AH-64A APACHE HELICOPTER RELIABILITY, AVAILABILITY, MAINTAINABILITY/LOGISTICS RAM/LOG DATA SYSTEM

A U.S. Army-developed Reliability, Availability, Maintainability/Logistics (RAM/Log) data processing system was implemented during the initial AH-64A Apache Research and Development flight test program at McDonnell Douglas Helicopter Company and has continued in operation through the first three years of the Apache Production Program. This RAM/Log data system has provided accurate and timely information required for design and product support improvements throughout its operation on the Apache Helicopter programs. This paper describes the basic RAM/Log data processing system operations and its overall capabilities. In addition, specific Apache Helicopter Program systems applications for Design Improvement and for Fault Detection/Location System (FD/LS) performance verification are discussed. An overall RAM/Log data systems evaluation is presented and conclusions are drawn.
