Weather Awareness Service for your Electronic Flight Bag eWAS provides airline pilots a complete weather situation for their flights. The application presents the last observations and forecasts in an innovative horizontal and vertical view providing a clear 4D view with the time. eWAS data can be used at ground for a better flight preparation and even onboard the aircraft to receive continuous updates during the flight. Thanks to specific integration onboard the aircraft, data can be received by satellite and even by ACARS communication. New data format and compression allow eWAS to uplink forecast with a very limited bandwidth to limit the communication costs. ATC flight plan can be directly requested to the eWAS ground servers or copy paste from the flight folder. eWAS offers the following weather data: · Thunderstorm forecast and nowcast · Clear air turbulence · Icing · Volcanic Ash · Lightning · SIGMET · Pireps · Wind · Tropopause · METAR / TAF · And more data on request. Highly customizable, the application allows to define an airline policy with various options including the selections of various weather providers. Specific connection to the Airline OCC can also be requested to get for example flight plans and airports. ## Key features - 4D weather visualization - Thunderstorm forecast & nowcast - Clear air turbulence & icing - Volcanic ash & lightning data - SIGMET, Pireps, Wind, Tropopause - METAR/TAF reports - Satellite & ACARS data reception ## Recent user reviews (10 of 39) All indexed reviews: https://appshunter.io/ios/app/sita-ewas/id1005569119/reviews.md ### 4/5 — Crash when zooming in and out using Magic Keyboard trackpad *2025-03-19, version 3.8.0* Great app but some bugs when used with Magic Keyboard ### 1/5 — SITA killed eWAS *2024-09-24, version 3.7.3* Since takeover by SITA, eWAS is slowly decaying, becoming a 2nd zone app, with no major improvements and no bug correction. -GPS position: we still get this stupid enormous circle instead of a ship symbol « because it shouldn’t be used for navigation purpose », as if we are going to navigate with eWAS. Silly. -Preferences: eWAS can’t keep my preference settings from one flight to another. And there’s even more dumb: for a Paris-Roma flight for instance, eWAS insists on showing me Pacific and Atlantic Tracks, but in the same time is removes the company’s adequat airfields. How convenient! -Devices management made more complicated than before. No chance to add/remove a device directly on the associated website. You have to do it on the app. And not to mention the lack of innovation, like a meteogram for a particular position, of other filters like risks of low visibility, or thunderstorms. I have to revert to the good old mix of informations between several sources to have a better idea of a weather, which was the aim fo eWAS in the first place: combining several sources into one app for a better understanding and visibility. Too bad SITA is only here to take advantage of the profits generated by eWAS without making any investment on it. ### 2/5 — Ça se dégrade *2024-05-30, version 3.7.1* Du jour au lendemain accès professionnel planté et l’accès à mes « devices « autorisés ne me,permet plus de les gérer moi même.
