Why is there a flash on the plane?

Aircraft exterior lights have different functions and special meanings, and there are certain procedures and requirements in use. Therefore, it is necessary for us to learn how to use these lamps. In addition, due to the different aircraft models and manufacturers, the lighting systems of aircraft are different, but the laws are basically the same. Therefore, we will focus on the general standard external lighting system.

1, red anti-collision light: also known as navigation light, EACON light or beacon, installed in the upper, lower and middle parts of the aircraft, one each. The purpose is to prevent planes from colliding. According to different controllers suitable for this model, the lamp flashes at a certain frequency.

This light was turned on when the plane took off and the engine was running! A plane can fly as long as it moves. )

2. Wing lights: Also called wing lights, two single-beam lights located on both sides of the wing illuminate the leading edge of the wing and the air intake of the engine. Used to check the icing condition.

This kind of lamp should be turned on when there is a possibility of freezing, but it is usually turned on in practical application.

3. Navigation light and beacon light: Navigation light, beacon light, Boeing flight as two switches, Airbus plane together. Navigation lights: left red, right green and tail vertebra white are installed on the wing tip and tail hook respectively. Used to identify the flying object as an airplane and indicate the flying direction. Marker lights are installed on the wing tips on both sides of the horizontal stabilizer to provide illumination for airline signs on the vertical stabilizer.

Airbus has two sets of navigation lights. When the shock strut of the main landing gear is compressed or the flap is extended by more than 15 degrees, its marker light is on.

As long as there are people on the plane, the navigation lights must be turned on.

4. Headlight (Airbus): the nose, this light is installed on the front landing gear, and the two lights are called take-off light and taxi light respectively. When placed in the T.O position, the take-off light and taxi light are on; when placed in the taxi position, only the taxi light is on. This lamp is used for front lighting of taxiways and runways. When the plane taxies, it will be placed in taxiing position, and after entering the runway, it will be placed in T.O position. The plane closed after takeoff. When the nose landing gear is retracted, it automatically closes.

*, taxi light (Boeing aircraft): taxi light, this light is installed on the shock absorber strut of the front landing gear. 1. Used to illuminate the front of the plane when taxiing on the ground.

The plane opens when taxiing and closes immediately after leaving the ground.

5. Landing lights: Landing lights are installed at the roots of the wings on both sides, two on the left and two on the right. Used to illuminate the runway during takeoff and landing. This kind of lamp is very powerful, and it will generate a lot of heat when it is used, so it needs high-speed airflow for cooling. So we can't open it until the ground takes off.

The plane opens before taking off and taxiing, and closes after leaving the ground.

The plane opened in the final approach phase and closed after landing.

6. Runway take-off light: also called turn signal or runway side light. Boeing runway take-off light, Airbus runway turn. Installed on the shock absorber strut of the front landing gear, one on the left and one on the right, respectively, to provide lighting for the two sides in front of the nose. Used for lighting taxiways and runway sideline. Close after take-off. The nose landing gear closes automatically when it is retracted.

Start the engine and turn it on. Another purpose is to signal the ground crew to get ready to slide out at night.

7. Advantages of high brightness white light: Also known as high brightness white light anti-collision lamp and strongpoint. This light is installed in the front and rear of the wing and one in the tailbone. Boeing aircraft is installed in the rear tip and tailbone of the left and right wings, and Airbus aircraft is installed in the front and rear tip and tailbone of the left and right wings, with five tails. The purpose is to prevent planes from colliding. This lamp flashes at a certain frequency with high brightness according to the different controllers adapted to the model.

Note: This light can only be turned on after getting permission to enter the runway! You can turn off this light above FL 100. Turn off this light before landing off the runway! !

Normal aircraft exterior lighting should be used in the following order:

1. After the aircraft turns on the main power switch, the pilot will turn on the navigation light, and turn on the wing light and the marker light as needed;

2. Turn on the red anti-collision light when the plane takes off; (The ground test run should also be started)

3. After the aircraft starts the engine, turn on the turn signal and prepare to slide out;

4. After getting the permission to slide out, turn on the slide light and start sliding;

5, after entering the runway, white anti-collision lights;

6. Turn on the landing light to take off after obtaining the take-off permit;

7. After leaving the ground, turn off the taxi lights and turn signals; (The landing gear can be closed automatically after being retracted)

8. When the altitude rises above 10000 feet, turn off the white flash;

9. Keep at least the red flash and navigation lights on when cruising; Turn on the sign lights and fender lights as required;

10, turn on the white flash when the plane drops below 10000 feet;

1 1. After the landing gear is lowered, turn on the taxi light;

12, turn on the landing light in the final approach phase;

13, after grounding, turn on the turn signal, turn off the floor lamp and turn off the white flash;

14. Turn off the taxi light and red flashing light after taxiing in place;

15. If there is no grounding that night, after the flight maintenance finally turns off the navigation lights, turn off the main power of the plane and leave the plane!
