Eco-Piloting reduces fuel use and emissions with green flying techniques
Eco-piloting is a set of fuel-efficient flying techniques that help reduce aircraft emissions by optimizing flight operations.
It is one of the most effective ways to cut carbon footprints directly, as it reduces fuel burn without requiring new technology or infrastructure.

Optimizing the Flight Route
Selecting the most efficient route helps reduce fuel consumption by avoiding unnecessary detours, strong headwinds, and turbulence. Pilots and flight planners use real-time data to make adjustments.
Optimizing Flight Speed
Flying at the ideal speed minimizes fuel burn by reducing drag and optimizing engine efficiency. Airlines calculate the best speed based on weight, altitude, and wind conditions.
Descent Planning
A continuous and optimized descent approach reduces fuel consumption by maintaining a steady, engine-idle glide with minimal thrust adjustments. This smooth descent not only conserves fuel but also lowers noise and emissions, enhancing both environmental sustainability and operational efficiency. For single-aisle aircraft like the A320 or B737, this technique can save between 30 and 70 kg of fuel per flight, while for larger aircraft, savings can exceed 250 kg per flight. [2]

Using the Engines at Idle with Thrust Reversers
During landing, thrust reversers help slow the aircraft by redirecting engine thrust forward. Using them with engines at idle reduces fuel consumption while still providing effective deceleration. This method also minimizes engine wear and lowers noise pollution, contributing to both economic and environmental benefits. ANA's implementation of Reverse Idle led to a reduction of approximately 10,608 tons of CO2 emissions per year, based on 2021 results. [3]
Eco-taxiing
Eco-taxiing combines single-engine operation, electric/conventional towing to minimize environmental impact during ground movements. By reducing reliance on engine thrust, these techniques significantly cut fuel consumption and decrease noise pollution.
Maintenance
Engine Cleaning
Flying with a clean engine improves fuel efficiency by ensuring more complete combustion. Regular engine cleaning can reduce CO₂ emissions by up to 6%, contributing to both environmental and operational benefits. [4]
Efficiency Tuning
Proactive, incremental upgrades—like optimized winglets, engine refinements, and aerodynamic enhancements—reduce fuel burn and emissions while maintaining cost-effectiveness. These precision adjustments ensure aircraft operate at peak efficiency throughout their service life.
While eco-piloting is a highly effective way to reduce fuel consumption and emissions, it is not always applicable in every situation. Safety remains the top priority, and operational factors such as air traffic control, weather conditions, and airport procedures can sometimes prevent its use. Additionally, there are no strict regulations enforcing eco-piloting—its implementation is left to the pilot’s discretion, guided only by airline recommendations. Furthermore, local civil aviation authorities and airports play a crucial role in enabling these techniques, but current regulations and infrastructure do not always support their widespread application. As a result, even when pilots are willing to apply eco-piloting, external constraints may limit their ability to do so.
