fuel burn o Reduced emissions o Passenger comfort o Enhanced safety Commanded Indicated Air Speed (IAS) Selected Target Flight ID Differential ground speed (positive values indicate overtake) IAS HDG ALT 180 UAL9123 DGS +30 Front Gate Spacing Goal (Green) Ownship (White) Rear Gate Graphics Source: MITRE 27.04.2016 10
ADS-B In: Merging and Spacing Provides visualization of merging and spacing operations Enhanced awareness of nature and wake characteristics of traffic Can provide speed guidance during final approach procedures Graphic Source: MITRE 27.04.2016 11
ADS-B In: Taxi Management Enhanced traffic awareness on the airport surface Anticipation of congestion in the non-movement area Management of collision risks with other aircraft and with ground vehicles Graphic Source: MITRE 27.04.2016 12
