Monte Carlo simulation modelling of aircraft dispatch with known faults

Time-Limited Dispatch (TLD) allows usage of redundancy within aircraft engine control systems in order to dispatch aircraft with faults present in these systems for limited periods. Such degraded-redundancy dispatch enables aircraft operators to reduce delays and cancellations of aircraft flights through efficient maintenance scheduling. When TLD is applied certification requirements must be met, which ensure that system failure rates do not exceed specified levels. This paper presents a Monte Carlo simulation approach to obtaining the required system failure rates and outlines advantages of the approach in ensuring certification requirements are met.
