Somebody Amazon’d a sunshade onto a heated A320 window. Guess what happened.
May 2026 Airbus Safety First. Crew bought a sunshade online and put it on the right sliding window. The shade trapped heat. The window heat sensor was already failed, so the system kept heating on bad data.
Window got hot and started distorting. Crew got the alerts, pulled the window CB, and diverted. On final the right window cracked.
Inner ply is stretched acrylic. It shrank and showed the interlayer. Outer ply held. They landed.
Same article warns about suction-cup tablet holders. Same heat trap, and they can fall off in turbulence.
Use the sun visors that already sit in the cockpit. If you need a tablet, mount it on the frame, not on the window.
