Improved Models for Risk Assessment of Runway Safety Areas

View Cover




TRB’s Airport Cooperative Research Program (ACRP) Report 50: Improved Models for Risk Assessment of Runway Safety Areas analyzes aircraft veer-offs, the use of declared distances, the implementation of the Engineered Material Arresting System (EMAS), and the incorporation of a risk approach for consideration of obstacles in or in the vicinity of the runway safety area (RSA).

An interactive risk analysis tool, updated in 2017, quantifies risk and support planning and engineering decisions when determining RSA requirements to meet an acceptable level of safety for various types and sizes of airports. The Runway Safety Area Risk Analysis Version 2.0 (RSARA2) can be downloaded as a zip file. View the installation requirements for more information.

ACRP Report 50 expands on the research presented in ACRP Report 3: Analysis of Aircraft Overruns and Undershoots for Runway Safety Areas. View the Impact on Practice related to this report.
