The Paris Air Show is in full swing, with aircraft makers Boeing and Airbus engaged in a fierce competition to score orders for their newest planes. Most of those planes feature state-of-the art technology, making it possible to predict everything from part failures to turbulent weather in real-time.
An engine alone, for example, is likely to have as many as 5000 elements monitored every second.
"It's not Google big data, but it's a lot of data," says Bill Baumgarten, Business Development Manager at UTC Aerospace Systems, one of the major suppliers of high-tech sensors to the industry. Among the capabilities UTC sensors provide: monitoring the temperature of an engine part to flag even a five-degree variation from normal, or sensing a change from flight plan.
"Maybe [the plane] is burning more fuel than it should because of wind conditions, maybe the pilot has deviated from the flight plan for no intended reason, or maybe something happened on the aircraft, a part is broken or a system is malfunctioning,". That data is monitored by analysts on the ground, who can immediately respond.
While safety and security are the highest priorities, all of this also saves money and time for airlines. Southwest Airlines is among those adopting Boeing’s Airplane Health Management, which uses real-time data monitoring to reduce fuel consumption and boost efficiency.
Then, there's weather. Southwest and UPS actually send data to the National Weather Service, augmenting the government agency’s weather balloons with more frequent and precise data on current conditions like humidity, and the potential for icing or turbulence. More accurate forecasts mean better scheduling and fewer flight disruptions. Delays are responsible for $8 billion in losses for the airline industry, according to Bloomberg.
In the future, airlines plan to use the data analysis happening at headquarters to update pilots in real-time. Southwest, for instance, imagines a day in the near future when pilots have WiFi connections to the ground, using sensor data in both directions to optimize fuel consumption and adjust flight paths instantaneously. Pilots’ Electronic Flight Bags can be updated with new data constantly.
Modern plane sensors are generating so much data — terabytes worth in some cases — that airlines have to be ready to make use of it all. “You’re going to have to have the tools to mine it, otherwise it’s just a bunch of data you’re not tapping into,” Leonard says.
