Airline opportunities

eWAS provides a rich, graphical, intuitive display of turbulence, lightning and high altitude ice crystals, allowing flight crew to make the safest and most efficient enroute tactical decisions. Offering pilots a real-time, graphically optimized view of weather sources with both forecasts and current information covering both the horizontal and vertical planes allows for a more economical, intelligent and flexible journey plan.

According to a recent study, the risk of transatlantic flights encountering significant turbulence will increase by 40% – 170% by 2050.

Airlines face a number of practical challenges when offering graphical weather application to pilots; an airline can hold a diverse fleet with different EFB hardware, connectivity, OS and software environments. There is currently a lack of pilot-centric weather applications in the cockpit, and existing, limited weather information is only available on the ground for flight-planning purposes.

eWAS can address these challenges.

Product description

SITAONAIR has developed eWAS to be totally ubiquitous. It is therefore simple for airlines to equip their entire fleet, despite mixed connectivity and aircraft types.

Data is transmitted using highly efficient compression, allowing eWAS to be easily updated over Wi-Fi, 3G or 4G on the ground and via either a cabin or cockpit broadband link in the air.

eWAS is compatible with any EFB hardware, OS or core EFB software, including both Apple and Windows devices, as well as the major avionics systems.

Features and benefits

Multi-source weather information

Provide pilots with accurate, real-time weather reports focused on key dynamic situations, including turbulence and thunderstorms. Through multi-sourced weather information, pilots can be better prepared for the flight and offer your customers the most efficient and comfortable service whilst protecting On Time Performance and minimizing unnecessary fuel burn.

Fully integrated with the airline environment

Flight details (times, speeds, flight profile) are fed from customer flight planning providers – delivering a seamless and consistent experience for the eWAS end-user. Cockpit integration is achieved through interfacing with ARINC 429 data, via an airline AID device or dedicated aircraft IP connections.

Real-time graphical view of the best-in-class forecasts and current information

Provide pilots with the most up-to-date weather forecasts, with both vertical and horizontal profiles straight to their tablets, phones and on-board devices before departure and, in the case of connected aircraft, during a flight.
