BY SARAVANAN RAJARAJAN S (SARAN) The aviation industry is well known for being capital-intensive. The acquisition of aircraft itself is cost-intensive, the fleet requires heavy maintenance, and everything about the airline operations – from fuel to airport parking facilities to passengers to staff – all incur heavy expenditure. Clearly, any minute lost while an aircraft is out for maintenance stops it from being a revenue-generating asset. Aviation players face immense pressure arising from aircraft maintenance related to maintaining dispatch reliability, lowering maintenance costs, and enhancing the safety of the craft. MRO alone accounted for 9% of total operational costs for airline operators globally in 2018 . Since airlines are constantly plagued with rising costs, bringing down the cost involved in MROs becomes critical. Adding to this, the issues associated with legacy systems used to operate aircraft systems that do not provide a holistic picture into the health of an aircraft, where data is not updated real-time, and where functions are performed in silos – all this makes for a very challenging scenario even for the most seasoned aviation players. This is why experts are referring to analytics as the “altimeter” of the aviation industry that can help businesses measure the heights they have soared. Using analytics they can know exactly what is happening, why isit happening, and what possible impact any event can have on their business. MRO realities demand a move from descriptive to prescriptive analytics According to a survey by Oliver Wyman, the global fleet of commercial aircraft could generate 98 million terabytes of data per year by 2026 . In-flight recorders, operation systems, and staff all generate vast amount of data. However such data is no good if users cannot access it in a timely manner or are unable to use it to derive meaningful insights. Apart from the data from the Flight Data Recorder, Engine Health Management data or Airplane Health Management data, maintenance related data of the components/ aircraft recorded in their MRO platforms provides another data stream for predictive maintenance – for instance, non-routines, removals, no fault found and minimum equipment list occurrences, operator maintenance program and part reliability. Analysing both the operational data from the sensors and the MRO data with the right statistical tools will be the key to a high accuracy prediction. Three types of analytics can help MROs deal with the problem of unpredictability in the area of maintenance and repair of their fleet – 1.Descriptive and diagnostic analytics: Descriptive and diagnostic analytics helps users analyze information based on past events. They answer questions like “What happened?” Alerts, notifications, and standard reports are some key features of descriptive analytics. 2.Predictive analytics: Predictive analytics is more sophisticated and lets users know why something happened and what is likely to happen next. Using predictive analytics and modelling, users can study emerging trends to predict where they are headed. Effectiveness of predictive maintenance is in its ability to leverage the historical data alongside the live operational data to make predictions. This is purely aided by the latest developments on processing of high volume of dynamic data feeds and analysing with sophisticated statistical tools. 3.Prescriptive analytics: Prescriptive analytics lets users know what will happen in the future as well as the possible impact it could have on the business. It also prescribes the best next actions to take in order to minimize adverse impacts. Applications of analytics in the aviation space: Parts and Components: Analytics come in handy in predicting possible failures, accelerating the process of uncovering root causes to problems, and speeding up incident response time. All this can help MROs pre-emptively replace components. Of particular interest are parameters like MTBF (mean time between failures) and MTTR (mean time to recovery) when it comes to dealing with aircraft parts. Technologies cannot be seen in isolation;for instance, while predicting anitem’s removal through predictive maintenance, it is also expected that the software will also suggest the possible replacement options available to keep the aircraft uptime, as well as the other parts which may also be required during replacement. The confluence of predictive maintenance, AI and big data drives the holistic business benefits to the organization. Operations: Parameters of interest on an operational level include fleet availability, resource utilization, lead times, and so on, which can be used for managing the supply chains efficiently, improving inventory management, optimizing staff schedules, and assigning resources optimally. Aircraft: On the aircraft level, insights into maintenance costs and turnaround time are important in order to increase aircraft uptime and ensure safer flight operations. Six benefits of adopting an analytics-driven operational strategy: 1. Analytics can help aviation players save significantly on costs by allowing them to address failure mechanisms proactively. 2. With the right information, MROs can minimize the risks associated with overstocking or stock outs by planning their inventory wisely. 3. With reduced AOG (aircraft on ground) events, the airworthiness of the aircraft increases. 4. Analytics makes it possible to enhance fleet reliability,ultimately trickling down into reduced delays and cancellations for passengers. 5. It ensures higher safety for passengers by reducing the risk of safety incidents. 6. Analytics helps businesses achieve true collaboration by bringing together different stakeholders onto a single platform allowing them to “talk” to each other in real-time. Analytics is instrumental in ensuring greater airworthiness Historically, MRO hasn’t seen much in the way of IT investments. Dependence on paper or excel sheets is the norm, more often than not and this severely limits the way in which MROs operate, despite having massive amount of data at their disposal. Of the top three areas for savings for airlines, two fall under the ambit of MROs – one, predictive maintenance driven by improved dispatch reliability, and two, delay reduction through an improved turnaround process. Advances in technology like AI, digital twins, and advanced analytics can together help aviation players gauge the levels of the heights they are soaring – and enable them to achieve still greater heights. This involves bringing together ERP systems, workforce management systems, analytics, and
