Cologne Bonn Airport (CGN) commissions safety assessment regarding runway strips with insufficient load-bearing capacity

July 2016 | Safety Assessment

The EASA guideline CS-ADR-DSN contains specific requirements regarding the load-bearing capacity (so-called CBR value (California Bearing Ratio) of 15 - 20 of the safety strip surrounding the runway (RWY), which serves to protect aircraft in the event of a veer-off incident. 
As part of the EASA certification of Cologne Bonn Airport (CGN), GfL has now been commissioned by Flughafen Köln Bonn GmbH to conduct safety assessments, which are also carried out in a similar way for Frankfurt/Main Airport (see News from April 2016), for the strips of the entire runway system consisting of the two parallel runways and the crosswind runway. The basis for these assessments is the detailed determination of soil parameters by third parties, which are incorporated into the risk assessment model developed by GfL (see News from March 2016). In addition to the load-bearing capacity, the safety assessment of aircraft collisions with underground structures (e.g. shafts) is also carried out. Based on these key areas of investigation, a final check will be performed to determine whether the safe operation of flight operations is guaranteed despite any deviations from the regulations.
