Experts from air navigation service providers (ANSP) of the Functional Airspace Block Europe Central (FABEC) have suggested vertical flight efficiency (VFE) improvements for the European airspace.
The experts investigated on enhanced adapting capabilities of vertical restrictions to seasonal and time-based procedures, reported Air Traffic Management.
As a result, 30 city pairs have been improved to allow aircraft to enjoy better vertical flight efficiency.
Based on the city pairs, which are the fixed routes between major airports, aircraft can travel either through a defined higher flight level or the flight level requested.
Implementations of improved city pairs have been continuing in phases since 2015.
These improvements in flight routes help increase fuel efficiency, while reducing carbon dioxide (CO2) emissions.
The six FABEC states of Europe, including France, Germany, the Netherlands, Belgium, Luxembourg and Switzerland, have one of the busiest and most complex airspace worldwide.
FABEC airspace, which handles 55% of air traffic of Europe, spans an area of 1.7 million km². The area covering this airspace is occupied by major European airports, military training areas and civil airways.
Nearly 5.5 million flights travel across the airspace every year.
The seven civil air navigation service providers of FABEC include ANA in Luxembourg, DFS in Germany, LVNL in Netherlands, Belgocontrol in Belgium, DSNA in France, MUAC in Eurocontrol and skyguide in Switzerland.
