How does air traffic operate?

At the crossroads, there are always traffic lights. Vehicles and pedestrians all respect the rules of ' red lights stop, green lights ', so you can avoid chaos and traffic accidents. Air lines also adhere to such principles .

Traffic in the sky is unexpected

Sometimes, when night falls, looking up at the sky, we can discover that the horizon has red, blue and white spots slowly flying by. It is an aviation lamp on a three y machine . It also works to avoid traffic accidents in the air.

Although the sky is extremely large, the flight speed of the aircraft is very fast, so there is still a risk of collisions. In order to avoid airborne accidents, in addition to certain air routes regulated for civil aircraft on regular routes, pilots must also pay close attention to the following front, right, left, above to avoid other planes. In order for the pilot to look around and constantly grasp the flight path of other planes that are traveling with them, when the plane flies in the night, it is necessary to light up three aviation lights on the left, right and one. lights in the tail section. Observing at the pilot's position, the red light is always on the left wing, the green light is always on the right wing and the white light is on the tail. Three lights can continuously light or blink.

After the aircraft turned on aviation lights at night, the pilots' observations were much more favorable. If the pilot sees an aircraft at the same height as him, but only sees two red and green lights, then the opponent is facing opposite to him, at risk of crashing, needing measures to avoid. If only one light is seen, then the opponent is on the left or right side. If you see all three lights at the same time, the opponent is flying above or below you. These two situations are not dangerous, pilots can completely rest assured to drive.

However, the speed of modern aircraft is very large, just relying on the indicator light is not enough. In the case of bad weather, cloudy and fog, how to do it? There is now a type of device called an aircraft access indicator device that can help pilots detect aircraft near them. This device is fitted with an indicator light, and the radar on the aircraft constantly transmits radio waves around, when another plane flies near the radar, it bounces back, causing the indicator light to light up. . From different indicator lights can reflect the direction of flight and the relative distance of the aircraft flying near to me.
