2. NASA Aviation Weather Safety
Objective:
Improve pilots’ ability to obtain, understand and use weather information for safer decision-making
Challenges:
Improve access/dissemination of weather information
Improve user interface
Fully utilize on-board and data-linked weather sources
Improve weather situational awareness and decision-making
Research Thrusts:
Weather Situational Awareness
Weather Decision Aiding
Weather Dissemination
<<Information not data>>

3. Situational Awareness
Progress to-date:
Completed special populations study
Completed CoWS & WARP experiments
Completed data collection for METAR depiction experiment
Conducted 4 piloted simulation experiments with RTI & CAMI
Completed 3 deployments for CoRRaL using NASA King Air
Future Plans:
Investigate trending of weather information (numerous tasks)
NEXRAD looping (historical to current observation)
Incorporate forecasting (NCWF)
Assess COTS flight planning software capabilities for cockpit applicability
Analyze judgment & piloting performance from CoWS & WARP
Contract to study pilots’ use of GA AWIN systems
Study image analysis techniques for detection of IMC
Investigate presentation concepts for TAMDAR

4. Decision Aiding Progress to-date: Future Plans:
Implemented Aviation Hazard Awareness System (AHAS) in-flight weather analysis tool on NASA B-757 for FY03 piloted evaluation experiment
Considers weather information along with mission & equipment profile
Integrates on-board and data-linked weather information
Future Plans:
Conduct RTI simulator experiment on automatic decision-aiding
Perform flight evaluation of AHAS with commercial pilots
Integrate turbulence hazard display into AHAS and perform simulator experiment
Assess via integrated flight deck experiment:
AHAS display
Radar display
Aural Alerting

5. Dissemination Progress to-date: Future Plans:
Defined datalink architectures satisfying comm requirements
Performed modeling & simulations to validate target architecture
Performed initial experimental assessments of datalinks
Selected target links for architecture validation:
Domestic Air Transport: 1090ES, FISDL, VDL Mode 2
GA and Regionals: UAT
International Ops: Inmarsat Swift64
Future Plans:
Perform 1090ES, FISDL, UAT and VDLM2 technical modifications to support
Perform laboratory and flight validation of individual datalinks
Perform integrated flight validation with other technologies
Displays (AHAS, turbulence display..)
Weather products
Sensors (turbulence radar, TAMDAR)
