SITA OptiClimb®, a digital inflight prescriptive analytics tool for fuel optimisation, has been selected by Singapore Airlines (SIA) to support the carrier’s goal of achieving net-zero carbon emissions by 2050.
By deploying SITA OptiClimb®, the airline is able to optimise fuel utilisation during the aircraft’s climb-out phase. The unique solution combines aircraft tail-specific machine-learning models with 4-D weather forecasts to recommend customised climb speeds at different altitudes. It leverages historical flight data to predict fuel burn in different flight scenarios and recommends optimised climb profiles on a user-friendly interface for pilots.
It is estimated that airlines can derive fuel savings of up to 5% during climb-out on each flight, with around 5.6 million tonnes of carbon dioxide emissions avoided annually if every airline worldwide uses SITA OptiClimb®.
Following a successful test period and validation of SITA OptiClimb® outcomes, the tool has been used on Singapore Airlines’ Airbus A350 fleet since August 2022. SITA has calculated that the solution will help the carrier cut aircraft carbon emissions by up to 15,000 tonnes annually.
