To illustrate the concept of predictive maintenance, let us consider a hypothetical example of an aircraft engine. Suppose that the engine has several sensors that measure various parameters, such as temperature, pressure, vibration, and fuel consumption, and transmit the data to a cloud-based platform. The platform uses data science to analyze the data and build a predictive model that can estimate the remaining useful life (RUL) of the engine, which is the time until the engine needs to be replaced or repaired. The platform also uses data science to optimize the maintenance schedule and actions for the engine based on the RUL and other factors, such as the availability of spare parts, the cost of maintenance, and the flight schedule. The platform then sends the maintenance recommendations to the maintenance crew and the pilots, who can act accordingly. For example, if the platform predicts that the engine has a high risk of failure in the next few hours, it can alert the crew and the pilots to land the aircraft as soon as possible and replace the engine. On the other hand, if the platform predicts that the engine has a low risk of failure and a long RUL, it can suggest to postpone the maintenance and extend the flight time.
By using data science to enable predictive maintenance, the aviation industry can achieve significant benefits, such as:
