Strikes in April are estimated to have caused around 525 flight cancellations. This graph shows the variation in total traffic for the last 12- month period relative to that for the 12-month period before. The total traffic from May 211 to April 212 increased by.2% relative to that from May 21 to April 211. Note that the observed decrease between March and April is due in part to the effects of the April 21 ash cloud being no longer in the reference period (May 21 to April 211). There is a general deceleration in the traffic growth since December 211. DNM Network Operations Report Analysis - April 212 1
In April 212, several main airports experienced a decrease in traffic (e.g. Paris CDG, Frankfurt, London Heathrow, Amsterdam, Munich, Madrid, Rome Fiumicino and Barcelona) compared to 211. The largest decrease was at Madrid (Spanair cessation of operations and reduced Iberia traffic). Ferihegy Budapest recorded a 23.6% decrease as Malév Hungarian Airlines ceased operations. The largest increase in traffic was at Istanbul Ataturk (12.2%). For air operators, the most significant decreases were for Czech Airlines (-34.3%), Cimber Air A/S (-24.8%), Iberia (-22.9% and Regional Airline (-21.4%). The largest growth was for United Airlines (114.3%) and Naysa (44.6%),these changes were due to airline consolidation and restructuring rather than traffic growth. With the exception of Lufthansa, the traffic for the top 8 carriers (Ryanair, Easyjet,Turkish Airlines, SAS, Air France, British Airways and KLM) increased in April 212. Unidentified operators (mainly General Aviation) recorded a decrease of 8.6% in April 212. DNM Network Operations Report Analysis - April 212 2
Yerevan, Stavanger, Tallinn, Ankara, Istanbul and Warsaw ACCs experienced a significant increase in traffic. Malta recorded an increase of 17% compared to April 211; this increase is traffic recovery from last years Libyan airspace closure. Spain (Madrid, Seville, Barcelona and Palma ACCs), Makedonia, Tampere, Tirana, Belgrade and Skopje ACCs recorded significant decreases in traffic. DNM Network Operations Report Analysis - April 212 3

Figures are the average daily delays in minutes. Pink dashes (Year- To-Date - YTD) indicate their average daily ATFM delay since the beginning of the year. Marseille, Bordeaux and Brest ACCs experienced the highest delays and exceeded their year to date situation mainly due to the French industrial action that took place between the 2 nd and the 4 th April. London Heathrow recorded significant weather delays due to strong winds. Nicosia, Barcelona, Lisbon, Paris and Madrid ACCs generated ATC capacity delays. Langen ACC continues to record significant ATC capacity and staffing delays; however a significant improvement can be noted since March 212. Istanbul registered delays due to ongoing airport infrastructure, cross wind, heavy rain and increase in traffic. Paris Orly and Paris CDG airports also registered delays linked to weather (thunderstorms, strong wind) and the French industrial action. Zurich airport was affected by ATC capacity delays, strong wind and runway configuration. The military exercise FRISIAN FLAG affected significantly Maastricht UAC generating delays mainly in JEV, DELHI and JEHI sectors. Delays in Ankara ACC were due to reduced ATC Capacity in ORBB (Baghdad) FIR (NOTAM A4/12).

Consequently, the year-to-date en-route delay per flight result (.48 min/flt) is now higher than the optimum* year-to-date target (.38 min/flt) at this stage of the year. Those results are directly linked to French industrial action. Since the beginning of the year, an average of 269 flights per day was subject to an en-route delay of more than 15 minutes which is below the 211 level. * NM s calculation that provides the optimum en-route delay (min) requirements to achieve the end-of-years target (.7 min/flight).

Most significant delays were recorded: On Monday the 2 nd and Tuesday the 3 rd April: The majority of delays were attributable to ATC industrial action that took place in France; Marseille and Bordeaux ACCs were strongly affected and recorded very high delays. Madrid ACC also suffered from the French strike and registered delays due to it. The second main reason for delays was en-route ATC capacity and was recorded in Barcelona, Madrid, Brest and Nicosia ACCs. Tirana generated significant delays on the 3 rd due to the new ACC implementation. Tallinn recorded delays due to the implementation of the new ATC system.

6. ALL AIR TRANSPORT DELAYS (Source: CODA) The analysis below is based on airline data provided to CODA by airlines (AO's). As the airline data collection for April 212 is not yet complete at the time of writing, this analysis covers the latest available 13-month period (Mar 211-Mar 212) and contains details on 58% of commercial flights in the ECAC region. ATFM delays reported by airlines are often lower than the ATFM delays calculated by the network manager (NM). ATFM delays of NM are the (flight) planned delays whereas the airlines report the actual experienced ATFM delay on departure. For instance, a flight with an ATFM delay may also have a handling delay absorbed within the ATFM delay. For the airline, a part of this delay is the ATFM delay and the rest is the handling delay Average departure delay per flight in minutes 9 8 7 6 5 4 3 2 1 Breakdow n average delay per flight March 212,3 Average En- Route Delay/Flight,2 Average En- Route Delay/Flight Reactionary delay Primary Delay (excl En-Route) Airline Reported En-Route ATFM Delay NM reported En-Route ATFM delay 4, Average primary delay 7,8 Passenger experience Airline reported en-route ATFM delay in March 212 was.2 minute per flight which is slightly below the NM reported average en-route ATFM delay of.3 minute per flight. As airlines may assign multiple delay reasons for a delayed flight, some of the en-route ATFM delay may be attributed to other reasons if the other reason prevented the flight from obtaining a slot improvement. A common example is a NM reported en-route ATFM delay reported by airlines as a split between reactionary and en-route ATFM delay. According to airline reports, in March 212 the average delay per flight for all-causes of delay was 7.8 minutes. Primary delay share of total all-causes delay was 51% (or 4. min/flt) of which en-route delays contributed.2 min/flt. The remaining were Reactionary delays, this counted for 49% or a contribution of 3.8 min/flt.
