These triangles serve as indicators for the flight crew when they need to inspect the wings, providing them with the optimal viewing points for the external slats and flaps.
"The tiny hole helps balance the pressure difference between the cabin and the outside air," Henny clarified in a recent video.
They noted that as the aircraft climbs, the external air pressure decreases relative to the stabilized cabin pressure.
