This is the sign that the flight crew is very interested in.

If the seating arrangement has this black triangle symbol , try looking out the window, you will see these stickers corresponding to the airplane wing, 1 in the front and 1 in the back. Do you want to know what the meaning and use of this symbol are? The truth will be quite unexpected.

When the crew (flight attendant or pilot) wants to see the plane wing to check, the triangle symbol will tell them they are at the best point to observe . This way of marking will be particularly useful in winter weather conditions with snow, when you want to observe the slat (small wing plate on the back of the wing but in the front) or flap (shield) in the wing Whether it has snow or not, the crew does not need to look at many locations to get the best view quickly, according to Travel and Leisure.

According to Brightside, in case of suspicion of the inclination of the aircraft wing and the clock does not match the parameters, the pilot must directly check with the eye. But such a case occurs with an extremely rare probability.

Looking closer, that symbol will look like this.(Photo: brightside).

In addition, airline crews like Ryanair may ask passengers to move to a place near the place where there is a triangular symbol on the empty flights, according to pilots.Airplane wings are the center of gravity of the aircraft , so when there are many people sitting near the center of gravity will help the aircraft balance better and thus less fuel consumption.

Another plus point for the position near this triangle is that you will be able to have great photos to 'live virtual'.This is the most beautiful and wide-angle view on the plane if you zoom out. Therefore, when traveling by plane, if you are arranged to sit here, please prepare a camera or phone to have super beautiful photos in this place.
