Some airplane does have white thick smoke in the sky. What is the reason of this thick white smoke?

this smoke remains for 15 to 30 mints in the sky. if this cause an environmental problem or not. If does, why can鈥檛 they stop these kind of airplanes.Some airplane does have white thick smoke in the sky. What is the reason of this thick white smoke?Contrails - a byproduct of combustion, like your car exhaust, is water vapor



Altitude - for every 1,000 ft - you lose 3 degrees of warmth



therefore, at 39,000 feet you have effectively dropped below FREEZING temperatures

so that water vapor hitting the super cold air FREEZES

into ice crystals which are now visible



when I was a student flying - I heard a pilot report over Daytona Beach, FL USA

at 41,000 and his outside air temperature was minus 40 degrees - - - - in MAY



sometimes light refracts - and causes the contrails to change colors



combustion from cars causes an environmental problem

are they going to stop cars?

The "smoke" is water, identical to that found in clouds.



The engines of aircraft produce exhaust that contains mainly carbon dioxide and water. When aircraft fly at high altitudes, the surrounding air is very cold, and the water in the engine exhaust condenses into liquid or even ice, forming long clouds that trail behind the airplane. Depending on weather conditions, these condensation trails, or contrails, may persist for hours, or may evaporate after a few minutes. Only the water condenses in this way, since carbon dioxide has a melting point far too low to condense, even in the coldest air.



Since these trails are just water, they do not cause any problems for the environment. They have the same effect as any other clouds.



Human beings also produce carbon dioxide and water as their "exhaust," and they can produce "trails" as well when they exhale on very cold days. The principle is exactly the same.Some airplane does have white thick smoke in the sky. What is the reason of this thick white smoke?because the air in high altitudes is very cold .the hot air from the exhaust of the jet engine condensate. Is a similar process like the clouds are created . Yes the air crafts are known to be vehicles which cause highly pollution but there are doing improvements on reducing these factorSome airplane does have white thick smoke in the sky.

What you are seeing are known as contrails, condensation trails. If is nothing more than water that was expelled by the engine and condensed into ice crystals. It is not an environmental hazard.Some airplane does have white thick smoke in the sky. What is the reason of this thick white smoke?Yep. Contrails dude. Nothing but water, and ice. Just depends on the air density.
