Three ground controllers

Tower

During the day, there used to be one or two ground controllers in Tower Centre and one in Tower West near runway 18R/36L (Polderbaan). Air Traffic Control the Netherlands (LVNL) has added a third ground traffic controller to the crew at the Central Control Tower, depending on air traffic volumes. This reduces the workload of ground controllers and the likelihood of runway incursions and on-ground safety incidents.

The evaluation of the introduction of a third ground traffic controller showed that it indeed led to a reduction of the ground controller workload and did not introduce unacceptable safety risks.

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 crosswalks have been improved, and broken lights have been replaced. The Schiphol rules are updated and enforced, and the sanctioning time is shortened. The Basic training Safety & Security has been improved and is an eLearning with an annual recurrent training.

The lines of sight for traffic are improved on a few crossings at airside. Together with ground handlers, integral safety campaigns are organised.
This measure consists of multiple underlying actions with their own implementation date. Therefore, no implementation and planning date is mentioned on the website.

12. Follow the Greens

Schiphol and Air Traffic Control the Netherlands (LVNL) are researching the feasibility of a ‘Follow the Greens’ taxiway system. These are a set of sequenced green lights that guides pilots along the assigned taxi route. This visual aid eliminates the need for pilots to consult maps, reduces workload for ground controllers and relieves stress on ground frequencies. It will improve coordination and reduces the likelihood of on-ground safety occurrences and runway incursions.

15. Increase number of aircraft parking positions (by building a new pier)

Schiphol is constructing a new pier with parking positions for both widebody and narrowbody aircraft. The new gates can accommodate 3 widebody and 5 narrowbody aircraft, or 11 narrowbody aircraft. The A-pier is located in the southwestern part of the airport, next to the Kaagbaan (06/24). The new pier increases gate capacity and relieves gate planning. As a result, the pressure on ground operations decreases, reducing the likelihood of ground safety incidents. The completion of the pier is also important to create sufficient capacity that allows Schiphol to renovate or remodel other piers.

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.

ISMS partners jointly investigated an incident in which a towed aircraft collided with the passenger bridge on a stand. Based upon this investigation a system is being developed so that when parking a towed aircraft, it is easier to see exactly where to stop.

The measure was implemented. The correct stopping positions are published in the Airport Community App from May 1st 2023.

However, evaluation showed that this information is not used by the ground handlers and that the intended safety effect is not obtained. It is therefore decided to conduct a renewed study on this measure.

ISMS partners jointly investigated an incident in which an employee was severely injured after being hit by an Ambulift (a so called ‘Bulmor’) vehicle.

After the first investigation results, an awareness campaign was launched for improving the pedestrian safety at airside. A temporary Taskforce defined risk reduction actions to improve pedestrian safety at Airside. These measures include safer routes, improving pedestrian infrastructure and behaviour, and increasing enforcement.

Safer walking routes have been created through the terminal, which means that fewer pedestrians have to cross on airside. The use of these walking routes has been supported by a campaign. There is also more enforcement on pedestrian behaviour, such as the mandatory use of pedestrian paths and yellow dots to cross the road.

In addition, work is being done to improve the pedestrian infrastructure and the behaviour of employees on airside.

The pushback process involves close collaboration between various organizations and operators, each following their own procedures. To help pushback drivers follow the correct pushback procedure according to the instructions given by the Ground Controller, Schiphol, LVNL and Ground Handlers are exploring a new tool called the Pushback Support Tool. This tool will be implemented on a tablet, which will be placed in the pushback truck’s cabin.

The main goal of the Pushback Support Tool is to support pushback drivers in performing their tasks safely and accurately. This is seen as a promising way to reduce risks during the pushback process.

47. Stop bar 24 hours

A stop bar is a row of red lights in the pavement of a runway or taxiway at specific points where airplanes and/or vehicles must stop. It shows pilots and vehicle drivers where they must wait before crossing or entering a runway. While the stop bar is illuminated, airplanes and vehicles must not proceed. If necessary, air traffic control can turn off the stop bar when it is safe to proceed.

In the ‘Stop bar 24 hours’ concept, these lights are used throughout the day and in all weather conditions to protect the runways. An initial analysis by Schiphol and its partners suggests that this measure could be highly effective in reducing the risk of accidents on runways. Therefore, further research is being conducted to assess the feasibility of implementing this measure.

The concept of “One runway, one frequency, one language” means using a single radio frequency and language (English) for all activities related to a runway. This can help increase awareness for everyone involved in operations on and around the runways. It may reduce the chance of incidents caused by misunderstandings between air traffic control, pilots, and drivers. Being aware of activities on and around the runway can make the system safer.

Schiphol and its partners are studying the advantages and disadvantages of implementing this concept at Schiphol Airport. A decision will be made based on the results of the study.

At Schiphol 45% of deviations from taxi clearances happen at the locations Zulu (A26/A27/ A28), A29 and A21/A22. The most common underlying root cause considers the fact that taxiways in different directions can have the same name for flight crew who arrive at a taxiway intersection combined with the complex layout of the taxi tracks at these junctions.

Schiphol and LVNL will therefore rename the taxiways at these locations according to the following design:

5. Converging runway use

A missed approach is a standard procedure. An aircraft can come into conflict with departing air traffic when it must execute a missed approach while a converging departure runway is in use. 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.

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 will use a new intersection at Sierra 1. Because aircraft no longer cross at a ‘high energy point’, the risk of runway incursions will decrease.

The newly built intersection has been taken into use at the beginning of 2025. An evaluation of this measure will be performed later.

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.

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. As per January 1st, 2023 the LTO is effective. The LTO has been updated for 2024. The requirements have been worked out more clearly and it has been ensured that all requirements are measurable.

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.

This measure was evaluated in 2023, which showed that all underlying actions were correctly implemented and effective. No more comparable incidents have taken place since.

51. Reduction of ground vehicle movements from and to buffer positions

The G-buffer is increasingly used for handling aircraft. In the spring of 2024, the remote buffer positions G73, G76 and G79 were renewed. Part of this renewal was the introduction of a fixed connection to the fuel system. This means that tankers no longer have to drive to these buffer positions. This is likely to reduce the risk of on-ground safety occurrences.
