12 OCTOBER 2018 AIRCRAFT MAINTENANCE TECHNOLOGY INDUSTRY OUTLOOK sense to start [implementation] with the systems causing the most significant problems, and address the issues causing the most significant operational interruptions. A system that causes a flight cancellation is more critical than something that causes a 10-minute delay.” There is a cost savings to doing it this way. Lopatko explains, “If they want to address one particular system, say the APU, it’s one price. If they want to address the full aircraft, it will be another. If they enter a maintenance agreement with Honeywell on these components, there is more we can do in terms of favorable pricing.” Lopatko warns if an airline already collects the data for all components covered by Honeywell’s connected maintenance solution, the best approach is often to go all in at once. He explains, “If you’re interested in just one system, but have this huge file coming off the aircraft with information on all systems, it involves extra work to strip out unnecessary information to focus on just one system. In that situation, I’d recommend that you don’t limit yourself.” Though in most cases an aircraft does not need additional hardware to run the system, there are times when adjustments will be needed. The simplest change is when the aircraft already has sensors, but the data is not being captured or downloaded. In these situations, software changes are necessary to capture and download the data. Sometimes airlines need to add a large-capacity, hard drive data acquisition server to aircraft. “You are still using the same sensors and have the same wiring, but you’re adding more powerful data acquisition and an aircraft data gateway,” he says. If an airline is having trouble with components without sensors, Honeywell offers EdgeNode, which is a small device that combines communication capabilities and storage and can be added to components requiring additional sensors. The EdgeNode will transmit data wirelessly to the aircraft data gateway in flight or after it lands. Honeywell’s connected maintenance system is for any aircraft and all fleets, but Lopatko reports airlines must study the financial feasibility of adding it. “Depending on the type of modifications that are required or the pattern of issues you are going to experience, it may not make economic sense to deploy it on a very small fleet,” he says. “But, if the aircraft are already equipped and no modifications are required, it makes sense to do it, even on a smaller fleet.” "A system that causes a flight cancellation is more critical than something that causes a 10-minute delay." — Roman Lopatko, Honeywell HONEYWELL'S GODIRECT Connected Maintenance app instantly gives maintenance crews a detailed look at an aircraft's vital signs.
