jet plains have a white trail behind because of the moisture for some time. in higher layer of atmosphere where there is hot air to disturb it. this trail is suspeded for a long time. What is an Airplanes white trail? The white trail you see behind an airplane in the sky is called a contrail. It's an artificial cloud made by the exhaust of jet aircraft or from the wingtips. What is the white smoke behind the passenger plane? It's the fuel from the engines.  Yes sometimes. The white trail is called a 'contrail' and is caused when water in the air through which the plane is flying condenses out on particles produced from the plane's engine exhaust. Thus any plane with an engine can produce a contrail if the conditions are right. Why do airplanes give out white smoke while in flight?. Most jet contrails are produced from passenger aircraft. On a. clear summer day it's not unusual to see the sky criss-crossed. with jet contrails. The temperature of the air is more important than the altitude. or the speed of the jet.  Jet Planes Leave A White Trail Behind Them Because Ep Vapour trails, or Contrails, are formed when hot, humid and high pressured AIR (not fuel or chems) from an aircraft engine is mixed with the surrounding air that is at a low temp and pressure. 0. 0. Jets leave white trails, or contrails, in their wakes for the same reason you can sometimes see your breath. The hot, humid exhaust from jet engines mixes with the atmosphere, which at high altitude is of much lower vapor pressure and temperature than the exhaust gas. The water vapor contained in the jet exhaust condenses and may freeze, and this mixing process forms a cloud very similar to the one your hot breath makes on a cold day. Jet engine exhaust contains carbon dioxide, oxides of sulfur and nitrogen, unburned fuel, soot and metal particles, as well as water vapor. The soot provides con.

When an aircraft passes by overhead, it sometimes leaves a trail. These white lines of cloud, marking the path of the tgem, are known as contrails. But why do they leave them, what are they made of, and are they always the same? Contrails are literally tiny clouds. They are formed from water vapor which freezes around small particles from the aircraft exhaust. Much like a car might make a little white cloud near its exhaust on a cold morning, a plane will often leave a trail if the conditions are right.

Exhaust from jet engines is pretty much all water vapor, although there can be trace content of sulfur oxides, carbon dioxide, nitrogen, unburnt fuel, net and small particles of metal. These aerosols provide condensation sites for water vapor, as do any small particles in the air it is flying through.

Some aircraft leave long, defined jet planes leave a white trail behind them because java that persist for several hours after the plane has passed; others leave very short trails tfail disappear fast. Why is this? Contrails are generally categorized into three groups; short-lived, persistent non-spreading and persistent spreading.

Sometimes, even in the same patch of sky, one plane will leave a trail and one will jet planes leave a white trail behind them because java. Planes with hotter engines are less likely to form contrails, as the heat of the exhaust prevents ice from forming.

Modern planes with more efficient engines burn hotter, but use bypass air to cool the exhaust, making them more likely to leave contrails in a wider range of situations. However, the simplest reason for whether a plane makes a contrail or not is down to the environment in which it is flying. One is flying in moist air, while the other is flying in drier conditions.

Now there are two main reasons why some planes leave trails and some nearby planes do not. The less common reason is that different planes have different engines. Some engines will leave a contrail in the air where another engine will not. Most aircraft that leave trails aren't leaving smoke. It's condensed water vapour; essentially, clouds. These are called contrails. This can be caused by the water in the engine exhaust condensing, or by the disruption of the air by the passage of the aircraft triggering the condensation of .
