1 Delays decreased in September 2012, with airline delay data for all causes showing an average delay per delayed flight of 25 minutes, this was a decrease of 9% in comparison to the delays observed in September 2011.

2 FOREWORD This report gives an overview of the delay situation in the European Civil Aviation Conference Area. This report has been prepared by the Central Office for Delay Analysis (CODA), a service of EUROCONTROL. It is based on the EUROCONTROL CODA database which contains delay data provided directly by airlines. The report consists of an overview of the reporting period, a summary of the main delay effects, and a series of charts and graphics, which illustrate the main characteristics of the reporting period. A glossary of terms and abbreviations used throughout the report is given in Annex 1. Airline data from the CODA database contains real recorded delays provided to CODA by airlines and is based on the difference between scheduled time of departure and actual off block time. This report discusses delays from all-causes; for information regarding ATFCM delays see the complementary reports available at Table of Contents 1.

3 1. Headlines and Overview. September 2012 saw a reduction in all causes of delay when compared to September Lufthansa cabin crew strikes on 4 th and 7 th of September impacted Frankfurt airport with an estimated 1,000 cancelled flights. Lisbon experienced delays from ATC and capacity delays. London Heathrow, Frankfurt, Palma de Mallorca, Manchester and Amsterdam airports saw delays from weather, predominantly high winds, rain and thunderstorm activity. The average delay per delayed flight (ADD) for departure traffic decreased by 3 minutes to 25.3 minutes per flight. In regard to arrival delay, this fell by 2 minutes per flight. The percentage of flights delayed (by 5 minutes or more) decreased by 4 percentage points to 35.3% on departure and by 4 percentage points for arrivals to 33%. Figure 1.

4 Analysis of the delay causes contributing to the September 2012 average delay per flight of 9 minutes (Figure 3) shows a decrease in the contribution of reactionary delay, this was down from 4.8 to 4.1 minutes per flight. Airline related delay remained at a stable level of 2.9 minutes per flight. ATFM en-route related delays decreased by 56% to 0.5 minutes per flight in comparison to 1.1 minutes per flight in September Note: IATA Delay Code 19 (Passengers with Reduced Mobility) is included in airline grouping Figure 3.

5 Figure 5. ATFM Share of All-Causes Primary Delay. Looking further into the history of the ATFM proportion of primary delay (Figure 5), the en-route percentage share of the total primary delay minutes was 9.9%, this was the lowest share noted since August The share of ATFM airport delay decreased by 1 percentage point, ATFCM airport delay minutes also fell by 24% (Figure 4). EUROCONTROL 5 CODA

6 2. All-Causes Departure Delay Summary 1 The average delay per flight from all causes of delay decreased compared to September 2011 by 17%, to 9 minutes per flight (Figure 6). In September 2012, 45% of flights departed within the 5 minute threshold before or after the scheduled departure time. Flights departing >5 minutes ahead of schedule increased by 2 points to 20% (Figure 7) Figure 6. Average delay per flight (All-Causes) for Departures Figure 7. All-Causes Departure Punctuality 2011 vs A flight is considered delayed as from 5 minutes. The analysis was based on airline data provided to CODA. Unless otherwise mentioned, a flight is considered delayed/advanced as from 5 minutes. EUROCONTROL 6 CODA

Primary and reactionary all-cause delay, by IATA code (%) Figure 9 shows that: Reactionary delay and Technical and Aircraft Equipment saw a decrease in their contribution to the average delay per flight in minutes but their overall share of delay slightly increased compared to the same period as last year. ATFM En-Route Demand/Capacity delay contribution decreased when compared to September 2011 (0.4 minutes per flight and 3 percentage points). The link from these categories to IATA codes is summarised in Figure 17. EUROCONTROL 7 CODA

Manchester saw delays from arrival weather restrictions (strong winds and low visibility) affecting flights to Heathrow, as well as reactionary delays (see Figure 15). EUROCONTROL 8 CODA

10 3. All-Causes Arrival Delay Summary 2 The average delay per flight on arrival from all causes decreased from 10.7 to 8.7 minutes per flight, a 19% decrease. see Figure 13. Regarding arrival punctuality, 27% of flights arrived on time (less than 5 minutes before or after the scheduled arrival time). The percentage of flights arriving >15 minutes ahead of schedule was 10%, this was a slight increase when compared to September Figure 13.

Weather conditions, particularly low visibility, thunderstorms and winds impacted operations at Frankfurt, London Heathrow, Palma and Amsterdam Schiphol. Southerly winds at Istanbul Ataturk limited the use of the optimum runway configuration Environmental constraints at Zurich airport restricted the use of the optimum runway configuration EUROCONTROL 12 CODA

13 5. 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. The first of the new CODA Scheduling indicators is the Block Time Overshoot (BTO). This indicator describes the percentage of flights with an actual block time that exceeds the scheduled block time. In September 2012 the BTO increased by 1 point to 29% when compared to September This indicates that less flights had an actual block time exceeding the scheduled block time. In comparison to August 2012 the BTO increased by 3 percentage points. Figure 18. Block Time Overshoot (BTO). EUROCONTROL 13 CODA

14 The second of the new indicators is the Delay Difference Indicator - Flight (DDI-F). This shows the difference between arrival and departure 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 DDI-F on European flights in September 2012 was -3.7 minutes per flight, this was a small increase in comparison to September 2011, where the DDI-F was -3.1 minutes per flight. Figure 19.
