Ostend Airport RUNWAY PERFORMANCE REPORT 2020
member of FABEC / www.skeyes.be EXECUTIVE SUMMARY
Air Traffic Management (ATM) Performance is Looking at the distribution of traffic per runway, it driven by four Key Performance Areas (KPAs): safety, can be seen that 2020 follows the trends of 2017 and capacity, environment and cost-efficiency. This 2019, with runway 26 being preferentially used. 2018 report focuses on skeyes’ operations at Ostend- was a year with more north-easterly winds recorded Bruges International Airport (International Civil at all Belgian airports, implying a more frequent use Aviation Organization (ICAO) code EBOS). Its aim is of runway 08. In 2020, winds blew predominantly to provide our main stakeholders with traffic figures from the South-West, with an exception for the for 2020 and relevant data on the performance of our months of April and May where more easterly winds operations at Ostend Airport, namely on three of the were registered and the use of runway 26 dropped to four KPA’s: safety, capacity and environment. around 40% (being on average at 71% for the whole year). Traffic Safety The year 2020 will be remembered for the breakout of the coronavirus COVID-19 pandemic, which Three topics are presented in this report: greatly impacted aviation. Low records of traffic were missed approaches, runway incidents, such registered in Ostend-Bruges International Airport, as runway incursions, and improvements and with an average drop of 25% in comparison with 2019. recommendations. Regarding the first matter, Furthermore, in April 2020, during the COVID-19 first Ostend Airport registered 11 missed approaches wave, a reduction in flights of 76% was seen in the overall in 2020, ten on runway 26 and one on runway airport. 08. Weather conditions and unstable approaches are the main reasons, accounting for 82% of the missed Traffic flying by Visual Flight Rules (VFR) accounts approaches at Ostend Airport. for approximately two-thirds (66%) of the traffic in Ostend, and although restricted during the first There was one runway incursion in 2020, categorised months of the pandemic, this flight rule category as severity ‘C’ (significant incident). There were four saw a positive trend in the summer months (July more runway incidents – a runway excursion, two through September), with up to +21% of the previous taxiway excursions and a taxiway incursion – none of year’s traffic in July. Throughout the hours of the day, which happened with the involvement of skeyes. VFR movements had similar averages than previous years during the morning (06:00-09:00 local time), As in all Belgian airports where skeyes provides air and the same trend, with less movements, during traffic services, a Local Runway Safety Team (LRST) the rest of the day. Traffic flying by Instrument Flight is in place in Ostend, involving pilots, air traffic Rules (IFR) decreased more severely, both in average controllers, the airport and safety managers. During and in absolute numbers, and a peak is hardly visible LRST meetings, safety issues are discussed and during the day. investigations are shared among all parties so that all may benefit from the lessons learnt.
II Capacity and Punctuality Environment
At Ostend Airport, the declared IFR & medium In 2020, the Preferential Runway System (PRS) in weight VFR capacity was exceeded on eight days place at night at Ostend Airport was complied with during the year. However, at the peak hour of by 67% of the departures and arrivals. Even in the those days, mostly VFR flights - around 80% - were months of April and May, where the wind patterns recorded. On average in 2020, the traffic at peak changed to mostly North-East, the PRS was followed hour was 20.8 movements below the declared IFR & by respectively 66% and 61% of the movements. medium weight VFR capacity.
While there are no annual targets with regard to Air Traffic Flow Management (ATFM) arrival delay for Ostend Airport, skeyes registers the arrival ATFM delays, as part of a continuous monitoring of the Air Navigation Service Provider’s (ANSP) performance. In 2020, as in 2019, no ATFM arrival delay has been recorded in Ostend Airport. From a passenger or airport perspective however, delays are observed more frequently than this. In fact, every departure or arrival can be affected by ATFM regulations placed in other parts of the Belgian airspace, by other countries in whose airspaces the aircraft flies through, or by the airport of arrival, possibly also in another country. In 2020, flights landing in Ostend Airport experienced a total of 1,791 minutes of ATFM delay, of which 13% were due to skeyes en-route regulations. Flights taking-off from Ostend totalled 1,498 minutes of ATFM delay: 10% attributable to skeyes, and the remaining 90% due to regulations placed by other ANSPs. Overall, there was a decrease in ATFM delay at Ostend Airport of 86% compared to 2019 figures.

In 2020 is er, net als in 2019, geen ATFM-vertraging bij aankomst vastgesteld op de luchthaven van Oostende. Vanuit het oogpunt van de passagier of de luchthaven worden echter vaker vertragingen waargenomen. In feite kan elk vertrek of elke aankomst worden getroffen door ATFM-regulering in andere delen van het Belgische luchtruim, in het luchtruim van andere landen dat het vliegtuig doorkruist, of op de luchthaven van aankomst, eventueel ook in een ander land. In 2020 hebben aankomende vluchten op de luchthaven van Oostende in totaal 1.791 minuten ATFM-vertraging opgelopen, waarvan 13% te wijten was aan en-routeregulering door skeyes. Vertrekkende vluchten uit Oostende telden in totaal 1.498 minuten ATFM-vertraging: 10% daarvan was te wijten aan skeyes en de overige 90% aan regulering door andere ANSP’s. Over het algemeen beschouwd liep de ATFM-vertraging op de luchthaven van Oostende met 86% terug in vergelijking met de cijfers van 2019.

