What is the smoke coming out of planes?
What is the smoke coming out of planes? Condensation in Exhaust Gases As the airplane's engines release exhaust gases, moisture vapor is released as well. The cold temperature and low air pressure at high altitudes forces this moisture to condense, which creates the characteristic white smoke trail for which airplanes have become widely known.
What causes airplane contrails?
Their growth is enabled by the presence of water vapor in the exhaust gases and ambient relative humidity greater than 100%. Unlike those clouds that form without any human intervention, contrails are a result of the exhaust from planes.
What is the steam coming out of airplane?
These clouds are contrails, short for condensation trails. Water vapor is one of the byproducts of jet fuel combustion and will turn into ice crystals in the cold air at the high elevations where jet airplanes fly. Those ice crystals create a cloud (the contrail), which does not pose any public health risk.
What do they smell in the air on the plane?
Jet Fuel. The distinct smell inside commercial airplanes is often attributed to jet fuel. During flight, commercial airplanes burn a mixture of jet fuel and oxygen in their engines to produce propulsion. When jet fuel burns, it creates odorous vapors that may enter the cabin.
Why do Airplane vents smoke?
That's because the aircraft's onboard air conditioning system is quickly cooling and condensing the humid air outside. As a result, waves of water vapour are released to make it all a good environment to breathe and travel smoothly. The whole process may often be called Cabin pressurization.
