As the title says, so far I only experienced this with the A350-1000 of Air Caraibes F-HAJP. In the inside and outside view the logo on the inside of the winglet appears and dissapears contantly. Yesterday it was on both sides, now it is only on the right side. I made a video of it: Heads up, I go outside about halfway through the video which might be very loud. Kind regards, Cirrus.