1. TRAFFIC
In this chapter, the traffic at Ostend Airport is presented, as recorded by the Airport Movement System (AMS) developed by skeyes. The AMS records the movements at an aerodrome and within its Control Zone (CTR) which are defined as an aircraft either crossing the CTR, landing or taking off at the aerodrome.
The figures presented throughout the report consider a movement as a take-off or landing of all traffic. As this report considers runway performance, movements such as crossings of CTRs are not considered. As such1: y one take-off = one movement y one landing = one movement y one touch-and-go = two movements.
When time is mentioned, movements are given in local time, throughout the report.

Traffic / 9 10 / Traffic 2. SAFETY
This section is divided in three topics: missed approaches, runway incidents, such as runway incursions, and improvements and recommendations.
The missed approaches covered in the following chapter are based on internal logging made by the Air Traffic Control Officers (ATCOs). As such, the quality and accuracy of the available information is commensurate with the level of reporting. These logs of missed approaches are not considered as safety occurrences. They are an operational solution allowing to maintain safety margins when the approach cannot be continued for a safe landing. At the same time, particularly during peak hours at busy airports, they also increase the traffic complexity and the residual safety risk. It can be argued that missed approaches are a hybrid leading indicator, and that by analysing the reasons leading to this type of procedure, one can examine if there are any systemic deficiencies in a technical equipment, in a procedure or in manner in which ATCOs and/or pilots apply these procedures.
The runway incursions are a lagging runway safety indicator. The runway incidents and other noteworthy incidents are safety occurrences. These are subject to a risk classification using the Risk Analysis Tool (RAT) methodology to assess the contribution that skeyes had in the chain of events (in accordance with EU Reg 376/2014 and EU Reg 2019/317). The following definitions apply for the severity classification (as per EASA Acceptable Means of Compliance (AMC)). This classification scheme is applicable for the later mentioned operational occurrences.
Severity Classification Description A – Serious incident An incident involving circumstances indicating that an accident nearly occurred. An incident associated with the operation of an aircraft, in which the safety of the aircraft may have been compromised, having led to a near collision between aircraft, B – Major incident with ground or obstacles (i.e. safety margins were not respected; in this case, not as a result of an ATC instruction). An incident involving circumstances indicating that an accident, or a serious or major C – Significant incident incident could have occurred if the risk had not been managed within the safety margins, or if another aircraft had been in the vicinity. Insufficient information was available to determine the severity, or inconclusive D – Not determined or conflicting evidence precluded such determination (RAT RF < 70 %). E – No safety effect An incident which has no safety effect. Safety occurrences are discussed in the Local Runway Safety Team (LRST), which is a meet- N – No ATM Ground ing among the airport’s main stakeholders where skeyes and other partners discuss safety contribution (or no related events, with a focus on actions to be taken.

3. CAPACITY & PUNCTUALITY
This chapter addresses the airport’s capacity and punctuality. In a first part, the declared capacities for runways 08 and 26 are provided, as calculated in 2018, and a view is given on the use of the capacity by looking at the number of movements during peak hours in the busiest month of 2020.
In the second section, the punctuality (arrival delay) at Ostend aiprort is studied. The delay is also analysed from the airport’s point of view, i.e. considering the impact caused by regulations not only at Ostend Airport, but also in the Belgian en-route airspace and by other Air Navigation Service Providers.

4 Note that in chapter 1, movements are defined by the AMS and the BCAA criteria. In this chapter, the Network Manager (EUROCONTROL) is taken as source for traffic numbers and only accounts Capacity & Punctuality / 23 for flights with a registered flight plan. The delay in 2017 happened due to weather. All of the delay, 383 minutes, was accumulated on the 11th of December 2017, as the runway was unavailable due to snow from 10:20 until 17:40 local time.
A zero rate regulation was put in place on Novem- ber 28th, 2018 when the airport experienced a power failure, leaving the runway lighting aids unservicea- ble. The regulation was put in place between 08:10 and 10:00 local time under the reason E-Equipment (non-ATC). This affected only one flight and caused the 47 minutes of delay.
In 2019, there was a delay of 45 minutes due to one regulation at the airport. This regulation was on departure traffic and the delay is therefore not an arrival delay. The regulation was put in place on March 21st, 2019 between 07:15 and 09:15 local time under the reason I-Industrial Action (ATC) (NOTAMs A0931/19 and A0932/19). This affected one flight and caused the total delay of 45 minutes in 2019.
No regulations, and therefore no ATFM delay, were placed in Ostend Airport in 2020.

4. ENVIRONMENT
As a majority of airports, Ostend Airport is located near populated areas. It is therefore all the more important to consider noise and its reduction, as far as possible, in the vicinity of the airport. One of the ways to do so is to put in place a preferential runway system, a decision taken by the BCAA, which prioritises a runway use above the other, given that some conditions, mainly weather driven, are met.
This chapter will present, in the first part, the compliance to the preferential runway system in Ostend, and, in a second part, it will give an overview of wind speed and direction, as wind is a major factor in the choice of runway use. Preferential Runway System
