5 1 Executive Summary Operational data received directly from airlines by CODA describing delays from all-causes for 2016 illustrated a story of poorer on-time performance in 2016, following a year where ATFM en-route delay from ATC industrial actions as well as ATM system implementations drove higher delays for airlines, with the effect of increasing reactionary delay. The average departure delay per flight ranged from a low of 8 minutes per flight in February to a peak of 16 minutes per flight in July. This translated to an annual average all-cause departure delay of 11.3 minutes per flight, an increase of 0.9 minutes per flight, alongside an increase in daily flights of 2.8% in ECAC. The network experienced its busiest ever day on Friday 9 September Reactionary (knock-on) delay increased contributing 5.1 minutes to the 11.3 minute average delay per flight, a 45% share of delay minutes meaning for every 1 minute of primary delay there were 50 seconds of reactionary delay generated. The range of reactionary delay during the year was wider than airline delay, with a range of 4 minutes being observed from the lows in February of 3.5 minutes per flight and the high in June of 7.5 minutes per flight, a month which also saw a peak in en-route ATFM delay. Delays due to airline operations remained the main cause of primary delay, contributing 3.1 minutes to the average delay per flight. Compared to reactionary delay which doubled during the summer months airline delays remain relatively stable with the 2016 monthly average ranging between 2.5 to 3.5 minutes per flight. Airline reported en-route ATFCM delays increased to 0.8 minutes per flight, with ATC industrial action in France and ERATO implementation in Brest contributing to this increase. Airport operations delay including ATFCM, remained at 1.2 minutes per flight and grouped together was the second highest cause in the share of primary delay. Istanbul s Sabiha Gökçen airport continued to suffer heavy delays with the airport experiencing capacity delays on arrival throughout the year. In contrast, Istanbul Ataturk saw a decrease in delay and fell to 20 th position of the top 20 delay affected airports in Yearly airline arrival punctuality decreased, with 81% of flights arriving within 15 minutes or earlier than their scheduled arrival time (STA) compared to 82% in Operational cancellations increased to 1.6% of planned flights, compared to 1.5% in ATC industrial actions in France were observed in 7 out of the 12 months in Other disruptions occurred within airlines with Air France, Alitalia, Lufthansa and SAS having to cancel flights during the year.

6 2 Traffic and Average Delay per Flight Overview Figure 2. Total Departures per Day in ECAC European flights (ECAC) increased by 2.8% in 2016 compared with Total flights reached 10.2 million flights in 2016 and were close to 2008 traffic levels. Removing the leap day effect, this was a 2.5% growth in average daily terms in 2016 (vs. 2015). This relatively high growth rate was mainly driven by the low-cost airlines and also attributable to lower oil prices throughout the year along with a stable although low economic growth. Further information regarding traffic and forecasts can be found on the STATFOR website and via the STATFOR Interactive Dashboard (SID). Figure 3. Breakdown of the Average Delay per Delay Flight 2015 vs saw an average departure delay per flight of 11.3 minutes for all-causes delay, an increase of 9% in comparison to Analysis of the delay reasons shows that reactionary delays contributed the most to the average with 5.1 minutes per flight. Airline-related delays increased slightly by 0.1 minutes per flight. ATFCM en-route delay had the third highest contribution with 0.8 minute per flight increasing by 0.3 minutes per flight compared to Edition Validity Date: 07/04/2017 Edition: CDA_2017_005 Status: Released Issue 2

Primary Delay Causes 2015 vs Total ATFM delay reported by airlines delay increased to 1.7 minutes per flight with en-route restrictions mainly contributing to the overall increase, Airline and airport delays remained stable, with weather delays slightly increasing in Figure 5. Long Departure Delays >60 Minutes Longer delays (those greater than 60 mins in orange) increased when compared to 2015, mainly driven by the higher delays in June and July 2016 where delays above 60 minutes increased to 6%.

