Overall, in 2016 tactical directs resulted in an average reduction of 15 kilometres in the distance flown per flight when compared with the routing originally planned, with the average distance flown declining from 528 kilometres to 513 kilometres per flight. The benefit for airspace users can be expressed in the reduction of fuel burned of 278,000 tons, or in monetary terms EUR 352 million. Beside this, air traffic controllers reduced the environmental footprint of aviation by 938,000 tons of CO2.
