A new interim Departures Code of Practice has been unveiled which aims at helping cut aircraft emissions by reducing fuel burn from aircraft at airports.
The interim voluntary code of practice has been compiled 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 that represent aircraft manufacturers.
The code states that shutting down an engine during taxi-in operations should be planned in advance and implemented early in order to obtain maximum environmental benefits and to reduce fuel burn.
According to the document, standard operating procedures should be reviewed by aircraft operators to help promote taxiing with fewer engines running while an aircraft is proceeding towards the terminal from the runway.
Reductions of 20% to 40% of the ground level fuel burn and CO2 emissions, and 10% to 30% of ground-emitted oxides of nitrogen emissions can be achieved when an engine is shut down during taxi-in operations, the code notes.
