Do contrails cause turbulence?
Do contrails cause turbulence? Thus, these contrails indicate regions where there is strong wake turbulence caused by the aircraft in front of you that made the clouds. Heavier, slower aircraft make more intense wake turbulence.
What is the white smoke inside airplane?
What you're seeing is mist — hot and humid outside air rapidly condensing upon contact with the aircraft's onboard air conditioning unit that creates billows of water vapor.
At what altitude do planes leave contrails?
Contrails are human-induced clouds that only form at very high altitudes (usually above 8 km - about 26,000 ft) where the air is extremely cold (less than -40°C). Because of this contrails form not when an airplane is taking off or landing, but while it is at cruise altitude.
Why do airplanes cruise at 35000 feet?
The reason planes cruise at high altitudes is that they burn less fuel and can fly faster, as the air is less dense. At 30,000 feet and higher, it is also possible for aircraft to avoid weather systems, making it more comfortable onboard.
Do planes dump fuel before landing?
While fuel dumps don't happen every day, they're also not uncommon. Nor do they usually represent a major emergency. In fact if an aircraft is taking the time to dump fuel before landing, that's likely an indication that the issue forcing the plane to land is serious but not critical.
