  • Purpose
  • Justification
  • Synopsis of Vision
  • Operational Concept of Use
  • Benefits
  • Implementation Issues
  • AVS Weather Related Documents
  • Summary
  • Define a Near-term Concept of Operational Use For Weather in The Cockpit
  • Establish a Common Understanding of Weather in The Cockpit
  • Provides a Foundation For Collaboration With Others in Industry, Government, Academia
  • Today’s Presentation is Intended To Start a Dialogue With Other Stakeholders
  • Needs exists for common situational awareness between
    • Pilot
    • Controller
    • Dispatcher (Flight Service Station specialists in GA)
  • Leads to enhanced decision making and shared responsibility in making decisions related to weather
shared responsibility
Shared Responsibility
  • Flight Service Stations
  • Airline Dispatch
  • Air Traffic Control
  • Pilots and Aircrews
  • Safety - Prevent Weather Accidents and Fatalities
    • Weather largest cause of GA fatalities in the U.S, 200 deaths annually
    • Weather is causal factor more than twice as often as any other factor in GA fatal accidents
  • Safety – Mitigate cabin injuries due to turbulence
  • Efficiency – Aid in Selecting Most Cost-Effective Routes
synopsis of weather in the cockpit vision
Synopsis of Weather-in-the-Cockpit Vision

“Enable flight deck weather information technologies that allow pilots and aircrews to engage in shared situational awareness and shared responsibilities with controllers, dispatchers, Flight Service Station specialists, and others, pertaining to preflight, en route, and post flight aviation safety decisions involving weather.”

operational concept of use
Operational Concept of Use
  • Cockpit-oriented Operational Concept Of Use
  • Focuses On Certification Design Requirements, Flight Technical Standards, Training, and Procedures, and Weather Information
  • Tied Together By a Network-centric Enabled Operation Such As SWIM

implementation issues
Implementation Issues
  • Use of Airborne Data Sensors
  • Development of Weather Products
  • Training and Human Factors Considerations
  • Integration of Weather Data from Multiple Sources
  • Determine What Weather Information is Needed By Each Group of Decision Makers
airborne sensors and comm links
Airborne Sensors and Comm Links
  • Airborne Turbulence Detection System
  • TAMDAR - Tropospheric Airborne Meteorological Data Reporting
  • MDCRS - Meteorological Data Collection and Reporting System
  • TAPS – Turbulence AutoPIREP System
  • Systems use both airborne sensors (cross link) and data link
weather data link product development evolution
Weather Data Link Product Development & Evolution
  • Text to Graphics (Today’s “First generation”)
  • Weather Trending and Probabilistic Products
  • Fully Integrated Electronic Moving Map, Weather, Terrain, Obstacles, and Traffic Displays
  • Depictions Present Both Permanent and Temporary Change Data To Crews in an Intuitive, Easy To Comprehend Manner
data link design considerations
Data Link Design Considerations
  • Equipment and Displays with appropriate Data Link Communication Protocols
  • Weather Products
  • Appropriate Standards, Evaluation and Certification
  • Archiving Onboard Data For Post-flight Retrieval and Analysis
strategic tactical and controlling
Strategic, Tactical, and Controlling
  • Strategic
    • CBs over Iowa and Nebraska, moving NE at 20 knots, tops to FL 450.
  • Tactical
    • IMC in 5 NM; a 180 degree turn will place aircraft in VMC
  • Controlling
    • Altimeter two niner seven niner (29.79)
    • RVR… Trending data for last 10 minutes shows a RVR of 400 meters, Runway 12R.
training and human factors considerations
Training and Human Factors Considerations
  • Important to ensure proper use of tools and that tools are human-centered principles
  • Design training on crew resource and risk management and aeronautical and pilot decision-making
  • Design software and hardware based upon common human factor functional design standards to facilitate ease of training and use
