Saving airspace Holding procedures are defined as racetrack patterns based on a holding fix. PANS-OPS1 prescribes how to design the procedures, considering nominal requirements like constant TAS (True Airspeed) and turn rate. PANS-OPS also prescribes how to determine protection areas needed for obstacle clearance, taking into account heading errors, navigational inaccuracies, pilot reaction time, wind, deviations from the nominal flight path etc. Yet, when obstacles are absent, the same protection area is used for spacing from adjacent airspace, consuming a large part of available airspace. Considering the crowded Dutch airspace, KDC (Knowledge & Development Center of Mainport Schiphol) asked NLR-ATSI whether less conservative design guidelines could be developed.

Getting to Grips with Overrun Risk Runway excursions (events in which an aircraft veers off or overruns the runway during takeoff or landing) are the most common type of accidents reported. Worldwide, in 2009, there were about two runway excursions per week, about half of which are landing overruns.

Safely upgrading nordic towers NLR-ATSI and her Norwegian consultancy partner, AconaCMG, are carrying out safety assessments of ATM services at a number of Norwegian airports - including Hammerfest with the aim of achieving a wider understanding of safety-critical issues and facilitating improved safety management.

New data management system improves air safety NLR supported Norwegian company Avinor develop a data management system to improve reporting and monitoring of airport and airspace incidents.

Wind turbines at Curacao pose no threat Before plans to build two new wind parks off the coast of Curacao could be formalized, the Air Transport Safety Institute (NLR-ATSI) was commissioned to study the potential safety risks these wind parks posed to flight routes at HATO Airport and to determine if the wind turbines would interfere with local air traffic radar. Based on the findings of this comprehensive research, which was jointly conduced by TNO (Netherlands Organization for Applied Scientific Research), the Curacao aviation authorities agreed, on 11 February 2010, to permit the construction of the wind parks.
