Hotfreeze: You should be ashamed of your crazy mind. Fuel dumping (or a fuel jettison) is a procedure used by aircraft in certain emergency situations before a return to the airport shortly after takeoff, or before landing short of its intended destination (emergency landing) to reduce the aircraft's weight. |

That's contrails Contrails (/ˈkɒntreɪlz/; short for "condensation trails" are line-shaped cloudsproduced by aircraft engine exhaust or changes in air pressure, typically at aircraft cruise altitudes several miles above the Earth's surface. Contrails are composed primarily of water, in the form of ice crystals. The combination of water vapor in aircraft engine exhaust and the low ambient temperatures that exist at high altitudes allows the formation of the trails. Impurities in the engine exhaust from the fuel, including sulfur compounds (0.05% by weight in jet fuel) provide some of the particles that can serve as sites for water droplet growth in the exhaust and, if water droplets form, they might freeze to form ice particles that compose a contrail.[1] Their formation can also be triggered by changes in air pressure in wingtip vortices or in the air over the entire wing surface.[2] Contrails, and other clouds directly resulting from human activity, are collectively named homogenitus.[3] 2 Likes |

stankezzy:I never said maximum take off weight is 312000kg. That's the maximum landing weight of a Boeing 747. Different aircraft has different landing weights. The take off weight is always heavier than the landing weight. Sometimes above 420,000kg. |

TechCapon: Oga fuel dumping occurs and it's done in a controlled pattern from nozzles at the wing tip and you can never see it from the ground , it will take a very eagle eyed passenger around the wing area to see it ...Please let's stop all this ignorant misinformation and please never argue about planes with me ..I hope you know not all commercial planes can even dump fuel e.g the Boeing 737 doesnt dump and must do a burnout if it must shed fuel weight for safety...Nigerians are the only people who don't know something be arguing witgose that thoroughly thoroughly know it ..I thoroughly know planes so better take my advice sir 8 Likes |

lightblazingnow: You're an unenlightened twerp and you wear your ignorance like a badge of honour. How many times have you seen this procedure with your own eyes? You think aircraft dump fuel indiscriminately that you'll see it while eating leftover rice in your kitchen? Funny clown. Go and read the OP's conclusion about the white trails we see behind airplanes every time and stop advertising your foolishness here. 3 Likes |

McEphiks:Yeah... it's always good to confirm, but hope you also tried to confirm what I said too about contrails being the more prevalent reason behind those white trails and not fuel dumping which happens very rarely (mainly during emergencies)? 2 Likes |

Another reason for fuel dumping is engine failure. If a 4 engine aircraft loses an engine mid flight, the earlier calculations made will be altered hence dumping off some fuel will be necessary. TechCapon: |

Ur definition for Zero Fuel Weight(ZFW) is wrong. *ZFW is the actual weight of an aircraft + Passengers weight + Baggage weight(that is payload) WITHOUT FUEL that makes it Zero Fuel as its name implies. * Dry operating weight + Payload + Zero fuel load = Take off weight THIS IS WRONG! Thr is noting lyk Zero fuel load. wht ll gv u Take off weight is: Dry Operating weight + Payload + Take Off Fuel= Take Off Weight |

What exactly is the white we see coming off an airplane in the sky. Sometimes in the summer you can lookup and see many streaks in the sky. They are much longer and last longer in the summer than winter. Please tell me what causes this and why they last longer in the summer. The white streaks you see coming off airplanes are called contrails, which is short for condensation trail. Contrails are actually clouds made by the airplanes. There are two types of contrails. Most contrails people see are caused by a jet's exhaust. The exhaust has some water vapor in it which mixes with the air when it leaves the jet's engine. Sometimes this mixture has too much water vapor for the air to hold and it condenses into a cloud. This is the most common kind of contrail and it lasts the longest. The other kind of contrails are form by an airplane's wing. Air moves over the wings really fast and cools because of the low pressure. The cool air can't hold as much water so some of it has to condense. This kind of contrail isn't as long-lived as the other kind. The picture to the left is an example of this kind of contrail. Contrails last longer when there is a greater amount of water in the air. During the summer, the air generally has more water vapor in it than during the winter. You might notice that it's usually more humid in the summer. Because it's more humid in the summer, contrails take longer to evaporate. That's why they last longer than in the winter. |
