LATAM Airlines Group has rolled out the Aircraft Performance Monitoring (APM) software across its entire fleet. Developed by European company Storkjet, the solution is part of LATAM’s ongoing efforts to improve operational efficiency and reduce fuel consumption.
The software allows LATAM to compare each aircraft’s real-time flight performance against its original factory specifications, enabling flight planning and execution to reflect the aircraft’s current condition. This is critical because aircraft lose efficiency over time. While the aircraft’s onboard systems calculate performance based on ideal factory conditions, APM enables more precise adjustments—both in planning and in flight—so decisions and estimates are based on real-world performance, reducing fuel burn and related emissions. In simple terms, the aircraft flies more precisely and efficiently based on its actual condition, not as if it were brand new.
A key feature of the system is the ability to monitor the real performance of each aircraft, which allows LATAM to quantify with high accuracy how much more fuel is being used compared to when the aircraft was new. This performance tracking also enables targeted maintenance actions that boost efficiency, such as engine or fuselage cleaning, or control surface realignments.
Another feature with a significant efficiency impact is the Idle Factor, specific to the Airbus fleet. It optimises the point at which the aircraft should begin its descent. By comparing current engine thrust to original performance data, the software adjusts the aircraft’s onboard calculations to ensure descent is carried out with minimal drag and engine use—leading to a smoother, more fuel-efficient descent.
The implementation of this system is expected to save LATAM around US$2.5 million in fuel annually and avoid nearly 7,900 tonnes of CO₂ emissions. In addition, it provides new data to identify further opportunities for efficiency.
“We know that sustainability is built through daily operations and concrete actions,” says Stephano Gachet, Head of Fuel and Procurement 
at LATAM Airlines Group and leader of the Fuel Efficiency programme. “The integration of this software shows how technology and innovation can help us become more efficient on every flight—optimising resources and reducing greenhouse gas emissions. Tools like these are key to continuing our responsible journey toward more sustainable aviation.”
This initiative strengthens LATAM’s Fuel Efficiency programme, launched in 2010, which has improved the group’s operational efficiency by 6.5%. It has helped avoid the consumption of over 2 million barrels of jet fuel per year and more than 5.6 million tonnes of CO₂ emissions—equivalent to LATAM’s total annual emissions from its operations in Ecuador, Colombia, and Chile combined, or nearly half of the group’s total Scope 1 emissions for the same period.
