THE EFFECT OF SYSTEM OPERATION DURATION ON FAILURE RATE: A STUDY OF STRATEGIC AIRLIFT AIRCRAFT

CHRISTOPHER CAMPBELL SHAW, University of Nebraska - Lincoln

Abstract

The level of stress experienced during system turn-on was hypothesized to be greater than the stress level of steady-state operation. This fixed plus variable approach to the cause of failure permitted the isolation of the steady-state stress. Some 85,000 C-5 and 840,000 C-141 strategic airlift aircraft missions were analyzed using flight length as the independent variable. A one hour temporal adjustment of flight length was made for the takeoff and landing phases of flight. The equation Y = a + b(x-1)/X provided and x of 0.99 for both aircraft. Thus, the average failure rate decreases as system operation duration increases.
