This report describes a feasibility study for the characterization of runway roughness. Two methods have been examined. This document presents a full description of the developed method, and features a description of how the method can be used by any airport to self-assess their characteristic surface roughness (or ride quality). The method does not require the use of specific aircraft simulation software.
