Network Operations Report - April 2015

19 May 2015

Traffic in April 2015 increased by 1.7% compared to April 2014 and was above the high forecast. French ATC industrial action between 8 and 10 April resulted in the removal of approximately 3,400 flights* from the network. Traffic avoiding the Ukraine airspace and other areas (Syria, Libya) continues to distort traditional traffic flows with some ACCs experiencing either high growth, or reductions, in traffic. Traffic to Egypt increased by 17% generating additional demand for Athens, Nicosia and Makedonia ACCs.

En-route ATFM delays increased by 117% compared to April 2014 and airport ATFM delays increased by 74%. En-route ATC disruption delays (strikes) accounted for 34% of ATFM delays in April.

Highlights include:

  • The French ATC industrial action between 8 and 10 April 2015 generated 391,000 min of ATFM delay in the French ACCs; Maastricht, Karlsruhe and Madrid ACCs generated 51,715 min due to ATFM protective measures.
  • Nicosia ACC had high traffic growth and high ATFM delays with a significant increase in the average delay per flight.
  • Istanbul/Ataturk and Istanbul/Sabiha Gökcen airports continue to generate airport capacity delays.
  • Amsterdam Schiphol airport generated delays due to weather and the VCS system implementation.
  • Military activity in Maastricht and Nicosia airspace generated over 20,000 min of delay.

The average en-route delay per flight in April 2015 was 0.93 min/flt, which is above the monthly guideline* value of 0.35 min/flt. The average YTD enroute ATFM delay per flight in 2015 in the NM area is 0.38 min/flt, which is above the corresponding guideline value of 0.27 min/flt.

* NM Estimation

** NM’s calculation that provides the guideline en-route delay (min) requirements to achieve the annual target (0.5 min/flight).
