Safety and Human performance

NLR can support the development and optimisation of human machine interfaces (HMIs) for various aerospace applications, including flight instruments, dynamic traffic signs, air traffic controller support tools, and virtual- or augmented reality based training tools. Whether it's designing a new HMI, evaluating an existing one, or updating and extending current systems, NLR can help integrate different data sources into one coherent and efficient tool. This enhances operator performance and safety.

NLR can help assess the workload of aerospace operators, including air traffic controllers, pilots, and other professionals, providing valuable insights into operator overload or underload. By combining objective and subjective data, we can accurately express workload levels, enabling informed decisions to optimise operator performance and safety.

Operators of complex systems face the challenge of processing multiple sources of information in the right order. NLR can help you gain insight into the factors affecting your operators' performance, such as distraction, attention, and strategy application. We can also help you understand how sub-optimal Human Machine Interfaces (HMIs) may lead to high visual workload, and how new tools, interfaces, or procedures may impact mental workload, fatigue, and situational awareness, ultimately affecting their ability to make informed decisions.

Ensuring the safety of aviation operations is a complex task that requires careful consideration of various factors. NLR can help you assess the impact of changes in operations or future Air Traffic Management (ATM) concepts on safety, as well as provide evidence that safety will not be compromised even when regulatory compliance is not feasible.

Analysing flight data is a crucial aspect of safety assurance, and many operators closely monitor their daily flight operations to identify any exceedances and mitigate potential risks. While commercial off-the-shelf software is available to support flight data monitoring (FDM), it often falls short when it comes to addressing complex flight operational issues. That's where NLR comes in - our team provides additional analysis capabilities and operational expertise to help you gain deeper insights into your safety performance and better understand the risks associated with your flight operations.

Taking your oversight system to the next level requires a shift from compliance-based to performance-based safety oversight. This transition enables you to focus on safety performance and risks, rather than just compliance with regulations. A key element in performance based oversight is having up-to-date knowledge of the safety performance of individual aviation organisations as well as at state level.

The introduction of new technologies such as 4D trajectories, pilot controller datalink, and enhanced mode-s is transforming the air traffic management landscape. As these changes unfold, it's essential to ensure that air traffic controllers (ATCos) are optimally supported in their critical work. NLR's expertise in Human Machine Interface (HMI) design can help organisations navigate these changes. Our experienced designers have  deep understanding of operational air traffic management and can help address key questions such as how to integrate new information without overloading ATCos, how to design intuitive HMIs and how to generate user buy-in for new systems. With our structured and proven approach, we can help you create HMIs that enhance controller performance, reduce workload, and increase overall efficiency.

Runway end safety areas (RESAs) are designed to protect aircraft and occupants from runway overrun or undershoot events, which are a significant cause of aircraft accidents and serious incidents during take-off and landing. The recommended dimensions for RESAs are defined by regulatory bodies such as ICAO, FAA, and EASA. However, many airports face challenges in implementing these recommendations due to limited land availability to accommodate standard RESA dimensions and existing aerodromes that were constructed before RESA requirements were introduced.

Many airports struggle to identify the actual risk levels and the appropriate mitigations against the rise of runway incursion. Runway incursions involve the incorrect presence of an aircraft, vehicle or person on the protected area of a surface designated for the landing and take-off of aircraft. Runway incursions have sometimes led to serious accidents with significant loss of life. Although they are not a new problem, with increasing air traffic, runway incursions have been on the rise. There are many causes related to runway incursions making it hard to quickly identify the risk levels and define mitigating measures.
