Thales’ FlytOptim selected by Corsair to cut CO₂ emissions and advance sustainable aviation
  • Airline company Corsair has selected Thales’ flight optimization solution, FlytOptim, across all of its flights, which serve Africa, the West Indies, and the Indian Ocean (5000+ per year), to save thousands of tonnes of CO2 emissions per year.
  • Following trials, this solution has saved several hundred kilograms of fuel on each flight and helped avoid more than 300 tonnes of CO2 on Corsair flight routes to the West Indies and Africa.
  • With this solution, Thales, a key player in sustainable aviation, offers a systematic approach that can be quickly integrated by all airlines, seeking to reduce their environmental impact as of today.

FlytOptim is an intuitive AI-powered solution that enables pilots to optimize their vertical flight trajectory using real-time weather and aircraft data, thus enabling them to reduce their fuel consumption by 2%.

Harnessing AI to reduce emissions and advance sustainable aviation

This innovation uses Thales’ trusted AI and advanced prediction algorithms of its Flight Management System (FMS), PureFlyt, to identify the optimal vertical flight path, based on real-time weather and aircraft data (such as mass and position). When an optimization is possible, the alternative vertical flight path is sent directly to the pilot in the cockpit using existing communication channels. Once approved by air traffic control (ATC), the pilot can update the flight plan accordingly.

User-centric experience with no operational disruption

Designed together with pilots, FlytOptim’s intuitive design and efficient user-experience has seen an unparalleled adoption rate: after only a few weeks trial at Corsair, 80% of the flights were using FlytOptim. FlytOptim can be deployed quickly and easily, with no need to modify the aircraft or the airline’s existing IT systems.

A comprehensive range of more environmentally-friendly solutions

This solution marks another step in Thales’ roadmap towards climate-efficient aviation, offering both CO2 and non-CO2 reduction tools for pilots, dispatchers, air traffic controllers and flow managers. FlytOptim will progressively integrate Thales’ other green operations innovations including its contrail avoidance solution and the dynamic management of Air Traffic Control constraints, thus supporting aviation industry customers in their journey towards more efficient operations.
