October 2012 traffic was significantly below the forecast. 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 November 2011 to October 2012 decreased by 1.9% relative to that from November 2010 to October 2011.

DNM Network Operations Report – Analysis - October 2012 1

Eight of the top 10 airports had less traffic compared to October 2011 (Paris CDG, London Heathrow, Amsterdam, Munich, Madrid Barajas, Rome Fiumicino, Barcelona and Vienna). Frankfurt and Istanbul Ataturk airports had increased traffic. The largest decrease was at Budapest Ferihegy (-20.1 %) airport as a result of Malév Hungarian ceasing operations in February 2012. The next largest decrease was at airport (-17.1%) as a result of Islas Airways ceasing operations on 16 October 2012, followed by Prague (-14.6%) airport. The 12% traffic decrease at Madrid Barajas airport is the result of overall traffic reduction in in conjunction with cessation of operations in January 2012. The largest traffic increases were at Istanbul Sabiha (+15.2%), Istanbul Ataturk (+11.5%), Dublin (+11%) and Toulouse Blagnac (+10.9%) airports. The growth in Istanbul airports is in line with the ongoing traffic growth of Turkish Airlines and Pegasus Airlines. With the exception of Alitalia, the traffic for the top 10 air operators (Lufthansa, Ryanair, Easyjet, Air France, Turkish Airlines, SAS, Air Berlin, British Airways and KLM) increased in October 2012 compared to October 2011. consolidation and restructuring explains most of the significant traffic decreases and increases: (-33%), Czech Airlines (-32.9 %) and Finnair (-14.6%), United Airlines (+116.4%), BAW shuttle (+34.4% due to the cessation of BMIbaby operations in September) and Monarch airlines (+19%). Aeroflot Russian (+28.9%) and Loganair (+20%) recorded a real traffic growth. “Unidentified operators” (mainly General Aviation) decreased by 2% in October 2012.

DNM Network Operations Report – Analysis - October 2012 2

Traffic increased significantly at Makedonia, Dnipropetrovsk, Dublin and Stavanger ACCs. Malta recorded an increase of 33.5% compared to October 2011 as a recovery from last year’s Libyan airspace closure. Traffic decreased significantly at Santa Maria, Canarias, Yerevan, Brindisi, Tampere and Budapest ACCs.

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 October 2012 is not yet complete at the time of writing, this analysis covers the latest available 13-month period (September 2011-September 2012) and contains details on 65% 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.

s Breakdow n average delay per flight Sep 2012 Airline reported en-route ATFM delay in September 2012 was 10 8,9 9 0.5 minutes per flight which is slightly lower than the NM 8 reported average en-route ATFM delay of 0.8 minutes per 7 flight. As airlines may assign multiple delay reasons for a 6 5 4,8 delayed flight, some of the en-route ATFM delay may be 4 attributed to other reasons if the other reason prevented the 3 flight from obtaining a slot improvement. A common example is 2 a NM reported en-route ATFM delay reported by airlines as a 1 0,8 0,5 0 split between reactionary and en-route ATFM delay.

The percentage of early departures has increased. Although the overall percentage of traffic departing 400 4.0% within their Slot Tolerance Window (STW) is above the target 300 3.0% (at least 80%), there are many airports for which compliance 200 2.0% can be improved.

The chart below shows the top 40 airports that have more than 300 regulated flights during the month with their average daily number and proportion of regulated flights that departed outside of the STW. Although any airport above the red line is non-compliant with the ATFM slot adherence target (min 80%), Antalya, Tel Aviv/Ben Gurion and Birmingham airports have wider network impact.

SIGNIFICANT EVENTS AND ISSUES

8.1. PLANNED EVENTS The significant events planned for the month of October 2012 were related to training for new ATM systems to be deployed in the coming months. The training took place in: Vienna, Munich, Budapest, Bratislava, Ljubljana, Stockholm, Warsaw ACCs and Warsaw TMA. In all cases NO reductions in sector capacities were originally foreseen, although Munich ACC estimated Medium impact and Warsaw ACC estimated Medium to High impact on network performance. There was no significant impact on the network from these trainings.

8.2. DISRUPTIONS ¾ Greek Industrial Action on 18 October: ATC personnel in Greece participated in a general industrial action on 18 October 2012 from 07:00 until 10:00 UTC. The action led to no noticeable flight cancellations while generating 1403 minutes of ATFM delay (6% of the daily network delay). This event had minimal impact on both the network’s and Greek ACC’s annual delay results. ¾ Industrial Action on 22-24 October in France: ATC personnel in France had a general industrial action from Monday 22 October 2012 17:30 UTC until Wednesday 24 October 04:30 UTC. The action did not lead to significant flight cancellations but some diversions. It generated 69,300 minutes of direct industrial action delays in France (34% of the daily network delay) with an additional 1058 minutes of ATFM delay in Spain due to diversions. This event is considered as a medium disruption and will have some impact on both network’s and on French ACCs’s annual delay results. ¾ Hurricane Sandy on 28-29-30 October: Hurricane Sandy had no impact on network delays but did impact the North Atlantic traffic with an estimated 1000 fewer flights.

8.3. OTHER CONSTRAINTS ¾ Staffing Issues at Langen ACC: ATC Staffing levels at Langen ACC appear to be a continuing issue. In conjunction with 2.6% en-route traffic growth in October, Langen ACC delays were again the highest of the network in October. ¾ Staffing Issues at Lisbon ACC: ATC Staffing levels at Lisbon ACC started to be a problem in the course of October. Traffic in Lisbon ACC reduced 6% compared to 2011 in October 2012. 9. NM ADDED VALUE
