Is there anything particular about the color of aircraft navigation lights?

There are uniform rules all over the world. Aircraft navigation lights are equipped with red lights at the left wing tip, green lights at the right wing tip and white lights at the tail end.

1, these three lights should always be on when sailing to indicate the direction and position of the aircraft. Pilots should judge the course of the plane they see according to the color of the lights they see to avoid collision.

2. Aircraft navigation lights and their distribution are inherited from the shipping industry. According to the shipping industry, ships are equipped with red light on the left chord, green light on the right chord and white light on the mast and stern; Non-motorized boats are equipped with side lights, while wooden sailboats are equipped with only one white light. Therefore, the navigation lights of the aircraft are also stipulated to be left red, right green and white, and other colors cannot be used.

Signal function of navigation lights:

1. Seen in the plane direction, the left wing tip is red, the right wing tip is green and the vertical tail tip is white. In order to increase visibility, some aircraft also install two sets of lights with the same color at the wing tip.

2. During the flight, if the pilot sees that the navigation light of the plane in front is left red, right green and white in the middle, he knows that he is sailing with himself and flying forward. As long as he keeps a certain distance, he will not collide; If you see the left, green, right, red and white in the middle, you know that the plane is flying towards you, so you should take evasive measures immediately to avoid the collision between the two planes.
