Barrier of Silence NLR-ATSI has identified and quantified the risks that an aircraft could be damaged by the Ecobarrier in various scenarios. Given the outcome of the analysis, the safety study might enable Schiphol to persuade Aviation Authorities to accept installation of the Ecobarrier in order to reduce the perceived noise level for its neighbors; the original starting point for this exercise.

Ground handling taking off In approximately 1 in 5000 turnarounds damage occurs during ground handling. Apart from the safety risk, it globally sets back the aviation industry about 10 billion (!) USD per year.

Hovering safety In its continuous drive to help improve safety, DGLM (Directorate-General for Civil Aviation and Maritime Affairs) requested NLR-ATSI to provide them with relevant information needed to answer the following question: Do risks connected to current and future helicopter operations in the Netherlands necessitate policy changes?

Safety culture down to earth The development of our tool to assess Safety Culture in aviation organisations has moved into the next phase. The tool, meanwhile named Aviation Safety Culture - Inquiry Tool (ASC-IT) has now been validated for airlines, airports and MROs and will be operational in 2009 Q4. With the results database infrastructure, benchmarking capability and a standardized reporting format in place, the full ASC-IT service package will then be ready. Validation of the domain specific survey content for ANSPs, Ground Handling organisations, and government agencies such as CAAs will occur in 2010.

Tilting at the windmills? Wind turbines are one of the most popular renewable energy technologies. However when their intended location is close to an aerodrome, a conflict of interests may occur. Such a situation arose when an energy projects developer (Evelop Ontwikkeling B.V.) in the Netherlands planned to erect 5 large wind turbines near the Ecofactorij industrial estate near Teuge airport (jurisdiction of the City of Apeldoorn). A review of applicable regulations regarding obstacle limitations revealed that building wind turbines at this location is allowed. ICAO notes however, that when high obstacles are located outside the Obstacle Limitation Surfaces, they might cause significant operational restrictions.

Civil use of Unmanned Aircraft Systems The history of Unmanned Aircraft Systems or UAS goes as far back as the Vietnam war. Relatively simple aircraft, so called drones, were launched and flew either in a straight line or in preset patterns, collecting video images. Since then, drones have developed tremendously. Today’s UAS are highly sophisticated systems incorporating digital full duplex data links connecting the aircraft to its (automated) control system which processes control signals and telemetry.
