Heathrow Airport is embarking on a new journey to prioritize environmental performance, thanks to innovative technology developed by NATS, the air traffic service provider. This significant step marks a shift in airport operations, aiming not just for punctuality but also for sustainability.
Introducing the Demand Capacity Balancer
The Demand Capacity Balancer (DCB), a sophisticated ‘digital twin,’ has been in operation at Heathrow since 2015. This technology enables the airport to predict and model future operational performance almost in real-time. It accounts for various factors such as global wind strength and airspace restrictions, helping Heathrow manage its daily operations with precision.
From Punctuality to Sustainability
Initially, DCB was utilized to enhance punctuality, saving an impressive 47,000 minutes of delay annually, which translates to a financial saving of £4.1 million*. Now, the same analytical prowess is being redirected towards reducing emissions. This shift underscores Heathrow’s commitment to becoming more environmentally responsible.
How DCB Enhances Environmental Performance
NATS is introducing a suite of new features for DCB, focusing on environmental performance. These features will allow Heathrow to measure the efficiency of arriving aircraft and identify the optimal daily operating plan to minimize CO2 emissions.
Starting in 2025, NATS plans to trial a new functionality that involves adjusting aircraft speeds while they are still hundreds or thousands of miles away from the airport. This small adjustment, though minor for individual flights, can cumulatively lead to a significant reduction in emissions, potentially saving up to 30,000 tonnes of CO2 annually**.
Benefits Beyond the Environment
The environmental benefits of this initiative extend beyond reducing emissions. Airlines, passengers, and local residents will all experience positive impacts through reduced airborne holding times and lower overall fuel consumption on approaches into London. This initiative aligns perfectly with Heathrow’s updated business strategy, which emphasizes both people and planet, setting a clear path towards achieving net zero emissions by 2050.
Voices from Heathrow and NATS
Kelly Stone, Head of Airport Operations at Heathrow, expressed her enthusiasm for the new environmental focus of DCB. « It is fantastic to see the Demand Capacity Balancer’s use extended to environmental performance. Small incremental steps like this are vital to reduce ‘in the air’ emissions to reach Heathrow’s goal of net zero by 2050. I am grateful for NATS’ ongoing commitment in bringing world-first technology to Heathrow, helping us be an extraordinary airport, fit for the future. »
Guy Adams, Managing Director of NATS Services, highlighted the success of DCB at Heathrow. « Demand Capacity Balancer is a proven success at Heathrow, helping save several millions of pounds a year by reducing delay, so it makes perfect sense to harness that same analytical technology to include environmental performance. No other airport in the world has this capability, and NATS is proud to be supporting Heathrow’s ambition. »
The Power of Digital Twin Technology
As a digital twin, DCB can simulate future airport performance and the impact of any changes to the flight schedule almost instantaneously. This capability was crucial during the management of airspace restrictions for the Queen’s funeral, allowing 85% of the normal schedule to run on time.
Looking Ahead
The new suite of environmental tools for DCB, developed jointly by NATS and Frequentis, is set to go live at Heathrow in November. This launch marks a significant milestone in Heathrow’s journey towards sustainability, showcasing the airport’s dedication to integrating cutting-edge technology to meet its environmental goals.
Heathrow’s New Environmental Initiative: A Step Towards a Greener Future
Heathrow’s adoption of NATS’ Demand Capacity Balancer for environmental performance is a promising step towards a greener future. This initiative not only aims to reduce CO2 emissions significantly but also sets a precedent for other airports worldwide. As Heathrow continues to innovate and prioritize sustainability, it paves the way for a future where air travel can be both efficient and environmentally friendly.
