Red-Yellow-Green Lights On Aeroplanes At Night
When you see a plane flying in the sky on a dark night, you must have seen the small red-yellow-green lights flashing on it. But do you know why these red, green and yellow lights are lit on the plane? They have an important role to play. These lights are known as navigation or position lights. These lights help pilots, air traffic controllers and even other aircraft to know the direction and speed of the plane. So let’s know the complete information about this.
Why is this important?
Every aircraft in the world follows a standard lighting system. Aviation authorities like the FAA and ICAO require these lights so that pilots can judge the distance, direction and speed of the aircraft in the dark. If it does not have these colorful lights, then the aircraft will have to face a lot of problems in the sky.
Why are red and green lights placed on the wings:
The red light is always on the left wing tip, while the green light is on the right wing tip. In fact, it shows the traffic signal on the plane. But it does not signal the plane to stop or move, but it gives information about the direction. With the help of this light, every person, whether he is on the runway, in the control tower or in any other cockpit, can identify the approaching plane with just a glance.
How light helps in direction detection:
This navigation light acts like a compass in the sky. If someone sees both red and green lights at the same time, it means the plane is flying directly towards them. If only the red light is visible, the plane is moving from right to left. If only the green light is visible, the plane is moving from left to right. In addition, there is a bright white tail light that starts to look yellow depending on the weather or angle.
Aeroplanes generally use white strobe lights. These lights flash periodically, making it easier to spot the plane in the dark. Whether the plane is American, Indian or Australian, the lighting rules are the same for all. These lights prevent potential collisions between planes at night, aid in navigation and also alert ground staff.
