NM Monthly Network Operations Report - Analysis - March 2015 2
1. TOTAL TRAFFIC
Traffic increased by 1.4% in March 2015 compared to March 2014.
Average daily traffic in March was above 2013 and 2014 levels but below 2011 and 2012 levels.
March traffic was at the low end of the forecast.
This graph shows the variation in average daily traffic for the last 12-month period relative to previous 12-months. The average daily traffic from April 2014 to March 2015 was 1.4% higher than the average from April 2013 to March 2014. The trend shows a continuous modest recovery in traffic that dates back to April 2013.
The low-cost segment maintained its dominant position with a growth rate around 8% since the beginning of 2015 whereas the all-cargo segment recovered from -1.1% in January to +1.5% in March. Charter was the weakest of the market segments and was down 8.8% on March last year and was followed by business aviation and traditional scheduled, both segments were down 0.9% and 0.2% respectively on March 2014. With circa 230 extra daily flights, UK was the main contributor to local traffic1 and followed by Turkey and Spain each adding 140 and 120 daily flights respectively to the European network. Germany was back among the top contributors and added 70 daily followed by Italy and Greece, both countries adding each 70 flights per day. Portugal, Poland, Ireland, Belgium/Luxembourg and Romania were the other countries adding more than 25 flights per day to the network. At the other end of the scale, the 8-day strike at Norwegian Air Shuttle in March resulted in circa 110 fewer daily flights for Norway (vs. March 2014). The overall traffic decrease in Ukraine was 74% representing a fall of 28% (100 fewer daily flights) in the state’s local traffic and a fall of 98% in its overflights (vs. March 2014). Traffic re-routing via neighbouring states resulted in overflight increases for Bulgaria (+48%), Romania (+25%), Turkey (+21%) and Hungary (+20%) and overflight decreases for Moldova (-60%) and Armenia (-30%). The closure of the Libyan airspace shifted eastwards traffic flows between North West Europe-Southern Africa resulting in overflights increases for Greece (+15%) and decreases for Malta (-22%).

12 months rolling traffic trend
NM Monthly Network Operations Report - Analysis - March 2015 3
Six of the top 10 airports recorded positive traffic growth compared to March 2014. Overall, the largest traffic increases in March 2015 were at London/City, Athens, Istanbul/Sabiha Gokcen, London/Stansted, Dublin, London/Luton, Birmingham, Lisbon, and Warsaw airports. London/City traffic increased significantly mainly due to the start of Flybe operations. The largest traffic decreases were at Oslo/Gardermoen, Bergen/Flesland, Prague, Gran Canaria and Milano/Malpensa airports. Five of the top 10 aircraft operators had more traffic compared to March 2014. Overall, the operators with the highest traffic growth were Germanwings, CityFlyer Express, Wizz Air and Vueling. Lufthansa, Norwegian Air shuttle, Finnish Commuter Airlines, Transavia, Air Baltic and HOP recorded the highest traffic decrease compared to March 2014. The 8-day strike at Norwegian Air Shuttle influenced its traffic decrease. The transfer of certain Lufthansa flights to Germanwings accounted for some of the variation in traffic in these carriers. Pegasus continued to record an increase in flights compared to March 2014 following an increase in fleet size.
NM Monthly Network Operations Report - Analysis - March 2015 4
The large traffic changes in the Italian ACCs are due to resectorisation in April/May and November 2014. Traffic avoiding the Ukraine airspace continues to increase traffic flows in Sofia and Bucharest ACCs, but with a significant traffic decline continuing in Chisinau and Yerevan ACCs. Skopje ACCs traffic increase continued in March following the re-opening of the Kosovo KFOR sector in April 2014 and an increase in traffic to Skopje airport. Increased traffic in Athens, Makedonia and Nicosia ACCs is due to traffic avoiding Libya and Syria. Malta ACC continues to be affected by the changes in Libyan airspace availability. Beograd, Budapest, Reykjavik, Cairo and Santa Maria ACCs experienced a significant increase in traffic.

