Flight delays are a familiar headache for most people who fly on commercial airlines. At a personal level, they are disruptive and costly, but for the airlines the impact is exponentially larger. Minimizing the cost and disruption of maintenance activities is a key focus for these businesses. Rolls-Royce has over 13,000 engines for commercial aircraft in service around the world, and for the past 20 years, it has offered customers comprehensive engine maintenance services that help keep aircraft available and efficient. As the rapidly increasing volume of data coming from many different types of aircraft equipment overtakes the airlines' ability to analyze and take insight from it, Rolls-Royce is using the Microsoft Azure platform to fundamentally transform how it uses data to better serve its customers.
