On the establishment of Class 2 helipad takeoff and landing performance for the BK117 C-2: A comprehensive approach based on limited testing and simulation

Abstract

The Performance Class 2 with Defined Limited Exposure (PC2 DLE) concept, already in use for offshore operations, is applied to an onshore confined area scenario for the BK117 C-2, enabling operations from public interest sites helipads with improved safety. The paper describes the defined takeoff and landing procedures together with the associated performance information, which were established by means of the BK117 numerical performance model validated against the results of a limited flight test program.
