The future of ATS communications The future of ATS communications Presentation Transcript

  • Airports Future of ATS Communications Paul Ravenhill Technical Director Helios Air Traffic Management Space Telecoms Maritime Rail www.askhelios.com
  • ATS data link is currently used on the oceans and to a limited extent in core-Europe…. • Although data link has long been heralded as a key enabler for new operational concepts within ATM its use is largely confined to oceanic/remote services: • INMARSAT’s aero safety service has supported these services (based on FANS) for over 20 years • Europe is starting to use initial set of data link applications (CPDLC) within continental airspace • No other region uses or plans to use data link for continental ATS in the short or medium term 1 Aeronautical Conference 2011
  • Europe has a fragmented ATM system supporting high levels of traffic and complexity that require new solutions... http://vimeo.com/8690340 2 Aeronautical Conference 2011
  • This presentation uses three steps to describe the evolution of ATS services in Europe… • Step 1: Initial Data link Services • Step 2: Time Based Metering • Step 3: Full Trajectory Based Operations 3 Aeronautical Conference 2011
  • The first step is the initial data link services introduced by Link2000+ and the EC DLS mandate… • Implementing En-route CPDLC over ATN/VDL2 • Baseline ICAO standards • Forward compatible with new services/technology Operational 2013 2015 ACM – ATC Communications Management ACL – ATC Clearances ACM – ATC Microphone Check 4 Aeronautical Conference 2011
  • Step 3 supports SESARs goal of introducing trajectory based operations… • • • • • Performance driven Service orientated Trajectory based Integrates ASAS for sequencing Founded on SWIM Continuous Descent Approach AUTHORIZED RBT AGREED RBT CTA Current Position EXECUTED RBT 5 “The unique 4D description of the trajectory” Aeronautical Conference 2011
  • Using a single consolidated architecture… 6 Aeronautical Conference 2011
  • A trajectory is negotiated pre-flight, the ATM role is to enable the agreed trajectory… Departure Data link used to: • Ensure air and ground systems have a common agreement on the trajectory • Common information on the environment (e.g. MET, AIS, NOTAMS) Take -off 7 Aeronautical Conference 2011
  • In the en-route phase, aircraft fly direct routes to a precise 4d entry point to terminal airspace… Data link is used to: • Negotiate changes to the trajectory • Uplink and Downlink of environmental data • Agree approach procedure 8 Aeronautical Conference 2011
  • In the approach and landing phase, aircraft follow predefined paths with ASAS used to maintain separation… En-route Approach Data link is used to: • Select the path • Initiate ASAS procedures Landing 9 Voice communications will still be used to ‘vector’ aircraft in emergency situations Aeronautical Conference 2011
  • Step 2 is the bridge that will maximise benefits of a trajectory based approach using current technology… Initial Datalink Services Time Based Metering Full Trajectory Based Operations Types of service: • DLIC • ACM • ACL • AMC Types of service: • Initial 4D trajectory • FIS (D-ATIS, D-OTIS) • Advisory Services Types of service: • Full 4D trajectory • Delegated separation services • Extended FIS (D-ORIS) • Advisory Services When: Now When: 2015 to 2025 When: 2025+ Step 1 10 Step 2 Step 3 Aeronautical Conference 2011
  • The ICAO RCP Manual provides capability levels for specific operational environments for Steps 1 and 2… Continuity Integrity Availability 10 0.999 10-5 0.99998 60 0.999 10-5 0.9999 RCP120 120 0.999 10-5 0.9999 RCP240 11 Transaction Time RCP60 Oceanic Satcom RCP Type RCP10 Voice Service 240 0.999 10-5 0.9999 RCP400 400 0.999 10-5 0.999 Aeronautical Conference 2011
  • Future ATS datalink applications in Step 3 will require tighter Quality of service… Tighter RCP10 required? Continuity Integrity Availability 10 0.9995 10-7 0.99999 RCP*30 30 0.9995 10-7 0.99999 RCP60 60 0.999 10-5 0.9999 RCP120 120 0.999 10-5 0.9999 RCP240 240 0.999 10-5 0.999 RCP400 12 Transaction Time RCP10 Additional RCP for enhanced services RCP Type 400 0.999 10-5 0.999 Aeronautical Conference 2011
  • A multi-link environment will be required to achieve the required level of performance… Provides low latency requirements in TMA/En-route CS A d LD ban ial) (L estr r er T Ev Sa olve tco d m Oceanic Role plus support to high availability in continental airspace VHF Voice (retained as back-up) Supports high bandwidth services at gate 13 AeroMax (Airport WiFi) Aeronautical Conference 2011
  • Only some elements will need to be standardised for global interoperability… • Description of a “flight object” containing trajectorybased concepts • e.g. extension of the ICAO Flight Plan • Services for updating and synchronising the “flight object” • Including a language for describing and negotiating 4D trajectories • The data link applications will re-use these services: • The nature and timeliness will depend on the traffic density • Need to ensure common cockpit procedures • The QoS will be less strict in low density airspace 14 Aeronautical Conference 2011
  • The aeronautical satcom system will need to support “high” and “low” density services. • Next Generation ATM will use datalink to optimise traffic flows…but the applications may vary regionally. • Aero satcom needs to evolve to support new services, for example: • Global Service: RCP60 with 0.999 availability • High Density Continental: RCP60 with 0.9999 availability • When deployed, higher availability applications will require a multi-link environment. • Broadband support for voice, AOC and non-safety services will still dominate traffic profile 15 Aeronautical Conference 2011
