Why do some aircraft have condensation trails and some do not?

Contrails are created under certain atmospheric conditions and depends on the pressures and water vapor. They are created from wing tips or propeller tips and engine exhausts. Each airplane varies in their design of these features. Many modern airplanes have wings designed with supercritcal airfoils that produce more lift---and therefore developes a lower air pressure. Some jet fighters also have special designed wings and wing tips that will create contrails in a tight turn that earlier aircraft could not perform. Thus the F-18 can fly very low and still produce contrails. There are many factors that contribute to the contrails so there is no way to predict which aircraft will produce one.

Condensation increases with greater?
Condensation Increases with relative HUMIDITY.
You have condensation in your toilet vent pipe?
No I just checked and mine has no condensation, thanks fro asking
How come water from AC?
Because the amount of water vapour that the air can carry before condensation occurs varies with temperature. If you take hot humid air aind cool it down some of that humidity will drop out as condensation - turn into water.
What is condensation polymerisation?
Condensation polymerisation is when two molecules of the same substance (monomer) react together to form polymer chain (like polythene) and eliminate a smaller (usually water) molecule. For example, Nylon-6 is prepared by using condensation polymerisation of ε-Caprolactum
What forms during condensation?
a gas
What do you call the tracks in the sky from airplanes?
Condensation trails or 'con trails'.
What is an airplane smoke trail called?
Contrails or condensation trails
What does the cloud name contrails mean?
Contrails is a shortening of condensation trails.
A good sentence for condensation?
The jet trails across the sky were caused by condensation. The condensation of the water on the outside of the glass left a ring on the table. The condensation fogged up his glasses when he walked into the house.
What do you call the long streams jet planes leave in the sky?
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.
What is the white smoke made of that is behind planes?
Condensation in the low temperature atmosphere of vapours found in the engine exhausts. Its name is a Contrail - condensation trails.
Why are trails produced by alpha and beta particles seen in cloud chambers?
ionization of air which triggers condensation.
Why do planes leave white trails?
The heat of the engines, especially jets, leaves a trail of white condensation in the cold atmosphere.
Why traces of smokes when aircraft fly in high altitude?
That is condensation from hot engines in cold air.
What is mintra level?
To aid the forecasting of condensation trails emitted (or not) from high-flying aircraft, a line marking the critical temperatures (altitude dependent), above which trails are not possible, is marked on a tephigram . The values are approximately -24degC at 1000 hPa (i.e. roughly sea-level), -39degC at 250 hPa (34000ft / 10.4 km) and about -45degC at 130 hPa (50000feet/15km). Using the MINTRA line (as it has come to be called - based on experiments by JK Bannon during World War II with the piston-engined Spitfire), a forecaster will mark two further lines on a tephigram: MINTRA minus 11degC (A) and MINTRA minus 14degC (B). If the ambient temperature (from the tephigram air temperature plot) lies between (A) and (B), then short, non-persistent trails are possible. If colder than (B), then long, persistent trails should be expected. However, some note should be paid to the relative humidity - high values will tip the balance to trailing (or longer/persistent trails.), even with air temperatures warmer than (A); ultra-low rh% will reduce the risk of condensation trails - the design of engines will have an effect as well. In broad terms, warm Tropical Maritime airmasses with a high but cold tropopause will result in a good deal of trailing, whilst cold, polar air-masses with a low, relatively warm tropopause will seldom give rise to significant aircraft trails.
Do commercial aircraft put out white smoke like military air craft do when they fly hi when it's cold out?
Yes, any aircraft makes vapour trails in the right conditions.
Do only military jets fly high enough to leave vapor trails?
No. If you live in the US, most of the vapor trails you see on any given day are the products of civilian jetliners, not military aircraft.
