When planes fly above 25, feet or so, the temperature is very cold (approximately degrees Fahrenheit). When those exhaust fumes are shot out of the back of an airplane, the water vapor hits the cold air and condenses, leaving the contrail behind. Depending on the humidity, temperature, and the chemical composition of the exhaust, contrails last in the sky for varying amounts of time, and those variables also determine the size and length of the trails. These contrails are more than pretty streaks, however; they can also be used to determine changing weather patterns or oncoming storms –. But why do some planes leave white trails and others do not? White trails from airplanes are often called condensation trails or contrails, but they could also be called clouds. The main reason behind their appearance is the temperature difference between hot humid air around a plane’s engine and low temperatures outside the aircraft. Whether or not condensation trails will form mainly depends on height and composition of the surrounding atmosphere.  Will the white trails appear in the air depends on the humidity. If a plane flies over a region with dry air, there are no small particles of water in the air and nothing to freeze outside. There will either be no condensation trails from the aircraft in such areas at all or they will be very pale and disappear quickly. But jets leave them more often and more distinctly, because of the altitudes they are at and the enormous sudden pressure and temperature drop the air experiences as it leaves the engine. 0. 0. Max Cruise. Lv 7. 10 years ago.  10 years ago. The term is contrail. Contrails (short for "condensation trails") or vapour trails are artificial clouds that are the visible trails of condensed water vapour made by the exhaust of aircraft engines. As the hot exhaust gases cool in the surrounding air they may precipitate a cloud of microscopic water droplets. If the air is cold enough, this trail will comprise tiny ice crystals.[1]. The wingtip vortices which trail from the wingtips and wing flaps of aircraft are sometimes partly visible due to condensation in the cores of the vortices.

100 planes in the sky leave trails that persist and spread, jet planes leave trail 10 other planes, in the same skyleave short-lived trails, or no trails at all.

Contrails are actually a type of cirrus cloud. When the air is wet and cold enough the trails can stay around for a long time, and sometimes spread out. So you see helpful images like this. But this is wrong. Contrails can fade away, and contrails can persist and spread.

It depends on the air they are formed in. 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 planws. Some engines will trakl a contrail in the air where another engine will not.

Here, for example, are an Airbus A maiden flight: on the left, leaving contrails, and a Boeing maiden jet planes leave trail 10 not leaving contrails.

You can also get a Jay Jay Jet Planes Lyrics similar effect with engines at different power settings, especially if it affects the exhaust temperature. This can occasionally be seen with high altitude refueling, when the plane being refueled cuts the throttle to near idle in order to separate from the tanker.

The reason that one plane makes tral or makes contrails that persist, and the other plane does not, is that they are in different regions of the air. When the plane is in wet air, it makes a contrail. In dry air, it does not.

Surely, you might object, they would have to be miles apart? Well, no, and that brings me to another point I fear I must emphasize:. Look at the bottom of those clouds, see them extend off into the distance. They form a layer at a specific altitude.

Above that altitude there are clouds. plznes it there are no clouds. The difference between clouds and no clouds is just a few feet. Again they are in a flat layer. The difference between being in the layer and not in the layer is just a few feet. This layering of the air into wet jet planes leave trail 10 dry layers is not limited to clouds. Seemingly clear air also contains exactly the same kind of variation in layers.

This was very neatly illustrated by the recent launch of the Je Dynamics Observatory. As it ascended it did not jet planes leave trail 10 a contrail, until it hit a layer of wet air, when it left a contrail that lasted quite a while, and then it went into dry air again, and no more contrail.

So, if a plane were flying in that middle region then it would probably leave a persisting contrail. If it were above or below it then it would not. But, you may cry, the planes are at the same altitude.

These planes fly at 30, to 40, feet. I took one image of a jet nominally at 35, feet. Then scaled it for 34, If the top plane was flying at 20, feet, then the bottom would be jet planes leave trail 10 18, feet, jet planes leave trail 10 nearly 2, feet apart, and looking pretty much the same to the naked eye. And that jet planes leave trail 10 with the same model of plane, directly overhead, and right next to each other.

A situation that almost never occurs. Just look at this:. They look about the same height, right? And look at some planes on the ground, where we know they are all the same distance from the camera.

