How does the daily cleaning work at the airport take place?

A lot of work needs to be done so that plane pilots can safely take off and land everyday.

Every year, about 360000 flights take place at Singapore's Changi Airport.

So it is very important to keep the runway clean without problems. One of the biggest possible risk of accidents for airplanes coming from stray birds inside the runway - because just one bird sucked into the engine can lead to catastrophic accident. In fact, there were many times the flights were delayed only because the runway was not "cleaned up" for the plane to land.

In Singapore, the solution to this problem lies in the car to ensure the safety of the runway, equipped with a set of speakers capable of emitting loud sounds to chase birds.

The car is equipped with a set of speakers capable of emitting loud sounds to chase birds.

Marcus is an employee at Changi Airport. He said that every day he had to get up from 6:30 am to drive the car around the runway - and repeat the process again in the afternoon.

This car is capable of emitting 20 different types of sounds - from the sound of hunting guns to the sound of enemy species - each sound effect chases a few birds. These sounds are also changed alternately to avoid the birds becoming "accustomed" to a certain sound.

With the larger and more gritty birds, Marcus was forced to step out of the car and point the speaker at them to chase away.

"During the time I worked there were enough birds - from the birds to the white belly eagles, as well as some other carnivorous birds. The birds are too small to be sucked into. engines will usually not cause any damage, but larger birds can cause engine fans to be badly damaged, so our priority is to chase large birds. "

If the use of sound proved to be ineffective, the airport staff would use the giant laser gun. This is almost the final solution to chase away the birds if the sounds are unsuccessful.

If the speakers do not lose, the airport staff will use giant laser guns.

"This gun shines a green laser light - only this color can chase the bird, and the blue and the red head are ineffective. We will have to point this light straight into the birds' faces , " Marcus shares.

However, birds are not the only animals that Marcus and his colleagues at the airport have to deal with.

"There was a time when a dog ran into the airport. We had no choice but to trap them. Not only that, sometimes we had to welcome the sea otters. "This species is under threat, so we are not allowed to set traps, we have to find another way to get rid of them. Sometimes I don't know if I'm working at the airport or zoo anymore."

Besides, Changi airport staff also have many other things to do - such as cleaning the airport runways. Because every day there are many flights departing and landing on runways, a large amount of rubber chips from tires will be left on the runway.

Clean up the runway.

These rubber chips when trapped on the runway will reduce friction and make landing unsafe.

To solve this problem, the airport workers will use a rubber cleaning machine - actually a large car with two "wheels" on the head capable of firing water jets with pressure. High to clean up the rubber cling on the road.

These rubbers will be sucked into the garbage container. The rest of the car will resemble the road-cleaning cars we often see.

In addition, there is a magnet bar on the car to absorb the metal fragments left on the runway.

These rubbers will be sucked into the garbage container.

When the cleanup was finished, the last job the airport staff needed to do was check the friction on the runway. This work is done thanks to a car capable of spraying water to create a thin layer of water on the road surface, from which the front wheels of the vehicle with friction gauge can accurately check friction. on the runway - equally important to ensure the safety of take-off or landing of aircraft.

So the next time you go on a plane, remember the hard work of so many people who are ensuring your flight safety.
