Air Traffic Control the Netherlands (LVNL) has raised the upper limit of the Schiphol Terminal Manoeuvring Area (TMA). The TMA is the airspace controlled above and around the airport by air traffic control. By taking these measures, we will utilise a standard method to enable the desired flight profiles. In this way, we will increase the predictability approaching aircrafts’ flight paths, and reduce the complexity of the airspace.

40. License to operate
Schiphol consulted its partners in order to create together a License to Operate (LTO) for Generic Ground Handling Service Providers at the airport. The LTO defines the minimum safety, quality, and operating standards for the ground handling operation. The content was drafted with the involvement of Ground Handling Service Providers, contributing to the shared goals: a safe and healthy workplace for all employees, reliable and excellent performance and sustainable operations. As a result, a level playing field is achieved and clarity is offered on the minimum quality level for ground handling. Schiphol aims at implementing the LTO per January 1st 2023 and will develop the LTO along the way.

4. Deviations by ground handling staff
ISMS partners have investigated the reasons why ground personnel on platforms and service roads do not always comply with the rules and regulations. This research demonstrates several factors at play. To improve this situation, we have now implemented measures that were feasible at short notice.
Line markings and pedestrian zones are improved, and lights are recovered. The Schiphol rules are updated and enforced, and the sanctioning time is shortened. Integral safety campaigns are launched frequently. The Basic training Safety & Security has been improved and is an eLearning with an annual recurrent training.
Program for improving the visibility on crossings at airside is being executed.
This measure consists of multiple underlying actions with their own implementation date. Therefore, no implementation and planning date is mentioned on the website.Study

16. Completion dual taxiway system
Schiphol is equipped with a circumferential double-lane taxiway system, except for the current Quebec taxiway. Schiphol and its partners will increase operational predictability, uniformity and ground capacity by doubling the Quebec taxiway. This will reduce the likelihood of on-ground safety occurrences. The double taxiway will be integrated in the clockwise and counter-clockwise routing of the Alfa and Bravo taxiways. The duplication of the Quebec taxiway will be implemented in three phases (1A, 1B and 2). Phase 1A is implemented. The new aircraft bridge is in use now. Phase 1B and phase 2 will be combined and executed directly after each other, this improves efficiency in the project management and execution.

27. Last minute runway combination changes and complexity of changes in runway combinations
Runway combination changes that take place at the last minute may cause a disruption to the expected flight handling process, both for pilots and air traffic controllers. Air Traffic Control the Netherlands (LVNL) and Schiphol have developed measures to further reduce the number of last-minute runway changes, and the associated risks, in order to prevent air and ground safety incidents. For instance, we maintain landing runways when an aircraft is in the Terminal Manoeuvring Area (TMA) Schiphol; in addition, we use two departure runways when needed for a more stable traffic flow. We have also developed measures to improve the predictability of runway use and traffic flows using improved planning systems such as Arrival Management and Collaborative Decision Making. The percentage of last-minute runway combination changes is being monitored closely. The Schiphol Airport Operations Centre (APOC) is in use from June 2021 on.

29. Crossing runway 06-24 (Kaagbaan)
When taxiing to or from the Sierra platform, aircraft cross runway 06/24 (Kaagbaan). Schiphol and its partners have researched the ways that this crossing can be made safer to mitigate the risk of possible runway incursions. We also looked at alternative taxi routes to and from the Sierra platform. After research it is decided that aircraft are going to use a new intersection at Sierra 1. Because aircraft do no longer cross at a ‘high energy point’, the risk of runway crossings will decrease.

On 6 September 2019 an aircraft attempted to take off from a taxiway instead of the Zwanenburg Runway. A number of measures to prevent this from occurring again were immediately implemented. For example, the standard night taxi route has been changed and the location has been identified as a hotspot where pilots and air traffic controllers are required to be extra alert. The markings that guide pilots towards the runway have also been made clearer and new lightings at runway entries, Runway Guard Lights, have been implemented. Lastly, awareness programs for flight crew and ground controllers are launched.

The Uniform platform was expanded from 5 to 9 parking spaces by Schiphol and its partners. Three additional parking spaces have been created for wide body aircraft. This reduces bottlenecks in parking spot allocation and relieves gate planning, which thereby reduces the risk of on-ground safety incidents. In addition, aircraft will be serviced at the total of 12 parking spots. That means they will cross the Aalsmeerbaan Runway (18L/36R) less frequently, thereby reducing the risk of runway incursions.

As a result, Schiphol and its partners have already taken a number of further measures, such as tightening up the procedure, to reduce the risks of marshalled towing. The tow drivers are trained and qualified for the new 2021 standard. The manual has been changed with a clear instruction for tow drivers on the operational procedure. We have also reduced the need to marshal towing movements, thus reducing the risk of safety incidents with marshalled tows.

5. Converging runway use
A missed approach is considered a standard procedure. An aircraft can come into conflict with departing air traffic when it has to execute a missed approach and a converging departure runway is being used. Air Traffic Control the Netherlands (LVNL) and its partners have been investigating how they can further increase the safety of this procedure.
Timing appears to be an effective measure to reduce the risk of converging approach and take-off operations. By ensuring there is adequate time between these operations we can further decrease the risk of conflicts occurring.
It was decided to implement timing for all converging runways, taking into account the geometry for each of the converging runway combinations. Air Traffic Control the Netherlands (LVNL) will develop dedicated training for the runway controllers focusing both on conflict prevention and resolution.

8. Navigation technology
The European Union is improving the use of European airspace under the project name ‘Single European Sky ATM Research’, or ‘SESAR’. As part of this project, approaches based on satellite technology (RNAV) are implemented at Schiphol. This allows aircraft to carry out an RNP Approach which involves using three-dimensional GPS navigation on the approach to a runway. As of 7 November 2019, an RNAV approach is possible for four runways at Schiphol. The navigation technology makes flight paths for approaching aircraft more predictable, which will reduce the likelihood of any in-flight safety incidents. A date for evaluation will be planned.
