Needs, benefits and vision


From rtca do 340 concept of use for meteorological and aeronautical information

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

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

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

Value of flight testing


Tim rahmes the boeing company

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 eco demonstrator uplink efforts

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 eco demonstrator downlink efforts

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.

Summary integration and flight tests are important

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
