means a volume of airspace that extends from the ground up to, and including, upper airspace, where en route air navigation services are provided and for which a single cost base and a single unit rate are established;
- en route horizontal flight efficiency reference value
means the estimated value by the Network Manager of the flight efficiency of the actual trajectory at national level or at the level of functional airspace blocks, for the purpose of ensuring that the Union-wide target on horizontal en route flight efficiency of the actual trajectory is met.
- en route part
refers to the distance flown outside a circle of 40NM around the origin and destination airports;
- estimated take-off time
means the forecast of time when the aircraft will become airborne calculated by the Network Manager and based on the last estimated off-block time, or target off-block time for those airports covered by airport collaborative decision-making procedures, plus the estimated taxi-out time calculated by the Network Manager;
- estimated taxi-out time
means the estimated time between off-block and take-off.
- exceptional event
means circumstances under which ATM capacity is abnormally reduced so that the level of air traffic flow management (‘ATFM’) delays is abnormally high, as a result of a planned limitation induced through operational or technical change, major adverse weather circumstances, the unavailability of large airspace parts either through natural or political reasons, or industrial action, and the activation of the European Aviation Crisis Coordination Cell (‘EACCC’) by the Network Manager;
- forecast inflation index
means the annual inflation index based on the third year before the start of a reference period and computed by using the latest available inflation forecast of average Consumer Price Index percentage change published by the International Monetary Fund for the Member State concerned at the time of drafting the performance plan.

- reference value
means the value computed by the Network Manager of en route ATFM delay for each Member State and each functional airspace block for the purpose of ensuring that the Union-wide en route ATFM delay target is met;
- restructuring costs
means significant one-time costs incurred by air navigation service providers in the process of restructuring for introducing new technologies, procedures or business models to stimulate integrated service provision, compensating employees, closing air traffic control centres, shifting activities to new locations, writing off assets or acquiring strategic participations in other air navigation service providers;
- runway incursion
means any occurrence at an aerodrome involving the incorrect presence of an aircraft, vehicle or person on the protected area of a surface designated for the landing and take-off of aircraft;
- separation minima infringement
means a situation in which prescribed separation minima were not maintained between aircraft;
- terminal charging zone
means an airport or a group of airports, located within the territories of a Member State, where terminal air navigation services are provided and for which a single cost base and a single unit rate are established.
