Airport Cologne/Bonn GmbH assigns investigation concerning operational risks of runway strips with insufficient bearing strength within the scope of veer off accidents

June 2016 | Safety Assessment

EASA’s directive CS-ADR-DSN provides specific requirements concerning the bearing strength of runway strips (CBR value of 15 – 20) in order to minimize the hazard of an aircraft running off the runway during veer off incidents/accidents. Within the scope of the EASA certification at Cologne Bonn Airport (CGN) GfL was assigned by Airport Cologne Bonn GmbH (FKB) to conduct a safety assessment for the entire runway system consisting of two parallel runways and the transversal one. CGN as such is further applicant of our methodology, which is currently also being used at Frankfurt/Main Airport (see news of April 2016). For this purpose detailed soil properties were recorded by third parties being incorporated into the risk assessment model developed by GfL (see news entry March 2016). Besides that, further investigations will be carried out covering the risk of aircraft collisions with subsurface constructions. Overall objective is to provide evidence that safe aircraft operations can be guaranteed even if there are potential guideline deviations.