2. ATFM DELAY AND ATTRIBUTIONS
Total ATFM delays increased by 21.9% in March 2015 compared to March 2014.
En-route ATFM delays decreased by 42.9% but airport ATFM delays increased by 157.2% compared to March 2014.
The rolling 12-month trend shows that ATFM delay was 21.9% higher during the period April 2014 – March 2015 compared to April 2013 – March 2014. A similar trend can be observed for the last four months.
Airport weather (39.3%) was the biggest contributor to ATFM delays in March, followed by airport capacity (15.9%) and en-route ATC capacity (15.6%).
These are the top 20 delay generating locations for the reporting month with respect to total ATFM delays . Figures are the average daily delays in minutes for the individual location s.
• Weather (mainly strong wind, snow and low visibility) impacted airport operations, particularly at Amsterdam/Schiphol, London/Heathrow, Zurich, Oslo/Gardermoen airports.
• Nicosia ACC recorded high delays due to ATC staffing/capacity issues. Reduced capacity due to system upgrades and Israeli military activity also contributed to the delays.
• Istanbul/Ataturk and Istanbul/Sabiha Gokcen airports continue to experience delays due to aerodrome capacity issues. • Amsterdam/Schiphol airport’s implementation of VCS (trials and transition) produced delays. • Brest, Reims, Paris, Lisbon and Maastricht ACCs generated delays due to en-route ATC capacity. Brest also generated
delays linked training for ERATO implementation.

NM Monthly Network Operations Report - Analysis - March 2015 7
EN-ROUTE ATFM DELAY PER DELAY GROUP
En-route delays accounted for 31.7% of all ATFM delays. Most of this delay was caused by en-route ATC capacity and en-route staffing ATC issues as explained in detail below. The other causes were:
• En-route Weather: Maastricht and Bremen ACCs were affected by thunderstorm activity and turbulence.
• En-route ATC Disruptions: Delays were recorded due to system update in Nicosia ACC and industrial action in Vienna ACC on the 26 March.
• En-route Capacity: Israeli military activity affected Nicosia ACC on the 31 March.
• En-route Disruptions: System upgrade in Nicosia ACC on the 24 and 26 March was also recorded as disruptions.
Brest and Nicosia ACCs were the biggest generator of en-route ATC capacity delays in March; most of the delay was generated during the weekend in Brest, Reims, Lisbon, Nicosia, Maastricht and Paris ACCs.
Nicosia ACC was the biggest generator of en-route ATC staffing delays in March, delays occurred mainly on Tuesdays, Mondays and during the weekend.
Brest ACC generated en-route events delays on the 21, 22 and 29 March due to training for ERATO implementation. Nicosia ACC had a system upgrade which generated delays and Zurich ACC had some delay due to the new stripless system.
An average of 151 flights per day received an en-route delay of at least 15 minutes in March 2015. The corresponding figure for March 2014 was 252 flights.

4. AIRPORT/TMA ATFM DELAYS AIRPORT/TMA ATFM DELAY PER LOCATION
The top 20 Airport/TMA delay locations generated 64.1% of the monthly total ATFM (network) delay. The top 5 Airport/TMA delay locations generated 51.4% of the monthly total ATFM (network) delay.
AIRPORT/TMA ATFM DELAY PER DELAY GROUPS
Airports accounted for 68.3% of all ATFM delays in March 2015, mainly due to weather and airport capacity constraints.
Strong winds, low visibility and snow impacted airport operations, particularly at Amsterdam/Schiphol, London/Heathrow, Oslo/Gardermoen and Zurich airports. Amsterdam/Schiphol and London/Heathrow were particularly affected by strong winds on the 29, 30 and 31 March.
Istanbul/Ataturk and Istanbul/Sabiha Gokcen airports experienced aerodrome capacity issues.
Amsterdam/Schiphol airport’s implementation of VCS (trials and transition) was the main airport event that generated delays. There were minor delays due to two other events.

