Flight Deck Motion System (FDMS): Operating Concepts and System Description

摘要

The Flight Deck Motion System (FDMS) is an active operator guidance system for assisting the shipboard Landing Safety Officer (LSO) when landing helicopters in high seas. New concepts for identifying and tracking quiescent periods' in real time are described, and the FDMS capability and reliability are described. Three operating modes are discussed: a quiescent period indicator for real time guidance, a flight planning mode to assist in decision making, and a flight deck data recorder. The measurement and calculation of ship motion parameters is discussed, and the definition of real time criteria is described.
