Presentation Transcript

  1. Overview • Support to NCAR for Transoceanic Aircraft • Framework to Address the Support • Engineering and Technical • Human Factors • WTIC Program Overview • Summary

  2. Inflight Display of Hazardous Weather for Transoceanic Aircraft • Technical Performer: NCAR Boulder, CO • Key Tasks • Evaluate the usefulness of an uplinked, satellite-based product that outlines the 30kft and 40kft convective cloud top heights in a two-hour look-ahead display focused on the aircraft position and flight direction • Evaluate uplinking Global Graphical Turbulence Guidance (GTG) Product • Outcomes • Evaluation of in-flight display for Pacific Ocean transoceanic flights between California and Australia • Evaluation of the in-flight display product by adding turbulence information derived from the Global GTG • Evaluation of transoceanic flights into the Gulf of Mexico/Caribbean/South America regions and to Atlantic flights to Europe/Africa • Evaluation of in-flight convective cloud tops height and Global GTG on Electronic Flight Bags

  3. Schedule • Initial Planning Dec 2010 • Display for real-time ASCII cockpit images for datalink (ACARS) • Create draft Flight Crew Bulletin • Pacific Ocean transoceanic flights between California and Australia • Expand Evaluation Dec 2011 • Add transoceanic flights to the Gulf of Mexico/Caribbean/South America regions & to Atlantic flights to Europe/Africa • EFB Graphical Demonstrations Dec 2012 • Color graphics displays overlaid with flight path & aircraft ownship position • Industry supported broadband datalink (Airborne SWIM)

  4. Three Components of Framework

  5. MET Information Delivery Systems

  6. MET Datalink Systems Characteristics

  7. Datalink Assessment • Technical Performer: KIHOMAC Inc • Key Task • Assess NAS datalinks signal latency, bandwidth, and quality of service capability to disseminate MET information to the flight deck within the NAS • Aircraft equipage requirements to support the transmission and receiving of the ADS-B, VHF Digital Link Mode 2, Iridium Global Network, and Inmarsat Swift Broadband links • Outcomes • Network simulation with transmitter, receiver and link models to assess the bandwidth availability, geographic coverage, latency, reliability, and quality of service for graphical icing products and graphical turbulence products dissemination using ADS‑B, VHF Digital Link Mode 2, Iridium Global Network, and Inmarsat Swift Broadband links • Three separate geographical/air traffic scenarios to compare coverage and availability in three zones: Washington, DC – New York City corridor; Rocky Mountain region (Denver); Polar region

  8. Schedule • Briefing & Model 90 Days ACA • Final Report 180 Days ACA • Bandwidth requirements, signal latency at flight levels 1,000 to 50,000 feet mean sea level at 1,000 feet intervals for coverage areas • Final Report 270 Days ACA • Aircraft equipage requirements to support the transmission and receiving of the ADS-B, VHF Digital Link Mode 2, Iridium Global Network, and Inmarsat Swift Broadband links

  9. MET Presentation • Five HF Perception design issues • Presentation format (graph, text, 2-D, 3-D) • Map Orientation (north-up or track-up) • Degree of clutter • Availability of geographical scale • Color use • Five HF Cognition design issues • Veridicality and realism of display • Support mode awareness • Provide uncertainty information • Provide predictive aiding • Temporal and spatial resolution

  10. MET Symbology (SAE G10) • Technical Performers • Industry & Government (Boeing, Airbus, Jeppesen, Honeywell, WSI) • Key Tasks • Develop guidance and standards for the electronic presentation of MET info • Identify gaps from review of current standards • Identify and define MET products and symbology set • Develop Cockpit Display of datalinked weather info • Outcomes • Standardized Met Symbology Set • Symbology for Validation • Aerospace Recommended Practice 5740, Cockpit Display of Datalinked Weather Information

  11. MET Symbology Schedule: Initial HF Planning June 2010 Support Facilities Planning August 2010 Complete Support Facilities FY2011 Develop Algorithms for Symbology FY2011 Develop Human-Machine Interface FY2011 Conduct Evaluation FY2012 Harmonize with NextGen HF ATM/SESAR TBD Final Report: FY2013 Project Status: MET products and symbology set defined (Feb 2010)

  12. WTIC Outreach Partners • Universities • University of Oklahoma • National Institute of Aerospace • Embry-Riddle Aeronautical University • University of Alaska • University of North Dakota • Professional Societies • IEEE • SAE • Government • FAA Aircraft Safety • NASA, Glenn • NASA, Langley • CAMI • NCAR • International • Eurocontrol • RTCA Air Carriers, OEMs, and Avionics Manufacturers – TBD

  13. Summary • Support transoceanic aircraft with MET products that enhances safe and efficient decisions during adverse weather conditions • Provides for aircrew situational awareness of transoceanic weather hazards • Evaluations will identify opportunities to enhance the MET capabilities to support transoceanic aircraft
