A UK aviation coalition including airport operators BAA, airlines BA and Virgin Atlantic and the CAA have published a new interim code of practice this week, designed to help cut aircraft emissions by reducing fuel burn from aircraft at airports. The document is technical in nature, and so primarily targeted at pilots, flight planners and airport operators who are collectively encouraged to get involved in methods such as single-engine taxiing, once safety considerations are assured. By shutting down an engine during taxi-in operations pilots are told they could achieve reductions of 20-40% of the ground level fuel burn and CO2 emissions, and 10-30% of ground NOx emissions, depending on aircraft type and operator technique.

The environmental practices that are highlighted in the document are also said to deliver significant improvements to noise and local air quality at airports and reduce costs to airlines. Thus as well as providing global environmental benefits, it delivers additional local benefits to people living and working around airports.

The voluntary set of guidelines has been published ahead of the full version of the code that is expected to be finalised early next year, which will include advice on the use of airport terminal and ground power rather than running the aircraft’s auxiliary power unit, ‘continuous climb departures’, and collaborative decision making to deliver further improvements.