8 Monthly Summary As indicated in the executive summary all-causes delay illustrated deterioration in delay performance during 2016, following a year where ATFM en-route, airport capacity and ATC industrial actions caused delays to airlines. Section 2 provides a month-by-month view, highlighting the particular causes and locations of allcauses delay in further detail. January Operational data from airlines describing all-causes delay showed that the average delay per delayed flight (ADD) remained stable at 27 minutes per flight. The percentage of delayed flights (>=5 minutes) on departure also remained stable this at 38%. January saw an increase of 1.5% in daily flights compared to January The stepped implementation of ERATO system in Brest ACC which extended throughout the entire month generated significant en-route ATFM delays with additional effects on Madrid, Paris, Seville and Canarias ACCs. A French ATC industrial action on 26 January resulted in delays for the French ACCs and airports with additional delay generated by Madrid ACC due to ATFM protective measures. Seasonal weather (fog, strong winds, snow) impacted operations at Schiphol, Zurich, Berlin Tegel, London Heathrow, Oslo, Istanbul Ataturk and Sabiha Gökçen airports. February Airline data describing all-causes delay showed that the average delay per delayed flight (ADD) fell to 24 minutes in comparison to 30 minutes observed in February The percentage of delayed flights (>=5 minutes) on departure was 33%, a decrease of 1.2 percentage points compared to the equivalent month in 2015, this improvement in delay also coincided with an increase in daily flights of 3.0% in ECAC compared to February 2015 (adjusted to take in the effect of the 2016 leap year). The stepped implementation of ERATO system in Brest ACC extended throughout the entire month of February resulting in a 20% planned capacity reduction. A local Italian industrial action at Rome Ciampino airport on 29 February 2016 resulted in ATFM measures. Seasonal weather (fog, strong winds, snow) impacted operations at Schiphol, London Heathrow, Geneva, Frankfurt, Brussels, Istanbul Ataturk and Sabiha Gökçen airports, however this was less prevalent than in February 2015 a month with high weather related delay. March Data from airlines describing all-causes delay showed that the average delay per delayed flight (ADD) increased by 1.5 minutes to 27.5 minutes per flight. The percentage of delayed flights (>=5 minutes) was 38%, an increase of 4 percentage points when compared to March In a continuation of the upward trend daily flights also increased, these by 2.2% for the month. Following the terrorist attack at Brussels airport on 22 March, a zero rate measure was applied with Liege, Ostend, Amsterdam Schiphol, Düsseldorf and Charleroi airports taking the majority of diverted flights. Brussels airport was closed for passenger traffic until 1 May. French ATC industrial actions on and 31 March resulted in delays for the French ACCs and airports with additional delay reported by Madrid, Maastricht and Barcelona ACCs due to ATFM protective measures; Seasonal weather (fog, strong winds, snow) impacted operations particularly at London/Heathrow, London/Gatwick, and Brussels airports. April Operational data from airlines describing all-causes delay showed that the average delay per delayed flight (ADD) decreased by 2 minutes to 23.7 minutes. The percentage of delayed flights (>=5 minutes) was 36%, a decrease of percentage points when compared to the same month in Following ATC staffing issues ATFM delays were generated in Brussels, Liege and Charleroi airports. Due to London TMA ATC staffing issues at Swanwick, ATFM delays were generated for several days in April for flights operating through London Stansted, London Luton and London Gatwick airports. ATC industrial actions in Italy and France generated airport and en-route ATFM delay. The industrial action of ground personnel in Germany resulted in approximately 1,300 flights not operating at several German airports. Seasonal weather (fog, strong winds, thunderstorms) impacted operations particularly at London/Heathrow, Istanbul/Sabiha Gökçen, Frankfurt, Zürich and Amsterdam/Schiphol airports. May Airline data from airlines describing all-causes delay showed that the average delay per delayed flight (ADD) increased by 1 minute to 26 minutes. The percentage of delayed flights (>=5 Edition Validity Date: 07/04/2017 Edition: CDA_2017_005 Status: Released Issue 4

