Orange is a well known and easily recognizable color, but why are most aircraft made white?

Early Diamond Aircraft designed aircraft with a restrictive condition: the outside temperature should not be higher than 38°C, because above this temperature, the main wing structure of the aircraft was not strong enough. Compared to other colors, white reflects all the bands of light, and light energy is not converted into heatJust like we usually wear white T-shirts, the white fuselage can reflect sunlight and heat, so that the plane will not overheat.

In addition,When the plane is grounded on the ground after flying, the white color also cools down faster. Therefore, keeping the body temperature low is an advantage of white.

Nearly half of the aircraft currently flying in the skies are leased by airlines to aircraft leasing companies. Rather than repainting the entire aircraft, it is significantly more economical to lease a standard white aircraft and change the logo, especially since some aircraft leasing companies do not allow the lessor to change the color of the aircraft. When maintenance personnel perform routine inspections of aircraft, the white fuselage makes it easier for them to identify problematic areas, such as oil leaks or corrosion marks.

In addition,In the unfortunate event of an accident, whether in the mountains or in the sea, the white fuselage has the advantage of allowing search and rescue personnel to identify it more quickly. Conversely, if it is a different color or a dark color, it may lead to an increase in search and rescue time.

The cost of color painting an aircraft is between $50,000 and $200,000, and the entire painting process takes 2 to 3 weeks, which can also result in a loss of revenue. More color = more weight = more fuel consumption = higher cost,Taking the Boeing 747 as an example, the decoration of the 747 requires at least 250 kg of paint, while the weight of the paint for polishing the whole machine is only 25 kg. In the case of EasyJet Airlines, the use of a thinner aerodynamic fuselage coating alone saved the company a full 2% of operating costs.

Imagine that the annual fuel cost is about $1.2 billion, so 2% means about $22.4 million in savings.

Do you suddenly feel that the fuselage paint is getting taller?

Red itself is a warm color, so it should be complemented by cool colors, such as: light blue, light purple, turquoise, light yellow. The best colors to match orange are: white, black, and blue.

Because in the sky, white is easier to distinguish than orange-red.

Because white reflects most of the light, it is relatively safe.

I think that if the plane is orange, it can be dangerous for the plane.

This is to match the color of the sky in the sky. And it doesn't affect the line of sight.

You may want the plane not to be too ostentatious to attract the attention of criminals.

Because white in the sky allows the aircraft to absorb less heat, making it safer to fly.

Because the white color is more conspicuous and more heat dissipating.

Because in this way, the effect of light on it can be reduced, so it will look like this.

Maybe the design company thinks it's safer to use this color.

In fact, it is easy to discern who this person is when you see the face of a very familiar person around you. For example, when you go to Africa and see strangers, it is difficult to distinguish them.

It's the same for animals, if you have two Huibu pure spike pet Bihong puppies, because they are very familiar, they are also easy to identify. It is difficult to distinguish between other people's dogs of the same color and size.

Parvovirus infection in dogs is commonly known as "turning the intestines", and the infection rate and mortality rate of puppies within one year of age are relatively high, but you don't have to worry about it, if you use the appropriate method in the early stage, it can also be improved.

First of all, you have to determine whether the dog is a symptom of parvovirus infection, and the main symptoms are: 1Diarrhea and the feces have a fishy smell and are dark brown or dark red in color.

2.Vomiting is frequent and the vomit is a white, viscous foam. 3.

The dog's nose is hot and dry, and he is listless. If you have the first two points I have described above, you can preliminarily judge parvovirus infection, at this time, the first and most important thing is to stop vomiting for your dog, so that the medicine will not be spit out, you can use: metoclopramide or vitamin B6, but do not use it with anti-inflammatory drugs, followed by anti-inflammatory and anti-diarrheal drugs for dogs, at this time you can use dexamethasone or gentamicin, here is also to remind you to use anti-inflammatory drugs and antidiarrheal drugs separately, preferably with an interval of one hour.

During this period, try to replenish water to the dog to prevent dehydration, and judge whether it is dehydrated: you can gently pinch up a little of the dog's back, and see if the fur you pinched up quickly returns to its original state, if it does not return to its original state quickly, it is already dehydrated, at this time you must replenish water for your dog, if the dog does not drink it himself, you can use a clean needle or a used eye medicine bottle, but be sure to clean it, Simply inhale clean water and put it in your dog's mouth.

I know that the dog is sick as the owner will be very anxious, will give the dog a lot of medicine, but at the same time in a hurry but forget the mutual taboos between the medicine and the medicine, so you don't worry, the best time to feed the medicine is about half an hour to an hour, so that each time the medicine will be fully absorbed by the dog, to achieve the efficacy of the drug itself, if they are all given to the dog together, there will be mutual rejection between the medicine and the medicine, and the dog can not be very absorbed, almost equal to the same as not eating, Give the dog so much to eat at once, and the dog will be even more uncomfortable.

So first of all, you must not be too anxious, you must pay attention to the interval between taking medicine, so that you will get twice the result with half the effort!

To feed the intestinal worms in advance, feed less meat, do not go outside and contact with other unclean dogs, some time ago I fed a puppy, I love it very much, as a part of their own family, but unfortunately did not take care of it, is the dog intestines this disease died, I hope you can take care of your dog, I wish it a soon, lively!

Puppy in 2-3 months can not give him meat, can not give him too much milk, will cause the phenomenon of intestinal turning, I have a puppy just did not pay attention to these things, and finally in 3 months of intestine sacrifice, and then have experience, now the dog at home 3 months at 3 months at all at all. I'm over 2 years old now. You'd better take him to the hospital now.

Dogs generally will, which helps dogs, generally two to three months on.

Dogs generally turn their intestines, which are caused by the parasites in the body itself.

Dogs that turn their intestines have no appetite and will have diarrhea, so pay attention to what they eat to be easy to digest and do not feed carnivorous things. In addition, it is also very important to let the dog rest more, don't always tease it, and nourish the spirit.

It's a bacterium, you just need to get all the vaccines and pay attention to the dog's nutrition, and you're good to go.

How many months does the dog turn its intestines? Why?

Cancer is an empathetic and gentle sign, the main lucky colors are white, silver white, gray Cancer lucky colors are: white, silver white, gray, purple, green.

And, most of the cancers themselves like these colors.

Sinking, the character of the inner image may make you like black, silver-gray sincere heart, will make you more suitable for red, big red, fire-like red and Cancer conservative character, pure and kind, innocent and simple outlook on life, white, is the best choice.

Many friends like to drink, but they don't know how to distinguish it, so it is very practical to teach everyone to easily distinguish the quality of liquor.
