Dispatch Reliability Oriented MMEL Formulation Technology Research

Approved by Civil Aviation Administration of China (CAAC), proposal of Master Minimum Equipment List is prepared by aircraft manufacturers to permit some aircraft equipment or its function is not available under certain conditions. Effective MMEL can balance the safety and profitability of aircraft, which means in premise of safety aircraft will maximize the benefits. Aiming to keep dispatch reliability, MMEL is taken into account in all phases of aircraft design and combined with aircraft safety analysis and evaluation process. In design phase, we will make specific components of aircraft more reliable and safer. At the same time, reasonable operating and maintenance procedures are essential to lay down a high reliability MMEL, form aspect of effect of dispatch reliability on operation.