9 minutes) was 41%, an increase of 3 percentage points when compared to the same month in ATC industrial actions in France generated airport ATFM delay and en-route ATFM delay on 19 and 26 May. Seasonal weather (strong winds, thunderstorms) impacted operations particularly at Paris/Orly, London/Heathrow, Istanbul/Ataturk, Frankfurt, Zürich, Barcelona and Amsterdam/Schiphol airports. Aerodrome capacity issues generated ATFM arrival delays at Istanbul/Sabiha Gökçen, Istanbul/Ataturk, Amsterdam/Schiphol, Paris/Orly, Zurich and Barcelona airports. June Data from airlines describing all-causes delay showed that the average delay per delayed flight (ADD) increased sharply by 6 minutes to 31 minutes, following a month with higher traffic levels, ATC industrial action as well as weather delay affecting both airports and en-route. The percentage of delayed departing flights (>=5 minutes) increased by 8 percentage points to 51% when compared to the same month in ATC industrial action in France on 12, 13, 14, 23 and 28 June generated airport and en-route ATFM delay during the month. Seasonal weather impacted operations particularly at Istanbul/Sabiha Gökçen, Frankfurt, London/Heathrow, London/Gatwick, Amsterdam/Schiphol and Zurich airports. Aerodrome capacity issues generated delays at Istanbul/Sabiha Gökçen, Istanbul/Ataturk, Barcelona, Zurich, Amsterdam/Schiphol and London/Gatwick airports. July Operational data from airlines describing all-causes delay showed that the average delay per delayed flight (ADD) increased by 2 minutes to 30 minutes, with the percentage of delayed flights (>=5 minutes) also increasing, this by 5 percentage points to 53% when compared to the same month in The ATC industrial actions in France on 4 and 6 July generated airport ATFM delay and en-route ATFM delays. Industrial actions by Air France pilots on 27 July and Alitalia pilots and cabin crew on the 5 July resulted in 1400 and 142 flights being cancelled respectively. Aerodrome capacity generated delays at Istanbul Sabiha Gökçen, Istanbul Ataturk, Barcelona, Paris Orly, Amsterdam Schiphol and Zurich airports. Seasonal weather impacted operations particularly at London Heathrow, Amsterdam Schiphol, Barcelona and Zurich airports. August Airline data from airlines describing all-causes delay showed that the average delay per delayed flight (ADD) decreased by 2 minute to 26 minutes. The percentage of delayed flights (>=5 minutes) fell to 45% when compared August In comparison to July the delay situation in August 2016 improved with no industrial action being observed, this improvement also came in conjunction with an increase of 2.2% in the number of flights per day. Airlines in turn saw reductions in reactionary and airline related delays, however these causes remained high contributors to airline delay performance with 73% share of the average delay per flight experienced by airlines. Brest ACC recorded en-route ATFM delays during the month, alongside Maastricht UAC and Barcelona ACC. Aerodrome capacity ATFM delays continued at Istanbul Sabiha Gökçen with Istanbul Ataturk, Paris Orly, Amsterdam Schiphol and Zurich airports also suffering ATFM arrival delays. A security alert at Frankfurt airport on 31 August generated delays and resulted in over 100 flights being cancelled. Paris Orly conducted runway works with high delays being experienced, Brussels airport also closed a runway during August for runway resurfacing with low levels of additional delay. September Data from airlines describing all-causes delay showed that the average delay per delayed flight (ADD) was 25 minutes compared to 26 in September The percentage of delayed flights (>=5 minutes) remained stable at 42%. Analysing the average delay per flight, airline and reactionary delays fell however ATFM en-route delay increased. Friday 9 September saw the highest number of daily flights in ESRA08 with flights recorded. The French ATC industrial action between 14 and 15 September generated airport and en-route ATFM delays. The most affected airports were Marseille and Paris Orly. NM estimated there were 900 fewer flights during the action. An emergency landing at London Heathrow on 9 September and a frequency failure in Brussels ACC on 15 September generated ATFM delays at these airports. Seasonal weather affected Maastricht, Karlsruhe, Marseille, Bordeaux, Barcelona and Scottish ACCs; thunderstorms, heavy rain and/or low visibility impacted London Heathrow, Palma de Mallorca and to a lesser extent, Istanbul Sabiha Gökçen, Istanbul Ataturk, London Gatwick, Barcelona and Zürich airports.

