Good Friday dip that typically occurs during Easter, an extra week of the winter schedule occurring during the month and two airline strikes (Lufthansa and Iberia) contributed to the traffic decline in March 213. 1.6 % 1% 1% -1% -1% - - -3% -3% -4%. 12 months rolling traffic trend -% -.6% -.9%-1. -1.7% -1.9%-2.1% -2.6% -2.6% -2.8% -2.8% This graph shows the variation in average daily traffic for the last 12-month period relative to that for the 12-month period before.

In March 213, 9 of the top 1 airports had less traffic compared to March 212. The largest traffic increases were recorded at Istanbul Sabiha Gokcen (+13.8%), Istanbul Ataturk (+12.7%) and Tel Aviv Ben Gurion 1 (+12.) airports. The largest traffic decreases were at Athens (-16.1%) and Hamburg (-12.6%). The 14.7% traffic decrease at Madrid Barajas airport was due to overall traffic reduction in Spain in conjunction with Iberia strike(s). Only 4 of the top 1 air operators had increased traffic in March 213: Turkish Airlines 2 (18.5%), British Airways (12.9%) S.A.S (3.8%) and EasyJet (1.5%). The highest traffic growth was observed at Pegasus (+26.2 %), Emirates (+2) and Aeroflot Russian (+19.6 %). Airline consolidation and restructuring explains most of the significant traffic decreases and increases: Iberia (-39.8%), Air Nostrum (-36.5%), Finnair (-28.9 %), Olympic (-28.5 %), BAW shuttle (+32.7%) and Finnish Commuter Airlines (+33.9%). Unidentified operators (mainly General Aviation traffic) decreased by. in March 213. 1 Ben Gurion is not a network airport but it is adjacent to it. The figures above are only for the traffic to/from network to Ben Gurion. 2 Due to a change in the flight designators of the domestic THY flights since February 213, all domestic THY flights are counted under unidentified operators. This figure reflects the correct situation after such flights are re-assigned to THY. DNM Network Operations Report Analysis March 213 3

The most significant traffic increases occurred in Chisinau, Simferopol, Dnipropetrovsk, Karlsruhe and Nicosia ACCs. The increase of 19.1% in Malta ACC is a continuation of the recovery from the 211 Libyan airspace closure. Traffic decreased significantly in, Skopje, Tampere, Bodo, Milano, Bremen, Madrid and Stockholm ACCs. The decrease in Munich and increase in Karlsruhe is due to the airspace transfer between these ACCs as part of the VOLMUK project. DNM Network Operations Report Analysis March 213 4

Figures are the average daily delays in minutes. London Heathrow airport had the highest delays in March mainly due to strong winds, fog and low visibility. Oslo Gardermoen airport had significantly high delays due to the new SID and STAR procedure implementation. Delays in Nicosia were caused by the ongoing capacity issues which were further reduced on 24 March due to the exceptional circumstances in the country. Vienna ACC delays were expected and caused by the planned reductions during the transition to new COOPANS system. Paris CDG, Berlin, Brussels and Paris Orly airports were affected by weather with low visibility, fog, wind and snow issues. Frankfurt, Zurich, Vienna and London Gatwick airports were affected by weather (snow, wind, low visibility) and airport infrastructure issues mainly linked to the weather conditions. Langen ACC had delays due to staff shortages, ATC capacity and frequency and communications failures on 12, 16, 2 and 22 March. Canarias registered delays due to en-route weather (strong wind) and ATC capacity. Delays in Paris and Brest ACCs were caused by ATC capacity issues, the implementation of airspace changes in Paris ACC and the stripless system trial in Brest ACC. The French industrial action on 5 March also caused some minor delay. Madrid ACC recorded delays due to en-route ATC capacity. Amsterdam and Geneva airports delays were due to fog, wind, snow and airport ATC capacity. Delays in Ankara ACC were due to reduced ATC Capacity in ORBB (Baghdad) FIR (NOTAM A178/12).

The Interface Reims Paris (IRP), the impact of the capacity reductions in Baghdad FIR on Ankara ACC, Vienna transition to COOPANS, implementation of COOPANS in Stockholm TMA and the exceptional capacity reductions in Cyprus have been recorded under en-route events.

6. ALL AIR TRANSPORT DELAYS (Source: CODA) This section presents the all air transport delay situation as seen from the airlines by using the data collected by Central Office for Delay Analysis (CODA) from the airlines. Data coverage is 64% of the commercial flights in the ECAC region for February 213. ATFM delays reported by airlines may be lower than the NM calculated ATFM delays due to difference in methods: ATFM delays of NM are the (flight) planned delays ; 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.

Within all air transport delays, en-route ATFM delays reduced from.3 minutes/flight to.2 minutes per flight in February 213 ( this was a fall of 46%). Primary delays counted for 56% (or 5.3 min/flt ) of which.2 min/flt is attributed to en-route ATFM delays, with reactionary delays representing a 44% share (4.1min/flt) down from 46% in February 212.

According to airline reports, primary delays counted for 56% (5.3 min/flt) of which (.2 min/flt) is attributed to en-route ATFM delays, with reactionary delays representing a 44% share (4.1min/flt).

SIGNIFICANT EVENTS AND ISSUES 8.1. PLANNED EVENTS Vienna ACC successfully implemented the new system COOPANS on 28 February, as planned. Sector capacities were reduced by 5 at the beginning of the implementation, gradually increasing to reach 1 reduction only by the end of March, following the transition plan. Ljubljana ACC successfully moved to the new ops room on 13 March, following 1 days of shadow operations. Sector capacities were reduced by 1 to 2 during one week with no delays. Operations are back to normal since 21 March. Chishinau ACC continued training for the new ATM system to be implemented in April 213, with no impact on network performance and no reduction of sector capacities. Karlsruhe UAC continued the familiarization of ATCOs with the new system and airspace structure in the South sector family (Ex Munich ACC sectors). 8.2. DISRUPTIONS An ATC industrial action in France on 5 March with minimum delay impact. A series of Iberia strikes between 4-8 March with and a Lufthansa strike on 21 March had some impact on network traffic with cancelled flights. The critical financial and economic discussions affecting Cyprus also had a detrimental impact on Nicosia ACC performance on 24 March. DNM Network Operations Report Analysis March 213 13
