Abstract

An application for a head-down navigation display is developed to support the flight crew during near-ground operations. Two reference helicopter mission types are defined for a closer evaluation of the developed display applications in a flight simulator. These are an approach to a landing platform of an offshore windfarm on the one hand, and helicopter emergency medical services (HEMS) in high mountains on the other hand.

Ground based LiDAR (Laser Detection and Ranging technique) wind and turbulence measurements are used to derive a representative database, which will be used for the reference scenarios in the flight simulator trials. Additionally, a feasibility study on the usage of ground-based wind and turbulence measurements at helicopter landing sites (e.g. offshore platforms) for a real-time display in the helicopter cockpit is carried out.

From a comparison of metrological capabilities and the operational needs of the helicopter missions, a concept for the arrangement and configuration of the measurement sensors for their operational use and for the implementation of the derived data into the display application is defined.
