Modern aircraft incorporate a number of hydraulic systems. Each exists either to provide redundancy (or a fallback system) to a particular section of the aircraft such as flying controls, or provides a unique service to a sub-system, such as landing gear. One of these systems might be a dedicated emergency system, and would provide alternative fluid power to essential controls in the event of the loss of the normal system supply. It is into such a system that a Ram Air Turbine (RAT) would be installed. Ram Air Turbines have already been used in service and are responsible for the recovery of a number of civil and military A/C from a potential catastrophic situation. The application of reliability engineering to an emergency system such as a Ram Air Turbine, shows that dormancy plays a major effective role on the resultant failure probabilities.
