Aviation sustainability developments from around the world

The Tui Airline Group has fully implemented the SITA OptiClimb^® solution across all five of its airlines as part of the group’s sustainability agenda to reduce airline emissions. The wider deployment of SITA’s technology follows the success of its partial deployment, saving up to 200 kg of fuel and 600 kg of CO₂ per aircraft per day. Aircraft climb is the most fuel-intensive phase of a flight. SITA OptiClimb^® is an innovative predictive analytics solution that uses machine learning to build tail-specific performance models. Fed with 4D weather forecasts and operational flight plan inputs, these models predict fuel burn scenarios. The solution then provides pilots with customized climb speeds and acceleration levels specific to each tail and flight to optimize fuel without compromising flight times. 

Mid-November Rolls-Royce announced that it has successfully completed compatibility testing of 100% Sustainable Aviation Fuel (SAF) on all its in-production civil aero engine types. This fulfils a commitment, made in 2021, to demonstrate there are no engine technology barriers to the use of 100% SAF. Testing has involved a variety of ground and flight tests to replicate in-service conditions. All the tests confirmed the use of 100% SAF does not affect engine performance.
