3 1. TOTAL TRAFFIC 32 Last 13 months average daily traffic 32 Average daily traffic for last 5 Years In December 212, traffic decreased significantly by 5.6% compared to December 211. Traffic in December 212 was the lowest of the last five years Average daily traffic in December for last 5 Years forecast date : % 3% 2% 1% -1% -2% -3% 3.1% % 12 months rolling traffic trend 1.6 %.2% -% -.6% -.9%-1.2% -1.7% -1.9% -2.1% -2.6% December 212 traffic was significantly below the forecast. The extended Christmas-week shut-down period was the main factor for this drop. This graph shows the variation in average daily traffic for the last 12-month period relative to that for the 12-month period before. The average daily traffic from January 212 to December 212 decreased by 2.6% relative to that from January 211 to December 211. DNM Network Operations Report Analysis - December 212 1

4 In December 212, nine of the top 1 airports had less traffic compared to December 211. The largest traffic decrease (-19.5 %) was at Budapest Ferihegy airport due to Malév Hungarian Airlines ceasing operations in February 212, followed by 16% drop at Las Palmas airport due to Islas Airways ceasing operations in October 212. The 17.4% traffic decrease at Madrid Barajas airport is the result of overall traffic reduction in Spain in conjunction with Spanair cessation of operations in January 212. Athens airport recorded a real traffic reduction of 17%.Traffic at Stuttgart airport decreased by 11.4% following Contact Air ceasing operations at the airport. The largest traffic increases were at Venice (+15.), Istanbul Ataturk (+12.6 %), Istanbul Sabiha (+11.2%) and Tel Aviv (+6%) airports. Three of the top 1 air operators had significantly increased traffic in December 212 compared to December drop in Lufthansa traffic was partly due to Contact Air ceasing operations (under the DLH callsign). Airline consolidation and restructuring explains most of the significant traffic decreases and increases: Air Nostrum (-36.9%) and Finnair (-31.), Olympic (-27.8%), BAW shuttle (+31.9% due to the cessation of BMIbaby operations in September) and Finnish Commuter Airlines (+31.6%). Aeroflot Russian (+19.4%) recorded a real traffic growth. Unidentified operators (mainly General Aviation) decreased by 5. in December 212. DNM Network Operations Report Analysis - December 212 2

Figures are the average daily delays in minutes. London Heathrow, Amsterdam, Frankfurt, Munich, Stockholm, Zurich, Geneva, Vienna and Madrid airports were affected by seasonal weather throughout the month with low visibility, fog, wind and snow issues. Paris ACC s delays were caused by ATC capacity issues and the change of the airspace design (IRP: Interface Reims Paris). Langen, Lisbon and Warsaw ACCs recorded delays due to en-route ATC capacity, ATC staffing and disruptions. Karlsruhe ACC was affected by VOLMUK. Delays in Ankara ACC were due to reduced ATC Capacity in ORBB (Baghdad) FIR (NOTAM A15/12). Runway configuration at Canarias island airports due to southerly winds caused delays at Canarias ACC. Lisbon airport registered delays due to capacity and due to bad weather conditions (low visibility). Brest ACC generated delays due to ATC capacity, to the strike that took place on the 7 th December and between the 18 th and the 2 th December due to the paperless strip system trial. The limited use of the optimum runway configurations at Zurich airport (due to environmental constraints) and at Istanbul Ataturk airport (due southerly winds) continued to cause delays.

