A distrail is the opposite of a contrail. Where an aircraft passes through a cloud, it can disperse the cloud in its path. This is known as a distrail (short for "dissipation trail"). The plane's warm engine exhaust and enhanced vertical mixing in the aircraft's wake can cause existing cloud droplets to evaporate.
Aircraft sulfur and water emissions in the stratosphere tend to deplete O 3, partially offsetting the NO x-induced O 3 increases, although these effects have not been quantified. [10] Light aircraft and small commuter aircraft fly lower in the troposphere, not in the tropopause. Contrails and cirrus clouds Contrails and cirrus clouds
Aircraft contrails (white lines) and natural clouds. Aircraft leave behind visible contrails (also known as vapor trails) as they travel. These contrails both reflect incoming solar radiation and trap outgoing longwave radiation that is emitted by the Earth. Because contrails reflect sunlight only during the day, but trap heat day and night ...
Condensation trails , which form in an aircraft’s wake, can also contribute to climate change in outsize ways. Major airlines are teaming up to tackle planet-warming plane contrails Skip to main ...
Contrails are composed when hot, humid air from the engines condenses into ice crystals in the cold air, the National Weather Service says. While they often fade quickly, especially in dry weather ...
The problem particularly affects airports at high altitude, where the air is already naturally thinner, and with short runways, which leave the plane with less room to accelerate.
Contrails left by an aeroplane in holding pattern. Maximum holding airspeeds (MHA) are established to keep aircraft within the protected holding area during their one-minute (one-minute and a half above 4,300 m (14,000 ft) MSL) inbound and outbound legs. For civil aircraft (not military) in the United States and Canada, these airspeeds are: [1] [8]
