TUI implements SITA’s machine-learning flight tech
TUI Airline has implemented the SITA OptiClimb solution across all five of its airlines.
This is part of the group’s sustainability mission to reduce airline emissions.
It initially used SITA’s tech on a partial deployment, successfully saving up to 200 kg of fuel and 600 kg of CO2 per aircraft per day.
SITA OptiClimb is a predictive analytics solution that uses machine learning to build tail-specific performance models.
It is fed with 4D weather forecasts and operational flight plan inputs.
This data is used to predict fuel burn scenarios.
It provides pilots with customised climb speeds and acceleration levels specific to each tail and flight, and so they can optimise fuel without compromising flight times.
According to the International Air Transport Association (IATA), fuel represents almost 30% of an airline’s operating costs.
Airlines are adopting digital applications such as SITA OptiClimb for fuel and emission reductions alongside longer-term strategies like sustainable aviation fuels.
SITA estimates saving about 5.6 million tons of carbon annually if every airline used SITA OptiClimb.
The tech is now fully deployed across all five airlines in the TUI Group.
These are TUI Airways, TUI fly Belgium, TUI fly Germany, TUI fly Netherlands, and TUI fly Nordic.
It delivered total savings for TUI Airline of around 4,500 tons of fuel and 14,000 tons of carbon in 2022.