Top 10 delay locations for Airport Events in March 2015
NM Monthly Network Operations Report - Analysis - March 2015 11
AIRPORT/TMA ATFM DELAY PER FLIGHT
Average airport/TMA delay per flight increased from 0.19 min/flt in March 2014 to 0.48 min/flt in March 2015.
Amsterdam/Schiphol, London/Heathrow and Zurich airports had the highest delay per flight in March, mainly due to seasonal weather. High traffic for a Convention (10-12 March) caused Cannes delays.
AIRPORT/TMA ATFM DELAY YEAR-TO-DATE
The top 20 Airport/TMA delay locations have generated 69.4% of the total ATFM (network) delay in 2015. The top 5 Airport/TMA delay locations have generated 50.2% of the total ATFM (network) delay in 2015.
5. DAILY EVOLUTION
There were three days in March 2015 where the average delay/flt exceeded 1.5 min/flt; Sun 29, Mon 30 and 31 Tue March 2015 : Strong winds at Amsterdam/Schiphol (79,866 minutes), London/Heathrow (24,813 minutes) and Frankfurt (7,167 minutes) generated high delays. En-route capacity (ATC) issues and training for ERATO implementation in Brest (14,210 minutes). ATC capacity issues at Reims (4,393 minutes) and Nicosia ACC (4,296 minutes). Airport capacity at Istanbul/Ataturk (7,458 minutes) and Istanbul/Sabiha Gokcen (4,412 minutes) also generated delays.

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 65% of the commercial flights in the ECAC region for February 2015. 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.
Based on airline data, the average departure delay per flight from “All Causes” was 9.4 min/flt. This was an increase of 26% in comparison to 7.4 min/flt in the same month in 2014. Within all air transport delays, en-route ATFM delays were 0.1 min/flt in February 2015. Primary delays counted for 57% (or 5.3 min/flt) of which 0.1 min/flt was attributed to en-route ATFM delays, with reactionary delays representing a smaller remaining share of 43% at (4.1 min/flt).
Further analysis of airline data shows that the average en-route ATFM delay was 0.1 min/flt. This was the same as the NM reported average en-route ATFM delay of 0.1 min/flt.
The percentage of flights subject to long ATFM restrictions (those exceeding 15 & 30 minutes) increased slightly with flights with restrictions exceeding 15 minutes at 1.5%. The percentage of flights delayed from all-causes also increased (those exceeding 15 minutes) increased by 3.4 percentage points to 15.1% and those (exceeding 30 minutes) also increased to 7.2%.
NM Monthly Network Operations Report - Analysis - March 2015 13
7. ATFM SLOT ADHERENCE
Both percentages of early and late departures decreased significantly in March 2015.
The chart below shows the 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 Slot Tolerance Window (STW). Any airport above the red line is non-compliant with the threshold (20%). Those airports with a significant number of departures outside the slot tolerance window can reduce network predictability.
8. SIGNIFICANT EVENTS AND ISSUES PLANNED EVENTS ACCs During March, six ACCs carried out projects involving ATM system upgrades, all of which were categorised as special, planned events with potential impact on the network performance. The performance of the network was affected as follows: Madrid ACC The implementation and transition to SACTA CF 2 system: the project was in its post-transition phase until 05 March, and generated 385 minutes of delay (no capacity reductions previously estimated). This represented over 23% of all delays (1,613 minutes) for Madrid ACC during March. Zurich ACC The implementation of the Stripless CH system, Step 3: the project was completed on 10 March generating 4536 minutes of delay (previously estimated capacity reductions 10-20%). This represented over 61% of all delays (7,396 minutes) for Zurich ACC during March. Brest ACC Performed training for the implementation of the ERATO Electronic Environment throughout March generating 6,044 minutes of delay (Medium network impact estimated). This represented over 23% of all delays (25,797 minutes) for Brest ACC during March. Bordeaux, Munich, and L’viv ACCs performed training for the operational staff for the system upgrade projects (L’viv started transition phase on 16 March). Bordeaux training was expected to have a medium network impact and no impact was expected for the other two - no delays were recorded for all three.

