An Investigation of Airborne Displays and Controls for Search and Rescue (SAR). Volume III. Avionics Analysis and System Synthesis

摘要

The analysis and synthesis of an avionics system for a search and rescue mission must take into account the constraints imposed by the aircraft along with the requirements imposed by the mission and the avionic equipment available as described in Volume II. For this purpose an estimate of the helicopter size and operational characteristics required for the 1972-1974 SAR missions was made. These characteristics are presented. In the study the crew workload analyses and the system synthesis were cycled through twice, once for a baseline system and once for a revised system. Prior to the start of the second crew workload analysis, the number of crew members was reduced from five to four, necessitating a redistribution of functions among the crew. Furthermore, the results of the first analyses indicated that a detailed investigation of the flight control system was required to define the required modes and associated workloads. (Author)
