Brochure: NARSIM – One simulator for ATC Radar and Tower simulations

The air traffic control environment requires frequent updates and modifications in order to comply with the newest regulations, address capacity and operational issues or improve the operational performance. Requirements for the new or modified procedures and systems can be tested and validated with a real time ATC simulator. This minimizes the risk during the implementation and increases the predictability of the actual operational performance.

NLR’s NARSIM facility is a real-time, human in the loop (HITL) Air Traffic Control (ATC) simulator capable of simulating the full working environment and working conditions of air traffic controllers in detail. As such, it provides a platform for training, validation and conducting research in a controlled environment on all aspects of air traffic control and the air traffic controller.

NARSIM is developed in-house by NLR and therefore has a high degree in configurability, flexibility,
interoperability and adaptability. NARSIM simulates air traffic control platforms of all major manufacturers
(also concurrently in one simulation). Connections to a range of external systems, such as flight simulators,
are also supported.

Booklet: R&D More electric and hydrogen-electric powered aerospace

Hydrogen as a fuel is considered to be an important route towards future sustainable aviation. For aviation
applications, hydrogen presents several key advantages: it allows for the elimination of carbon emissions in
flight and along the entire life cycle. Its usage in fuel cells allows eliminating NOx and particles. When burnt
in a turbine engine, very low particle emissions can be expected, as well as reduced NOx emissions, provided that the combustion system is optimised. However, water vapour emissions need to be carefully managed.
