There are 3 main reasons for choosing this color

1. providing heat advantage
2. easy detection of cracks / cracks / cracks in the body
3. low cost

Heat Advantage
white color is a perfect reflector compared to other colors, it reflects almost all the light falling on it and prevents overheating of the plane. If the plane is painted with a color outside of white, this color absorbs all of the heat and causes the aircraft to expand. but it does not expand because it reflects the white color light, at least it does not expand to the extent that the flight is dangerous.

Easy detection of fissures in the body
planes are regularly checked for cracks / cracks / scratches. flight safety as predicted. white color is the best color for these cracks to be noticeable because the cracks / cracks will always be darker than white. it also helps to notice white color, wear and oil leaks.

In addition, white is the most noticeable color in the event of an accident. especially at night. a white plane that has fallen into a deep blue sea will be more noticeable than other colors.

Less costly

Airplane painting is a costly business. labor force, money and time. (a passenger plane takes about 2 to 7 days to paint, so much money is so short), and of course the paint that covers the entire body is an additional weight to the aircraft, which increases the cost of the flight. (The complex airplane painted about 100 kg.)

also colorful airplanes are cheaper than white airplanes. the airplane company / person will want to paint the colors of the jetty bazaar or their own company, which reduces the sales price, resulting in additional costs on board.

There is also a white color fading state. planes are subjected to different atmospheric conditions at high altitudes. Due to these conditions, the colors of the colored planes fade and this leads to the necessity to paint the plane more frequently in order to protect the aesthetic image, the cost increases. (the cost of the complex plane varies from $ 30,000 to $ 70,000, as well as the fact that the plane sleeps 2-7 days).
