SITA Unveils eWAS+, an Advanced EFB Solution Combining Real-Time Weather and Operational Flight Data. Aviation IT provider SITA has launched eWAS+, a next-generation Electronic Flight Bag (EFB) application developed to merge weather forecasting and operational parameters into a single pilot interface. The software consolidates situational metrics historically spread across disconnected platforms, enhancing cockpit workflow and situational awareness across all operational phases of flight.

Building on the legacy of the original SITA eWAS platform—leveraged over the past 12 years by more than 40,000 flight crew members across 60-plus commercial airlines—the enhanced tool focuses on the early detection of Clear Air Turbulence (CAT), a hazard invisible to standard onboard weather radar systems. Access to this predictive data allows flight crews to proactively adjust cruising altitudes and flight paths before encountering unstable air masses.
The system aggregates data feeds from over 10 certified meteorological providers and more than 40 specialized atmospheric models, delivering actionable forecasts on headwinds, jet streams, structural icing, convective storms, and turbulence, overlaid against airspace limits, airways, and airport waypoints. An integrated four-dimensional (4D) display engine maps how weather patterns will change relative to the aircraft’s projected arrival times along each waypoint.

Furthermore, eWAS+ integrates with SITA OptiFlight, an analytics suite designed to optimize climb, cruise, and descent profiles to lower fuel burn and cut operational carbon footprints. Albert Dominguez, Head of Aviation Data and Applications at SITA for Aircraft, noted that the platform was engineered directly around pilot and airline user input, providing parity across iPadOS and Windows platforms via commercial App Store distribution and enterprise deployment channels.
