Weather Technology in the Cockpit (WTIC)
• A portfolio of related research and development (R&D) activities to
ensure the adoption of cockpit, ground, and communication
technologies, practices, and procedures that will:
– Provide pilots with shared and consistent weather information to
enhance common situational awareness
– Provide airborne tools to exploit the common weather picture
– Utilize the “aircraft as a node” functions to autonomously exchange
weather information with surrounding aircraft and ground systems
– Facilitate integration of weather information into cockpit NextGen
capabilities (e.g. Trajectory Based Operations)

weather sensor and model data to generate a suite of convective weather forecast (0 – 2 Hr) products for the northeast corridor.
• CIWS does not incorporate airborne sensor data
• Integration of CIWS products with Traffic Flow Management Decision Support Tools
• CIWS functionality will be component in NextGen Weather Processor
– CIWS products are currently disseminated to 15 FAA facilities (ATCSCC, ARTCCs, TRACONs), airlines operations centers, and several R&D organizations.
– CIWS was developed, operated and maintained by MIT Lincoln Laboratory

ITWS-How does it fit into the NAS?
• ITWS is integrated into the FAA’s Strategic Management Plan
• ITWS helps fill the performance gap identified in the FAA’s Greater Capacity goal:– Objective 1: Increase airport capacity to meet projected demand– Strategy 1: Improve technologies to make air traffic flow more
efficiently during periods of adverse weather
• ITWS provides significant economic benefits in airline operations efficiencies and passenger time savings– Estimated benefits to cost ratios as high as 19.8:1