The differences in size are trali significant:. The planes leave different trails because the planes are at different altitudes. Debunked: High Bypass Turbofans do not make Contrails [actually they make more] — A more detailed look at why modern engines make contrails in a wider range of conditions. The key difference is the exhaust gas temperature, as explained in the more recent Metabunk article. This is an excellent addition! Jet planes leave trail 10 aircraft, same altitude- different engines, different contrails.

I have a little addition to your information. Sometimes an extra trail is caused by the dumping of wastewater via vents on the underside of the fuselage. When looking at the Tu we se that the water dump point is at the same location as the origin trail in the video.

Here is a picture plnaes of 2 airliners including the corresponding radar image. I mostly say: Different engines of different age with different powersettings on different locations create different contrails. Though this will vary with plane. Some APUs auto shut-off at altitude.

I think APU trails are pretty rare. Some of the supposed photos might be mast drains, or even a third tail mounted engine not visible from the ground. We rarely use the APU in flight, the most common reason to keep the APU running during takeoff is to have more power on the engines, although this is different for each type of aircraft.

On takeoff the APU provides bleed air, preventing a power reduction on the engines. In flight it backs up both electrical and bleed air system. We can use the APU bleed for 2 packs up to We can use the APU for power up to I am not a rocket scientist, I am only a layman, but would like to point out that rocket exhaust from an Atlas V rocket or whatever types this may be is not the same as engine exhaust from a commercial airliner engine.

They are made up of different types of gasses and therefore cannot be used to compare anything in this argument. What if rocket exhaust due to its composition exhibits different effects as it passes throught different layers of humidity. Do you have observations of other rocket launches?

Is rocketry another of your hobbies? Rocket fuel met additives like oxydisers. Maybe that jet planes leave trail 10 this white looking trail that we see.

Rocket launching can be very technical. Sometimes different types of fuels and mixtures are used at different times during a lauch to achieve higher buring rates to gain velocity.

Maybe that is what we are seeing there. Sometimes they vent of stuff during the course of a rocket launch. Do rockets go straight up as your arrow indicates. Did this rocket go straight up? Where is your proof that this rocket went straingt up?

What is the operating temperature of rocket exhaust during the various stages of assent? What are the differences in temperature and humidy that enable you to lable the photo as a trali or dry plqnes. Do you have the met data from this location for the different layers of atmoshpere?

You have left jet planes leave trail 10 with way more question than you have answered. Can you please help me understand? Your photo of the fifth contrail above could actually also be from another jet that is flying at a higher altitude than the jet we see. We cannot see this second jet because it is higher and smaller than this big jet and is being obscured by the big jet.

Is this not jet planes leave trail 10 This is a bad photo. Without a good photo this is a bad argument. Which is what this post is about — that there are some regions of air that are different from other regions of air. Contrails form in those regions. Both produce lots of water. Jet planes leave trail 10 label the regions as wet and dry based on where the contrail shows up, the description from the rocket scientist.

Since the rocket was ging into orbit it would not be going exactly straight up all the way, but not too far off. It certainly started straight up. It does not change the argument that some planes operate the APU in flight, and this creates an additional contrail. Using this argument, and looking at the second photo from the top, are those two planes at exactly the same altitude? Perhaps the plane on the right hrail flying in a different layer an that is why we a re not seeing jer formation of a contrail.

Do you have the actual measured flight altitudes of these two aircraft? Is jet planes leave trail 10 trall ahead of the other? Without a line of reference or actual flight altitude data, this is a bad photo should not be used in this aurgument. The photo shows two planes that were part of a study into the formation of contrails. They were deliberately jet planes leave trail 10 together at the same altitude.


Sometimes planes leave contrails, and sometimes they don’t. It depends on the weather, and specifically, it depends on the weather at altitude. It’s also very localized. A plane might leave a trail in one region, and another plane a mile away might not leave a trail. NASA have. Originally Answered: Why do jet planes leave trails? Jet planes give out exhaust burnt out gasses from the engine. But in certain atmospheric conditions & altitude those gases won't mix up with the atmosphere easily & then they leave trail of those gases.
