Cedric Lefebvre, Digital Transformation Leader at Airbus, emphasizes how Skywise enhances production through supplier monitoring, industrial process monitoring, and other portals.

The Power of Connectivity:

The commercial aviation industry is one of the most complex organizations in the world. From ticketing to aircraft maintenance to ATC to airports and catering, all its parts require a different set of sub-structures. In order to function at optimal efficiency, there needs to be a bridge of connectivity between them.

In addition, the International Air Transport Association (IATA) estimates passenger numbers will reach 7.3 billion by 2034. To meet this unceasing demand, airplane manufacturers must find innovative ways of managing and monitoring their ever-expanding and changing fleets. That’s where the Internet of Things comes into play.

The Internet of Things (IoT) is a game-changer in both ground and air operations. Predictions indicate that by 2025, there could be up to 100 billion connected IoT devices, influencing various aspects of daily life. The technologies that enable IoT are not in themselves complicated: the latest version of the internet communications protocol, IPv6, which allows for trillions of nodes (or IP addresses) on the internet and wireless proximity-detecting technologies, such as Bluetooth low energy (BLE) beacons, radio frequency identification tags and near-field communications.

The advent of Aircraft Internet of Things (A-IoT) has unleashed a wave of connectivity, turning aircraft into intelligent, data-driven entities. In the aviation industry, IoT connects and gathers billions of data points, enhancing airplane systems management, providing valuable insights, advancing operations and safety, and improving the overall passenger flight experience.

Imagine an aircraft where every sensor, every component, and every system is interconnected, constantly communicating and sharing data. This is the promise of the IoT in aviation. Sensors embedded throughout the aircraft collect real-time data on various parameters, including engine performance, fuel consumption, and structural health. This wealth of information is transmitted to ground-based systems, enabling continuous monitoring and analysis.

For the airline sector, IoT offers multiple opportunities to improve operational efficiency and offer increased personalisation to passengers. Among airlines that have started experimenting with IoT, there are projects to improve passenger experience, baggage handling, tracking pets in transit, equipment monitoring, and generating fuel efficiencies. Real time location data of aircraft that impact a host of actions ranging from Advertising bill boards to flight information dashboards to deciding on optimized routes.

AI enabled IOT

Also, the IoT value will only come alive if smart machine learning algorithms are able to garner insight from the data collected from the sensors and suggest actions in real time.

A rising trend within this context is the introduction of artificial intelligence (AI) initiatives into the aircraft cabin and at the airport, currently being undertaken by an increasing number of airlines around the world. From personalized offers to chatbots recommending upgrades based on customer profile – AI has the potential to increase airline revenue and customer satisfaction, as well as, allow the industry to operate at optimal cost.

This real-time data stream can be used to:

Optimize flight paths: AI algorithms can analyze weather patterns, airspace restrictions, and fuel consumption to determine the most efficient route for any given journey, saving time and money.

Predictive maintenance: By monitoring sensor data for early signs of wear and tear, airlines can proactively schedule maintenance before components fail, minimizing downtime and ensuring safety.

Enhanced situational awareness: Military aircraft can leverage sensor data to gain a comprehensive picture of the battlefield, improving targeting accuracy and pilot decision-making.

Just for a couple of examples, using big data IoT analytics, airlines can lower fuel consumption (and costs) by up to two percent per year. IoT applications could improve overall fuel cost (not just the consumption) taking into account energy prices, when/where to refuel, optimal flight and taxi paths as well as when/how much to hedge for the fuel.

Practical Examples of AI, Big Data, and IoT Revolutionizing Aviation:

Bombardier’s CSeries jetliner that carries Pratt & Whitney’s Geared Turbo Fan (GTF) engine – an engine that comes with 5000 sensors that generate up to 10 GB of data per second. A single twin engine aircraft with an average of 12 hours flight-time can produce 844 TB of data.

While engines are leading the charge and embracing IoT and data generation, avionics systems are also catching up to this trend quickly. The traditional avionics systems transfer data up to a maximum of 12.5 KB/s whereas Boeing 787 Dreamliners and A350s are using Ethernet-based, next-generation aircraft data networks, called AFDX that allows up to 12.5 MB/s.This makes it quicker and easier to transmit the information from avionics systems to the maintenance teams on the ground about current flying conditions, as well as any faults that have occurred during the flight.

New aircraft models like Dreamliners for instance come pre-designed with IP enabled avionics systems that permit real time data to be transmitted to the cockpit and to operations centers on the ground on flying conditions and discrepancies observed during the flight.

Predictive Maintenance: Lufthansa Airlines uses Pratt & Whitney’s EngineWise system, which analyzes sensor data in real-time to predict engine issues early on and prevent in-flight failures. This has reduced maintenance costs and unplanned downtime.

Dynamic route optimization: United Airlines utilizes GE Aviation’s Predix platform to analyze weather and air traffic data, constantly recalculating flight paths to save fuel and minimize delays. This saved them $350 million in fuel costs during 2019.

Personalized in-flight experiences: Qantas Airlines leverages passenger data to predict individual preferences and deliver tailored entertainment options, food choices, and seat temperature adjustments. This enhances passenger satisfaction and loyalty.

Airlines are recognizing the significance of instant accessibility, interactivity, and personalization in their operations.

The integration of artificial intelligence (AI) into aircraft cabins and airport operations is a rising trend. Air Vistara’s creation of “RADA,” an AI-powered robot, exemplifies this trend. RADA is designed to assist travelers at airports, offering improved customer experiences and on-ground services. By scanning boarding passes and providing real-time information, RADA showcases the potential for AI to increase customer satisfaction and operational efficiency.
