Tim Rahmes The Boeing Company Turbulence Workshop Perspective from Boeing
Agenda • Needs, benefits and vision • Industry standards development • Value of flight testing • Uplink • Downlink • Integration • Summary
From RTCA DO-340: Concept of Use for Meteorological and Aeronautical Information Uplinked AIS Uplinked Weather Benefits: • Increase situational awareness • Reduced fuel & emissions • On-time performance • Passenger ride comfort • Reduced injuries • Reduced maintenance • Reduced pilot/controller workload Weather Displays • Convective weather • Turbulence avoidance/alerts • Winds/temps aloft • Volcanic ash • Icing • Lightning • SIGMETs • AIREPs/PIREPs • RVR, runway conditions • etc. Graphical and Database Needs • NOTAMs (e.g. TFRs, SAA) • FM, AMM, EGPWS, EFB, etc. • NextGen Compatibility • Applicable to time-limited non-weather constraints (e.g., traffic congestion) Benefits w/observations advancements: • Better weather forecasts • Capacity increases likely • Atmospheric modeling contribution • Environmental constraint mitigation Increased use of aircraft as sensor platform • AMDAR parameters (e.g., wind, T, EDR turbulence, water vapor, icing) • Future needs (e.g., HIWC needs) • Near real time data needs of sensed data in flight deck (e.g., wake turbulence, wind-shear events) Potential real-time sharing of in situ observations • To flight deck (e.g., wake turbulence, windshear events) Crosslink Weather Downlink Weather
The Vision (Turbulence in Air Transport) Today ATC communicates with aircraft via voice, although ACARS and FANS / CPDLC have made significant inroads in recent years Dispatch use of ACARS is airline dependent (both uplink and downlink meteorological/turbulence) Future key differences Near-term: Broadband links will be used to communicate strategic weather data to flight crews. New information management architectures will be used. Mid-term: Increased aircraft wx/turbulence observations, enabling improved forecasts and nowcasts. Continued adoption of onboard weather radar for tactical planning. Longer-term: Data linked AIS & MET information may be used for “controlling, safety-critical functions” -- not just for “advisory” purposes New Data Links Paper PIB Today’s ACARS
Need: Beyond Ellrod. Integrate multiple inferences into a combined forecast / nowcast product • Mountain waves Tropopause folds Convective • Desire is an integrated display of turbulence: • Thermal • Mechanical • Shear Transverse bands Desire a combined inference

Boeing ecoDemonstrator flight test program Goals Accelerate technology for more fuel efficient, cleaner, quieter, advanced materials Faster innovation to application-ready technologies Work together, industry, suppliers and government Learn prior to critical path Design, build, integrate, fly (annually) Federal Aviation Administration Continuous Lower Energy and Emissions and Noise FAA CLEEN 737 Platform 787 Platform Accelerating technology to improve Environmental Performance
Boeing ecoDemonstrator “uplink” efforts • On the 737 test platform, we learned: • Airlines desire applications for portable electronic devices such as graphical turbulence • Some mobile devices can work well as a Class 2 EFB, integrated with aircraft information • A suite of capabilities is enabled by a secure network file server with wireless capability: • Provides information from aircraft systems • Global, off-board broadband connectivity for near-real-time information • On the 787 test platform, we plan: • Continued maturation of charting, uplink weather/turbulence, rerouting and mitigation concepts • Efficiency gains through several mobile applications integrated with both onboard and offboard connectivity
Boeing ecoDemonstrator “downlink” efforts • On the 737 test platform, we learned: • Options for securely connected aircraft to ground by onboard networking system and off-board broadband connectivity. • Evolving architectures may host applications such as aircraft health management, flight data-recorder streaming, downlink weather / EDR and quick-access recorder data. • Operating systems that are more flexible, easier / cheaper to update. • Off-board broadband connectivity for near-real-time reporting of meteorological observations • Plans for 2013 (787-8): • Adapting EDR algorithm to 787 aircraft • Other efficiency gains through several applications integrated with both onboard and offboard connectivity • Continued prototyping of sensor integration Downlink Weather includes winds, temperatures, position, altitude, turbulence, water vapor, etc.
SummaryIntegration and flight tests are important! • Benefits: • Helps prioritize actions required to progress towards: • fuel burn reduction • on-time performance improvements • ride-quality benefits • etc. • Industry, Government, and Suppliers: • Working together to mature weather and turbulence algorithms and applications (uplink and downlink) • Demonstrate various data-link options for reduced latency and costs: POA, VDLM2, L, cellular, Ku, and Ka bands • Integration: • Help improve and integrate atmospheric sensors as well as sharing and evaluation of meteorological observations • Demonstrate aircraft network, security, and broadband data communication functions • Help improve flight test operations using new weather and turbulence applications
