DSNA and SITA successfully trial weather intelligence for ATC

DSNA, the French air navigation services provider, have executed a successful pilot of SITA’s weather intelligence technology.

During a proof-of-concept at the Reims Area Control Centre, DSNA tested SITA’s Enhanced Weather Awareness System (eWAS) and Mission Watch over 21 days from July to October 2025. Originally developed for airlines, these SITA products provide continuous real-time updates on global weather.

During the pilot, DSNA were able to use that information to plan traffic flow significantly more effectively. The authority reported that they were able to reduce delays by up to 65% and handle 2,700 more flights, resulting in an extra €2 million in revenue.

Gael Barbezier, Head of Operations at Reims ACC, commented:

Weather is one of the biggest challenges for air navigation service providers. Working with SITA allowed us to maintain full safety, avoid any weather-related uncontrolled situations, and adjust capacity precisely to the weather avoiding unnecessary reductions in traffic. It feels like we’ve found the key to bringing stability to something that has always been unpredictable.

Unexpected disruption due to weather events can seriously derail airport operations. Earlier this year, stormy weather and poor visibility led to the closure of Nice Airport after two aircraft nearly collided on the runway. With the number of severe weather events only set to increase due to climate change, it is imperative to find better solutions for managing air traffic whatever the climate conditions.

Yann Cabaret, the CEO of SITA for Aircraft, added:

When controllers, pilots and dispatchers all see accurate, real-time weather information, they can plan and adapt together. That means fewer delays, smoother operations and safer flights for passengers.

Air India adopts SITA technology for sustainable flight ops

Air India adopts SITA technology for sustainable flight ops

Air India has adopted SITA OptiFlight’s advanced climb optimisation solution, OptiClimb, and SITA eWAS for improved operational sustainability. The data-driven insights provided will reduce the airline’s carbon emissions by 35,000 tons each year.

The Indian national carrier has adopted the software as part of is intensive modernisation strategy, which includes retrofitting its current planes and purchasing more aircraft. The SITA technology has now rolled out across its fleet of Airbus A320s and Boeing 737s, with the widebody fleet to be added soon.

The SITA OptiFlight suite helps airlines optimise key phases of flights, especially energy-intense phases. Without compromising safety or performance, the intelligence tools provide custom climb-out schedules for each aircraft, reducing fuel burn.

SITA eWAS, on the other hand, is a complementary programme that provides pilots with weather updates and predictive forecasting. The availability of this real-time data helps the crew avoid turbulence and re-route efficiently.

Sumesh Patel, President, Asia Pacific at SITA, said:

Air India’s deployment of SITA OptiFlight and eWAS is a strong example of how smart digital technologies can cut emissions, save fuel, and unlock real operational value across every flight.

Basil Kwauk, Chief Operations Officer, Air India, added:

Sustainability and efficiency are core to our transformation into a world-class airline. With SITA OptiFlight and SITA eWAS, we’re taking meaningful steps to modernize our operations, reduce our carbon footprint.

Fuel savings across the fleet as a result of SITA’s optimisations are expected to be in the region 11,000 tons. The announcement comes after Air India signed a memorandum of understanding with IndianOil for the supply of sustainable aviation fuel (SAF) in August 2025 – a further component of its net-zero emissions strategy.

Join us at Aerospace Tech Week 2026, where our dedicated Flight Ops IT and Sustainability tracks will be exploring how to improve aircraft operational performance while reducing emissions,
