We have helped in a number of research initiatives to measure the NOx output from our aircraft engines and auxillary power units (APU's).
We have also helped with novel research methods aiming to help understand what happens to these emissions after they leave the aircraft.
In conjunction with Qinetiq, British Airways has also carried out research into particle emissions from tyres and brakes, to aid understanding of the environmental impact this may have. This work started in 2005 - the latest development was in October 2008 when we obtained samples of tyre and brake dust from a number of aircraft. This material has been passed to Oxford University and Manchester Metropolitan University for the development of measurement equipment to gain a better understanding of the characteristics of the dust that ends up attached to the wheels and aircraft.
