Operational requirements for helicopter operations low level in degraded visual environment

摘要

In order to assist the pilot to safely operate helicopters in degraded visual environment (DVE), an integrated system of various technologies that will provide improved situation awareness with minimal interpretation whilst controlling the aircraft appears to be essential. To determine the most effective and affordable solution set to enhance helicopter operations in DVE at low altitudes and to help scope the potential range of solutions, the critical tasks of helicopters with the inherent requirements are to be defined. This paper will provide an overview on the operational environment, today procedures and the resulting general requirements for operating helicopters low level in degraded visual environment.
