Do you need
What we have

When developing or modifying air traffic control, airport, or airline operations and procedures, good practice requires that these are introduced only after the safety of the designed or changed procedures has been assessed as compliant with appropriate safety criteria.

This safety assurance is often formalized within the organisation’s Safety Management System procedures and sometimes required within European regulations.  For ANSPs for example, this is formulated in the common requirements EU 2011/1035, which will be replaced by the new regulations EU 2017-373, in force from 2020 onwards. These new regulations emphasize the argument, instead of the process.

You may want to have your operations and procedures assessed to be compliant with appropriate safety criteria.

NLRs Safety Institute provides support in the development of safety cases, by supplying underlying safety data, expert judgment or process organisation advice, and we may take responsibility to develop a complete safety case for you. Our quality is to combine the pure operational, local view with the expertise of safety methods, processes and regulations.

Our safety assessment methods and models can be applied to various types of air transport safety studies, for instance concerning collision risk, controlled flight into terrain and wake vortex risk.

NLRs Safety Institute has been awarded many contracts by Air Navigation Service Providers and airports to carry out safety assessments to support the implementation of new and changed operations. Some examples are:

  • For LVNL (the Dutch ANSP) we carried out safety assessments of operations at Amsterdam Airport Schiphol, like parallel approaches and departures, converging approaches, missed approaches, crossing active runways, introduction of a new runway, building a second air traffic tower
  • For ATNS (the ANSP of South Africa) we carry out safety assessments for the introduction of RVSM in Africa
  • Evaluations of the accuracy of GPS-based non-precision approaches and transitions were carried out under contract by the Dutch CAA and LVNL
  • Several safety assessments have been and are being performed for Skyguide (the Swiss ANSP), including a determination of collision risk related to P-RNAV transitions and approaches
  • We support EUROCONTROL in several studies to establish and validate appropriate regulation for the application of RNAV in terminal airspace. Other studies focus on assisting EUROCONTROL in the development of safety arguments to support implementation of RNAV operations at European airports.