13 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 December 212 is not yet complete at the time of writing, this analysis covers the latest available 13-month period (November 211-November 212) and contains details on 59% 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 Breakdow n average delay per flight Nov 212,4 Average En- Route Delay/Flight,3 Average En- Route Delay/Flight NM reported En-Route ATFM delay Primary Delay (excl En-Route) 4,3 Average primary delay 7,4 Passenger experience Airline Reported En-Route ATFM Delay Reactionary delay Airline reported en-route ATFM delay in November 212 was.3 minutes per flight which is slightly lower than the NM reported average en-route ATFM delay of.4 minutes 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 reporting, in November 212 the average delay per flight for all-causes of delay was 7.4 minutes. The primary delay share of total all-causes delay was 58 % (or 4.3 min/flight) of which en-route delays contributed.3 min/flt. The remaining were Reactionary delays, this counted for 42% or a contribution of 3.1 min/flight. 15 Average departure delay per flight 211/212 Average departure delay (min) per flight Based on airline data, the reported share of reactionary delay minutes in November 212 was 42%. Both NM and airlines reported that en-route ATFM delays were below 1 minute per flight at.4 min/per flight and.3 min/per flight respectively.

14 7. ATFM SLOT ADHERENCE Average daily evolution of early and late flights Nº OF EARLY DEPARTURES Nº OF LA TE DEP A RTURES % EARLY DEPARTURES % LATE DEPARTURES In December the percentage of late non-compliant departures increased significantly compared to the previous month. This is mainly caused by snow and de-icing conditions at some major airports in the beginning of December. The percentage of early departures has remained stable. Although the overall percentage of traffic departing within their Slot Tolerance Window (STW) is above the target (at least 8), there are many airports for which compliance can be improved. Due to the winter conditions the absolute number of flights departing outside the STW has slightly increased. The chart below shows the airports that have more than 3 regulated flights during the month with their average daily number and proportion of regulated flights that departed outside of the STW. Any airport above the red line is non-compliant with the ATFM slot adherence target (min 8) and non-compliant departures from Lisbon, Zurich, Paris Orly and Geneva airports have wider network impact Proportion of regulated flights outside the Slot Tolerance Window in December ISTANBUL-ATATURK LISBOA HELSINKI-VANTAA WARSZAWA/OKECIE PARIS ORLY SCHIPHOL BALE-MULHOUSE ZURICH PARIS CH DE MANCHESTER STUTTGART TEGEL-BERLIN GENEVE COINTRIN KOELN-BONN NICE DUBLIN DUESSELDORF LONDON/HEATHROW COPENHAGEN PRAHA RUZYNE LYON SATOLAS VENEZIA TESSERA HAMBURG TENERIFE SUR ROME FIUMICINO LONDON/GATWICK MUENCHEN 2 PORTO WIEN SCHWECHAT LAS PALMAS BRUSSELS OSLO/GARDERMOEN MILANO MALPENSA MADRID BARAJAS MILANO LINATE BARCELONA 8. SIGNIFICANT EVENTS AND ISSUES 8.1. PLANNED EVENTS The significant events planned for the month of December 212 were mainly related to training and operational trials for new ATM systems. VOLMUK operational trials took place in Karlsruhe and Munich ACC's over the weekend of 7-1 December 212 with an estimated 2 capacity reduction on each ACC in anticipation of transition to full operations from 15 and 16 December respectively. The event had a small network impact. Budapest (1-3 December 212) and Bratislava (1-21 December 212) entered into shadow mode operations in anticipation of transition to new operational facilities, with Budapest ACC initiating parallel operations from 4-17 December 212. Low impact with no capacity reductions were foreseen for either event. These events had negligible network impact. Due to the implementation of the new airspace design in Paris and Reims ACC's there was a reduction in capacity of approximately 2 until 17/12. After 18/12 capacity was reduced by 1 with a view to normal operations by 14/1/13. The event had some network impact DISRUPTIONS 2/12/212: Ankara - Zero rate applied in Ankara CTA from 63-93utc due to total power failure (4 flights, 761 mins delay). 6/12/212: Toulouse/Blagnac utc, radar unserviceable, zero rate applied (118 flights regulated, 4,192 mins delay). 14/12/212: EPWW - ATC Equipment (OLDI) failure in conjunction with staffing and capacity issues (123 flights, 12 mins delay) OTHER CONSTRAINTS There were no other constraints with network impact in December 212.