Proportion of regulated flights outside the Slot To lerance Window in March 2015
NM Monthly Network Operations Report - Analysis - March 2015 14
Outside of the NOP transition plan there was:
• system upgrades in Nicosia ACC on 24, 26, 27 and 30 March (total of 14,105 minutes). • Ukrainian ACCs implemented night FRA on 05 March, above FL275 with no ATFM delays generated.
Airports Special events:
• Geneva Car Show was held from 3-15 March with no impact on Geneva airport operations despite heavy traffic during Press Days (3 and 4 March).
Local plans in March:
A number of airports undertook infrastructure and technical system improvement work during March. Other than Amsterdam/Schiphol, these improvements had at most a minor impact on local airport operations.
Completed: • Maneuvering area (runway, taxiways and/or apron) improvements at Barcelona/El Prat, Nice/Cote D’Azur and
Rome/Fiumicino airports; • ILS maintenance at Palma de Mallorca airport.
On-going: • Maneuvering area (runway, taxiways and/or apron) improvements at Athens/E. Venizelos, Bari/Palese, Bologna,
Dublin, Frankfurt/Main, Gran Canaria, Katowice/Pyrzowice, Krakow/Balice, Lisbon, Manchester, Oslo/Gardermoen, Palma De Mallorca, Paris/Ch. De Gaulle and Warsaw/Chopin airports;
• Terminal building(s) improvements at Bergen//Flesland, Budapest/Ferihegy, Gran Canaria, Katowice/Pyrzowice, Krakow/Balice, Munich, Nuremberg, Oslo/Gardermoen and Warsaw/Chopin airports;
• ILS maintenance at Dusseldorf and Valencia airport; • Construction of a new runway at Katowice/Pyrzowice airport; • PBN implementation (RNP APCH based on GNSS approach) at Belgrade/Nikola Tesla airport; • Implementation of a new voice communication system (VCS) at Amsterdam/Schiphol airport recorded high delays
during two operational trial weekends on 7-8 and 14-15 March and transition period that started on 21 March (total delays: 34,178 minutes).
DISRUPTIONS Technical
• A late morning ILS calibration at Pisa/San Giusto on 19 March triggered an arrival regulation immediately followed by aerodrome capacity arrival regulation (482 minutes);
• There was a huge power failure in Netherlands on 27 March between 0900 and 1000. Amsterdam/Schiphol (5,428 minutes), Rotterdam/The Hague and Eindhoven airports were impacted during and after the failure.
Industrial action • Industrial action – reduced configuration at Warsaw ACC due to staff meeting on the 26 March (1,014 minutes); • Italian industrial action on 20 March with 4,489 minutes of airport ATFM delay and minimal en-route impact. • Lufthansa pilot strike on the 18, 19 and 21 March, approximately 855 flights did not operate; • 8-day strike at Norwegian Air Shuttle in March resulted in circa 110 fewer daily flights in Norway.
Other
• A bomb disposal in the afternoon at London City airport on 24 March. It was necessary to reduce the arrival rate to 10/hour and implement a regulation from 1500 (cancelled at 1923) (total delays: 1,194 minutes);
• Work in progress caused single runway operations (capacity reduction) at Barcelona/El Prat on 29 March (total delays: 831 minutes).

9. NM ADDED VALUE
RRP DIRECT DELAY SAVINGS NM proposed alternative routes to an average of 41flts/day in March 2015, of which 15 were accepted. This saved daily 112 minutes of delay and 107 nautical miles. This graph shows the actual daily averages for the previous 13 months period.
FLIGHTS WITH DELAY > 30’ The number of flights that had more than 30 minutes of ATFM delay increased by 29.2%, from 113 flts/day in March 2014 to 146 flts/day in March 2015. 71.2% of flights with more than 30 minutes of ATFM delay in March 2015 were airport and 28.8% were en-route.
