The roadmap for Aviation (Figure III-D-1) portrays the Army's use of Technology Demonstrations (TDs) and Advanced Technology Demonstrations (ATDs) to support the development of its future aviation systems, and dual use technology for the nation's rotorcraft industry. The aviation S/SU/ACs are shown at the top of the figure. The lower half of the figure shows the substantial block of aviation technology demonstrations that support the S/SU/ACs and provide the opportunity for technology upgrades of fielded systems. These demonstrations are designed to establish a "Proof-of-principle," i.e., to serve as a test bed, validate feasibility, and reduce cost and risk for entering engineering and manufacturing development (EMD).

The following subsections provide descriptions of the Aviation demonstrations categorized on the roadmap as Mission Equipment, Advanced Platforms, Propulsion, and Logistics/ Maintenance.

a. Mission Equipment

Rotorcraft Pilot's Associate (RPA) Advanced Technology Demonstration (ATD) (93-99). The primary thrust of the Aviation S&T mission equipment area is the RPA ATD. The objective of this program is to establish revolutionary improvements in combat helicopter mission effectiveness through the application of artificial intelligence for cognitive decision aiding and the integration of advanced pilotage sensors, target acquisition, armament and fire control, communications, cockpit controls and displays, navigation, survivability, and flight control technologies. Next generation mission equipment technologies will be integrated with high speed data fusion processing and cognitive decision aiding expert systems to achieve maximum effectiveness and survivability for our combat helicopter forces.

This increased system effectiveness will enable Army Aviation to be more responsive to battle commanders at all levels. RPA will expand aviation's freedom of operation, improve response time for quick reaction and mission redirect events, increase the precision strike capability for high value/short dwell-time targets, and increase day/night, all weather operational capability. RPA will contribute greatly to the pilot's ability to "see and assimilate the battlefield" in all conditions; to rapidly collect, synthesize, and disseminate battlefield information; and to take immediate and effective actions. These developments will enable the full use of the crew's perceptual, judgmental, and creative skills to capitalize on their own strengths and to exploit the adversary's weaknesses.

The Defense Simulation Internet (DSI), through the Army's Battlefield Distributed Simulation--Developmental (BDS-D) program capabilities, will be utilized in the RPA program to perform Measures of Performance (MOPs) validation. The RPA ATD will achieve the following quantitative MOPs relative to Comanche-like performance during 24-hour, all weather battlefield conditions: 30 to 60 percent reduction in mission losses, 50 to 150 percent increase in targets destroyed, and a 20 to 30 percent reduction in mission timelines.
