3. The best service at the best price

euro € 67.55

unit rate charged by skeyes for an en-route service unit in the airspace for which it is responsible

euro -12%

underlying the Unit rate charged, there is the DUC (Determined Unit Cost set by the European Commission) which is €57.37 (in 2009 real terms), or a reduction of 2.3% compared to 2018 and a reduction of 12% compared to the starting base of €65.90 in 2014. skeyes has recorded the best performance in FABEC in terms of application of the agreed reduction in costs.

For en-route traffic, the fees are in proportion to the distance travelled and the square root of an aircraft’s mass. A service unit corresponds to the control of an aircraft of 50 tonnes over 100 kilometres.