10 October Operational data from airlines describing all-causes delay showed that the average delay per delayed flight (ADD) was 25 minutes and the percentage of delayed flights (>=5 minutes) at 42%, an increase of 2 minutes and 4 percentage points when compared to the same month in Analysing the average delay per flight, airline and reactionary delays fell however ATFM enroute as well as ATFM weather delay increased, however the average delay per flight remained at a low level in a month with record highs of traffic. Seasonal weather affected Maastricht, Marseille and Barcelona ACCs; heavy rain and/or low visibility impacted London Heathrow, London Gatwick, Amsterdam, Zurich, Barcelona, Paris Charles de Gaulle, Paris Orly and Brussels airports. Bucharest Henri Coanda airport suffered from airport delays due to on-going runway maintenance. November Airline provided data describing all-causes delay showed that the average delay per delayed flight (ADD) was 24 minutes, a decrease of 2 minutes. The percentage of delayed flights (>=5 minutes) was 38%, an increase 3 percentage points when compared to the same month in Analysing the average delay per flight, the share of airline related delay increased to 2.8 minutes, reactionary delays fell from 3.7 minutes to 3.4 minutes per flight. However the average delay per flight remained at a low level in a month with record highs of traffic. Aerodrome capacity issues at Istanbul Sabiha Gökçen were observed during the month, however Istanbul Ataturk saw fewer ATFM delays. Seasonal weather affected Canarias ACC, heavy rain and/or low visibility impacted London Heathrow, London City, Amsterdam Schiphol, Stockholm Arlanda, Zurich, Brussels, Barcelona and Oslo airports. Bucharest Henri Coanda airport continued to suffer from delays due to on-going runway maintenance. December All-causes delay showed that the average delay per delayed flight (ADD) was 32 minutes, an increase of 5 minutes following a month where weather affected operations. The percentage of delayed flights (>=5 minutes) was 47%, an increase of 8 percentage points when compared to the same month in Seasonal weather impacted several airports throughout December, especially Amsterdam Schiphol, Madrid Barajas, London Heathrow and London Gatwick. Istanbul Sabiha Gökçen airport continues to generate delays due to airport capacity, Istanbul Ataturk also suffered from airport capacity delays however to a lesser extent.

11 5 Average Delay per Delayed Flight (Departure) The percentage of flights delayed on departure (>=5 minutes) continued to increase over the last 5 years reaching 43% in Regarding the average delay per flight in Figure 6, the higher delays during summer can be observed. Putting these twelve months together the average delay per delayed (ADD) flight was 27.1 minutes, an increase of 1 minute and the highest ADD level observed in the last 5 years. Figure 6.

13 7 NM Versus Aircraft Operator Experience of Delay Figure 12. Breakdown of Average Delay per Flight 2016 vs (Network Manager vs. Aircraft Operator) This section presents the air transport delay situation as seen from the airline and passenger viewpoint (the difference between the scheduled time of departure and the actual time of departure from the gate). Data coverage is 70% of commercial flights in the ECAC region for ATFCM delays reported by airlines are lower than the NM-calculated ATFCM delays due to difference in methods: ATFM delays calculated by NM are the (flight) planned delays based on restrictions applied; the airlines report the actual experienced ATFCM delay on departure. For instance, a flight with an ATFM restriction may also have a handling delay absorbed within the ATFM restriction. For the airline, a part of this delay is the ATFM delay and the rest is the handling delay. Further analysis of airline data shows that the average en-route ATFCM delay from allcauses was 0.8 minutes per flight, this was the slightly below the NM recorded average en-route ATFM delay per flight for the year of 0.9 minutes per flight. As reported by the airlines, primary delays (e.g. passenger and ramp handling delays) counted for 55% (6.2 min/flt) of which (0.8 min/flt) was attributed to en-route ATFCM restrictions, with reactionary delays representing the remaining share of 45% of (5.1 min/flt), resulting in an average departure delay per flight of 11.3 minutes per flight as reported in previous sections.

