Why aircraft electronics are becoming harder to cool More capable avionics, onboard computing and electrification are putting additional heat aboard aircraft and changing how engineers approach cooling. By Samantha McGrail Putting more computing power aboard an aircraft creates another engineering problem: the electronics have to get rid of the heat they produce. That challenge grows as vehicles add more capable avionics,...Read More
