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.
