The new Departures Code of Practice promotes how aircraft can taxi to and from the runway with less than all engines operating, leading to significant reductions in ground noise, CO2 and NOx emissions, depending on aircraft type and operator techniques.
Welcoming the publication of the new guidance, Dr Andy Jefferson, Stansted Airport’s head of environment, said:
“It's really great news that a new interim departures code of practice has been agreed. I'm particularly delighted as we have helped lead the trialling of this new technique here at Stansted, working very closely with easyJet, so it's very pleasing to see all our hard work coming to fruition.
“We have already enjoyed significant success with a similar collaborative approach when we developed and subsequently updated the arrivals code of practice, which has led to the introduction of continuous descent approaches at Stansted. I believe this next step will help build on that excellent work, maintain our forward momentum and is further evidence of our commitment to explore new and innovative ways to address the industry's environmental impacts.
“I also believe the collaborative approach the aviation industry has adopted is the best and most practical way forward. Working together as an industry, we are all able to fully focus on the wide range of issues and challenges the sector faces as we look to satisfy future passenger demand for air travel while at the same time achieving our aim to reduce aircraft noise impacts and meet aviation's commitment is to reduce CO2 emissions from aircraft by 50% by 2050 compared to 2005 levels.
“To this end, and to fully utilise the experience and knowledge of all the local participants in the coalition, we’ve now established the Stansted Aircraft Emissions Working Group which has been tasked to determine how the Stansted airlines might best use the recommendations made in this code of practice.”
The Code has been produced by a group representing airlines, airports, air traffic control, the Civil Aviation Authority (CAA) and ADS – the UK’s aerospace, defence and security trade body.
George Hutton, easyjet’s pilot manager at Stansted, said:
"easyJet has invested billions in the latest technology to make sure that we operate one of the cleanest, youngest and most fuel efficient fleets in the industry - the average age of our aircraft is just 3.4 years.
"We’ve been working in collaboration with Stansted Airport’s environment team for three years to explore noise and emissions saving strategies. As a result of this work, single-engine taxiing is now part of easyJet’s Standard Operating Procedures almost everywhere we fly to. Airlines adopting this procedure could see reductions in ground emissions of up to 30% and a taxi fuel saving of up to 40% depending on aircraft type and operator techniques."