14 8 Distribution of All Flights by Length of Delay (Punctuality) In 2016 overall departure punctuality levels fell, with 41% of flights departing within the 5 minute threshold before or after the scheduled departure time (STD) when compared to Flights delayed >30 minutes from all-causes increased by 1.1 percentage points during the quarter to 9.8%. Airline arrival punctuality reduced slightly by 1.56 percentage points with 80.5% of flights arriving within 15 minutes or earlier than their scheduled arrival time (STA), compared to 82.2% in Figure 13. All-Causes Departure and Arrival Punctuality 2015 vs Flights arriving >15 minutes ahead of schedule fell by 0.2 percentage points to 9.3%. This high share may affect airport (stand availability) and air traffic flow management operations (demand shifts) in the event of aircraft frequently arriving excessively ahead of their schedule.

16 9 CODA Operational Flight Cancellation Analysis These results are based on operational cancellation data supplied by 30 European coordinated airports reporting to CODA under EC Regulation N 390/2013. Albeit based on data supplied by a restricted list (see the conditions below) of major European airports, these results already give a good indication of trends and effects of Network events like industrial actions or extreme weather. The IFR flight coverage at the individual airports included in this analysis reaches 100%. Those airports currently unable to report operational cancellations in the required data format or those not meeting all of the criteria for operational cancellations were excluded from the analysis. According to Annex IV of EC Regulation N 390/2013 an Operational Cancellation means an arrival or departure scheduled flight to which the following conditions apply: The flight received an airport slot, and The flight was confirmed by the air carrier the day before operations and/or it was contained in the daily list of flight schedules produced by the airport operator the day before of operations, but The actual landing or take-off never occurred. Therefore this section of the CODA Digest reports on monthly and daily shares of operational cancellations of the total planned flights at day -1. Like delays, operational cancellations provide an insight into the impact of network events and associated disruption; e.g. industrial action or extreme weather events. Figure 16. Monthly Rate of Operational Cancellations Edition Validity Date: 07/04/2017 Edition: CDA_2017_005 Status: Released Issue 12

17 Figure 17. Average Daily Cancellation Figure 16 shows the monthly rate of operational cancellations and Figure 17 provides the detail of cancellations by day from January 2015 to the end of December It should be noted that initial cancellations count as operational cancellations under the terms of the regulation. ATC industrial action occurred in France on the 26th January, with a peak in cancellations being observed of 4%. March saw higher cancellations following a terrorism incident at Brussels Airport on March 22, in the same week ATC industrial action in France ran for 3 days (20, 21, 22 March) and a further day on 31 March with a peak in operational cancellations of 5.6% being observed. ATC industrial actions occurred in Italy and France on 9 and 27, 28, 29 April respectively. Industrial action by ground personnel in Germany on 27 April resulted in approximately 1,300 flights not operating at several German airports. In May there was further ATC industrial action in France generated airport ATFM delay and high en-route ATFM delay on the 19 and 26 May. June saw the most disruption from French ATC industrial action with the 02, 12, 13, 14, 22, 23, 27, 28 June seeing peaks in operational cancellations. There was ATC industrial action in Italy on 16 & 17 June as well as action by pilots of Air France and SAS between the 11 & 14 June and 10 & 14 June respectively. French ATC industrial action occurred on 4 and 6 July. There was also industrial action by Alitalia pilots and cabin crew on the 5 July which saw 140 flight cancellations. Air France pilots also conducted strike action on 27 July. A security alert at Frankfurt airport on the 31 August saw over 100 flights cancelled. In September French ATC industrial action occurred on 14 and 15 of the month. However the overall the daily rates of cancellation remained low for the quarter. Towards the end of the year November saw a peak in cancellations following a strike by Lufthansa between 23 and 30 November.

