The success of an aircraft mission is subject to the fulfillment of some operational requirements before and during each flight. As these requirements depend essentially on the aircraft system components and the mission profile, the effects of failures can be very significant if they are not anticipated. Hence, one should be able to assess the aircraft operational reliability with regard to its missions in order to be able to cope with failures. This paper addresses aircrafts operational reliability modeling to support maintenance planning during the mission achievement. We develop a modeling approach to represent the aircraft system operational state taking into account the mission profile as well as the maintenance facilities available at the flight stop locations involved in the mission. It is illustrated using Stochastic Activity Networks (SANs) formalism, based on an aircraft subsystem.
