WHY DO AIRCRAFT HAVE DIFFERENT COLORS OF LIGHTS ? WHAT IS THE PURPOSE OF THESE LIGHTS ?
All planes have a green light on the end of one wing, and a red one on the other. Red and green lights,together with a white light located on the tail, are the plane’s navigation lights.The red light is always on the left wingtip,and the green one is always on the right.These navigation lights are on at all times.
Their main purpose is to signal a plane’s exact position to all other aircraft in the sky.
example :- Since the color is in relation with the direction from which an aircraft can be seen, we can immediately determine the trajectory of any airplanes. Therefore, the following conclusions can be drawn:
👳🏻♂️👉If a green and a red light are seen, this aircraft is facing us, flying toward us:
👳🏻♂️👉If a red light is seen, this aircraft will fly from right to left:
👳🏻♂️👉If a green light is seen, this aircraft will fly from left to right:
👳🏻♂️👉If a white and a red light are seen, this aircraft fly away from right to left:
👳🏻♂️👉If a white and a green light are seen, this aircraft fly away from left to right:
👳🏻♂️👉If a white light is seen, this aircraft is seen from the rear, flying away:
Apart from navigation lights, planes have red rotating beacon lights installed on the upper and lower fuselage. When the red blinking light is on, it’s a warning for the ground crew and other planes that the engines are about to start, and it’s dangerous to come near.But pilots keep them on even after take-off because they increase a plane’s visibility in the sky.
A plane has headlights that help the pilot see the runway during landing and take off. Taxi lights are located on the nose, and they illuminate the runway. Landing lights are under the wings near the fuselage.They’re used for the same purpose, but give the pilot a bit wider angle of view for making turns.During take-off, landing lights are switched off when a plane reaches 10,000 ft altitude. When descending, pilots turn them on again at the same altitude.
The white strobe lights fitted at the wingtips. They’re super bright, and pulsate to make a plane visible from miles away. All those blinking lights make perfect sense.