18 10 CODA Scheduling Indicators Scheduling correctly is a difficult art: if too long a time is blocked for a flight, the airline will not be able to make best use of resources - staff, airframes, infrastructure. But too short a time can arguably be worse as late flights generate rotational delay with late incoming aircraft and passengers from previous flights having to be accommodated. When flights leave on time but arrive after the scheduled time of arrival they cause reactionary delays. Schedule padding is essential for air carriers in order to find schedules which work with the typical patterns of delay, so that they can deliver passengers on time, and get maximum use out of their aircraft. Consequently when delays decrease it takes one or two (IATA) seasons for the airline to adapt its schedule accordingly. The Performance Review Report 2016 also shows the cost of tactical and strategic delay to airlines. Two CODA scheduling indicators help airline schedulers determine the optimal schedule based on historical flight data: The Delay Difference Indicator - Flight (DDI-F) or the difference between departure and arrival punctuality expressed in minutes. This can be indicated as a positive or negative figure, for example a flight departing with 20 minutes delay and arriving with 30 minutes arrival delay will have a DDI-F of +10 minutes. The European DDI-F in 2016 was -3.9 minutes, this was an increase of 0.1 minutes schedule buffering per flight when compared to The Block Time Overshoot (BTO) is the percentage of flights with an actual block time which exceeds the scheduled block time. The European BTO in 2016 was 28%, this stable when compared to 2015 where the BTO was also 28%, indicating a similar number of flights had an actual block time exceeding their scheduled block time during the year.

19 11 CODA Reactionary Delay Analysis In 2016 the share of reactionary delay (IATA delay codes 91-96) was 45% of delay minutes contributing 5.1 minutes per flight. Reactionary delays are generated as a result of an aircraft s late arrival from a previous flight which in turn affects the punctuality of its next flight with the same aircraft, as well as potentially delaying connecting passengers. See IATA Standard Delay Codes section for an overview of the IATA reactionary delay codes. Subsequently there are two types of reactionary delays: firstly as a result of the same aircraft being delayed on its next flight (rotational delay) and secondly when another aircraft is delayed as a result of another aircraft typically through passengers, crew and load connection (non-rotational delays). This section concentrates on IATA delay code 93 rotational delays, as these have a significant share of overall reactionary delays (approximately 90%) and the largest effect on network performance and passenger experience. In Figure 19 analysis shows that the median number of scheduled flights per sequence for an aircraft in 2016 was 4. The changes to the IATA seasons can be observed in the graph where the median fell to 3 in November then falling to 2 in February, as fewer flights may be scheduled during this period. This also highlights that with the shorter sequences of reactionary delay in winter as the network is naturally more resilient in the winter season. The percentage share of rotational delay (IATA delay code 93 only) in 2016 was 41%, an increase of 1 percentage point in comparison to Figure 19.

Breakdown of the Average Departure Delay per Flight by Hour of the Day 2016 (top) vs (bottom) During the first rotation hours (between 0300 and 0900 UTC) Figure 20 shows a higher share of en route ATFM related delay when compared to 2015 with its share above 10% during the first rotation phase at 0600 UTC. This in turn has pushed reactionary delay minutes to over 60% share by the end of the operational day (2100UTC). Figure 20 also illustrates the relative stability of airline delay share during the day. Edition Validity Date: 07/04/2017 Edition: CDA_2017_005 Status: Released Issue 16

21 13 Average Delay per Delayed Flight vs Percentage of Delayed Flights Figure 21. ADD vs. PDF on Departure The percentage of flights delayed on departure (>=5 minutes) increased to 43%. Regarding the average delay per flight in Figure 21, the higher delays during summer can be observed. Putting these twelve months together the average delay per delayed (ADD) flight was 27.1 minutes, an increase of 1 minute and the highest ADD level observed in the last 5 years. The poorer delay performance seen in June and July 2016 can be observed in both figure 21 and 22. Figure 22. ADD vs. PDF on Arrival The average delay per delayed flight on arrival from all-causes was 29.1 minutes per flight in 2016 an increase of 1 minute compared to The percentage of delayed arrivals also increased, this by 1 percentage point to 38% in comparison to 2015, this was also the highest observed in the last 5 years.

Flights at London Luton suffered from airline and en-route ATFM delay affecting airlines. Airlines operating from Spanish airports also recorded reactionary delays predominantly from flights being affected by airline delays as well as industrial action. The effect of weather delay on London Heathrow can also be observed in figure 24. Figure 24.
