ON-BOARD IN-FLIGHT CHECKOUT EVALUATION.
Abstract
The benefits of on-board in-flight checkout (OBIFCO) as a maintenance technique were evaluated using a computer simulation. OBIFCO represents on-line performance monitoring of aircraft subsystems by means of digital data techniques. Tactical fighter and transport operations were evaluated in both wartime and peacetime environments. Typical squadron operations, including mission requirements, scheduled maintenance, and unscheduled maintenance, were represented. OBIFCO characteristics were imposed in the form of early warning of impending failures, reduced diagnosis time, and improved diagnosis reliability. A parametric analysis was performed, considering factors such as schedule interruptions, personnel requirements, and the number of uploaded aircraft. Results indicate that efficiency of squadron operations can be greatly improved by more thorough knowledge of subsystem performance. The model used was SAMSOM II (Support-Availability Multi-Systems Operations Model) developed by the RAND Corporation and modified by IBM. SAMSOM II is a Monte Carlo simulation written in SIMSCRIPT I FOR THE IBM 7044 and 7090/7094 computers. (Author)
