What are the arrows on a plane wing?
What are the arrows on a plane wing? The arrows are to tell passengers which way to go, in the event of an emergency or evacuation.
Why are airplane wings teardrop shaped?
Airplanes' wings are curved on top and flatter on the bottom. That shape makes air flow over the top faster than under the bottom. As a result, less air pressure is on top of the wing. This lower pressure makes the wing, and the airplane it's attached to, move up.
Why are there arrows on airplane wings?
They are the overwing exit markings. You can see them in full in the following photo. This is because as already noted in another answer, B737 does not have self inflating slides for its overwing exits and as such, the passengers need some guidance for exiting, to prevent them from going the wrong way.
What are the triangles on airplane wings?
When flight attendants or pilots need to look at the wings, the triangle stickers act like a sign telling them exactly where to look.
What are the pointy things on airplane wings?
Ever wondered what those rods sticking out of the trailing edge of an aircraft wing are? Some might think they are aerials or sensors, but actually, they are a lot simpler than that. These are called static wicks, and they are fundamental to safe flying.
Why are plane wings bent up?
Winging it: The curves at the end of modern airplane wings are all about efficiency. As air flows around a plane's wings, it generates high pressure on the bottom surface and low pressure on the top one, which creates lift.
