12 months rolling traffic trend

NM Monthly Netw ork Operations Report - Analysis – August 2019 TLP: WHITE Page 4

Seven of the top ten airports had positive traff ic grow th. Overall, the largest traff ic increases in August 2019 w ere at Milano/Malpensa, Antalya, Vienna, Tel Aviv/Ben Gurion and Budapest airports. The largest traff ic decreases w ere at Paris/Orly, Stockholm/Arlanda, London/Stansted, Gran Canaria and Berlin/Tegel airports. Additional traff ic due to the temporary closure of Milano/Linate explained the traff ic variation at Milano/Malpensa. Traff ic changes in Vienna are attributed to new entrants.

Three* of the top ten aircraft operators f lew more compared to August 2018. The operators w ith the highest traff ic grow th w ere Loganair, Air Baltic, Transavia France, Sunexpress and Thomson Fly. Norw egian Air International, Travel Service, Thomas Cook and Condor recorded the highest traff ic decreases. easyJet Europe commenced use of their second operator code EJU at the start of the IATA summer season, resulting in a shift of f lights from the EZY code. Jet2.com saw new aircraft join their f leet. The decrease of f lights for Norw egian Air International IBK is a result of a low er level of aircraft utilisation during the month. *EZY + EJU combined operated +3.1% compared to Aug 2018.

NM Monthly Netw ork Operations Report - Analysis – August 2019 TLP: WHITE Page 5

The highest relative traff ic increases in August 2019 w ere in L’viv, Sarajevo, Dnipro, Beirut and Skopje ACCs. Traff ic increase in Ukraine is partially due to an increase in overflights. High traff ic in the Balkan region and eastern Italy due to increased tourist traff ic to Greece, Turkey and Middle-East combined w ith f low s shifting from more northerly routes.

2. ATFM DELAY AND ATTRIBUTIONS

Total ATFM delays decreased by 4.2% in August 2019i.

En-route ATFM delays decreased by 5.5% and airport ATFM delays increased by 1.2%.

The rolling 12-month trend show s that ATFM delay w as 2.0% higher during the period September 2018 – August 2019 compared to September 2017 – August 2018.

En-route ATC capacity (34.4%), en-route w eather (22.0%) and en-route ATC staff ing (22.0%) w ere the main causes of ATFM delays in August 2019.

These are the top 20 delay generating locations for the reporting month w ith respect to total ATFM delays. Figures are the average daily delays in minutes for the individual locations.

• Convective activity impacted operations strongly in Vienna, Marseille and Karlsruhe ACCs; • High delays due to capacity/staff ing in Marseille, Karlsruhe, Vienna and Budapest ACCs; • High delays at Athens airport despite an overall increase in ATC capacity in both airport and TMA to meet the demand.

EN-ROUTE ATFM DELAY PER DELAY GROUP

En-route ATFM delays accounted for 79.9% of all ATFM delays. Most of this delay w as caused by en-route ATC capacity, en-route w eather and en-route ATC staff ing as explained in detail below . The other causes w ere: En-route capacity; Military exercises in Karlsruhe and Nicosia ACCs; En-route disruptions; Partial closure of IFR ops room on 30 August in Bordeaux ACC; En-route ATC disruptions; Frequency problems in Athens, Warsaw and Bordeaux ACCs.

Budapest and Karlsruhe ACCs acknow ledge at Weekly Summer Coordination meetings that staff ing shortages are responsible for much of the ATFM delays.

Convective activity impacted operations strongly in Vienna, Marseille and Karlsruhe ACCs throughout the month. A total of 147,253 minutes of ATFM delay w ere recorded in Vienna ACC.

Several staff ing issues throughout the month in Marseille ACC generated a total of 244,668 minutes of ATFM delay.

The average daily f lights w ith an en-route ATFM delay of at least 15 minutes decreased from 2,461 f lights/day in August 2018 to 2,325 f lights/day in August 2019, w hich represents 6.7% of all traff ic.

AIRPORT/TMA ATFM DELAY PER LOCATION

AIRPORT/TMA ATFM DELAY PER DELAY GROUPS

Airports accounted for 20.1% of all ATFM delays in August 2019, mainly due to ATC capacity, w eather and airport capacity.

High delays at Athens airport despite an overall increase in ATC Capacity in both Airport and TMA to meet the demand. High demand at London/Gatw ick airport generated delays.

Strong w inds impacted operations at London/Heathrow and London/Gatw ick airports. Thunderstorms generated delays at Frankfurt/Main airport.

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 Off ice for Delay Analysis (CODA) from airlines. Data coverage is 61% of the commercial f lights in the ECAC region for July 2019. ATFM delays reported by airlines may be low er than the NM calculated ATFM delays due to difference in methods: ATFM delays of NM are the (f light) planned “delays”; the airlines report the “actual” experienced ATFM delay on departure. For instance, a f light w ith an ATFM delay may also have a handling delay absorbed w ithin the ATFM delay. In the event of a long delay an example being during ATC industrial action a f light may keep its original schedule, how ever w hen it’s f light plan is submitted for example a day later any ATFM delay allocated may be low er or zero, in this case airline reported delay w ill exceed NM reported ATFM delay.

Based on airline data, the average departure delay per f light from ‘All-Causes’ w as 17.49 minutes per f light, a 17% decrease in comparison to July 2018 w here the average delay w as 21.03 mins/f light. Primary delays counted for 53% or 9.24 min/f lt, w ith reactionary delays representing the smaller remaining share of 47% at 8.25 min/f lt.

Further analysis of the past 12 months show s that the monthly average ‘All-Causes’ en-route ATFM delay w as at 3.04 minutes per f light in July 2019. In July 2019, ATC capacity delays occurred in Vienna, Zagreb and Barcelona ACCs. ATC staff ing delays w ere recorded in Marseille, Karlsruhe and Budapest ACCs, w ith w eather (convective activity) also affecting Marseille and Vienna ACCs.

The percentage of f lights delayed greater than 15 minutes from ‘All-Causes’ decreased, by 4.7 percentage points to 31.6% w hen compared to the same period last year. ‘All-Causes ’ delays exceeding 30 minutes fell by 3.8% points to 17.2% of f lights. 9.6% of f lights in July 2019 experienced an ATFM delay exceeding 15 minutes w ith 3.7% of f lights having an ATFM delay exceeding 30 minutes.

7. ATFM SLOT ADHERENCE

The percentage of early departures for August 2019 is 4.2% of regulated f lights, w hich is the same as July 2019. The percentage of late departures for August 2019 is 3.5% of regulated f lights, w hich is a decrease of 0.8 percentage points compared to August 2018.

The chart below show s the airports that have more than 300 regulated f lights during the month w ith their average daily number and proportion of regulated f lights that departed outside of the Slot Tolerance Window (STW). Any airport above the red line is non-compliant w ith the threshold (20%). Those airports w ith a number of departures outside the slot tolerance w indow can reduce netw ork predictability.

9. NM ADDED VALUE FLIGHTS WITH DELAY > 30’ The number of f lights w ith more than 30 minutes of ATFM delay decreased by 11.3% betw een August 2018 and August 2019. In August 2019, 77.4% of f lights w ith more than 30 minutes of ATFM delay w ere en-route and 22.6% w ere airport. An average 168 f lights per day had their delay reduced to less than 30 minutes by NM.

REROUTING PROPOSAL DIRECT DELAY SAVINGS On average 10 RRPs/day w ere executed saving 725 min/day, accounting for 0.6% of ATFM delays. This graph show s the actual daily averages for the previous 13 months’ periodiv.
