Abstract: A new Operator display subsystem is being incorporated as part of the next generation United States Navy (USN) helicopter avionics system to be integrated into the Multi-Mission Helicopter (MMH) which will replace both the SH-60B and the SH- 60F in 2001. This subsystem exploits state-of-the-art technology for the display hardware, the display driver hardware, information presentation methodologies, and software architecture. The technologies to be base technologies have evolved during the development period and the solution has been modified to include current elements including high resolution AMLCD color displays that are sunlight readable, highly reliable, and significantly lighter that CRT technology, as well as Reduced Instruction Set Computer (RISC) based high-performance display generators that have only recently become feasible to implement in a military aircraft. This paper describes the overall subsystem architecture, some detail on the individual elements along with supporting rationale, the manner in which the display subsystem provides the necessary tools to significantly enhance the performance of the weapon system through the vital Operator-System Interface. Also addressed is a summary of the evolution of design leading to the current approach to MMH Operator displays and display processing as well as the growth path that the MMH display subsystem will most likely follow as additional technology evolution occurs.!2
