What else can I help you with?
Why air crafts at high altitude must have pressurized cabins?
Mostly not enough oxygen in the air at the low pressure up there.
Why are airplane cabins pressurized?
Airplane cabins are pressurized because humans cannot breath at a very high elevation.Aircraft are pressurized to allow them to fly higher. Without pressurization, the amount of oxygen in the air would not be sufficient for humans to breathe.
What are cabins with normal air pressure at high altitudes?
high altitude chambers
Why don't helicopter cabins have to be pressurized?
Helicopters don't generally fly high enough for cabin pressurization to be necessary.
Why do passenger aircraft have pressurized cabins?
To allow passengers to breathe sufficient oxygen, needed to survive, even in high altitudes.
Why do you need to pressurize cabins in aeroplanes?
Airplanes travel faster at higher altitude. But pilots don't travel better at high altitude. Above 10,500 feet, people start to be affected by oxygen deprivation: tunnel vision, slower reflexes, slower reaction times, impaired judgement, etc. Aircraft are pressurized so people don't fall asleep and/or die at high altitude. At regular commercial airline altitudes between 10,000 and 40,000', all aircraft have to have pressurized cabins. Pilots wear oxygen masks (with the gas turned off) at those altitude in case there is a pressurization failure or a rapid cabin decompression. If one should eventuate, they already have on the mask, and all they have to do is turn on the oxygen.
How high can a helicopter go?
I believe the FAI world altitude record for a helicopter is 40820', and helicopters can now land on the top of Mount Everest, just over 29,000'. But practically speaking, helicopters rarely go over 10,000 feet as that's the altitude above which pressurized cabins and supplemental oxygen are required.
Why the aircraft is pressurised?
At 35,000 feet, a human would suffer severe oxygen starvation without a pressurized cabin. Also known as "death". A pressurized cabin in a commercial - or military - airliner is essential at high altitude.
How does a high altitude pilot overcome the lack of air pressure?
They could not remain conscious unless they either pressurized the cabin of the plane or wore a face mask that supplies them with pressurized air.
Why are air plane cabins pressurized?
Outside the plane is way less pressure and less air to breath. If inside the plane was the same pressure as the outside, people might die depending on how high the plane is. ***************************************************************************** FAA law mandates an un-pressurized aircraft the pilot and co-pilot must wear oxygen masks at or above 12,000 feet ASL altitude. Hypoxia sets in with no warning and no symptoms.
Why are cabins of jet planes pressurized?
Pressurization is for the comfort of crew and passengers. The planes fly higher to save on fuel. The less dense air higher up causes less drag. It is also unfortunately harder to breathe. Pressuriziation makes it easier to breathe without special equipment, like breathing apparatus or oxygen.
Why at high altitude the amount of oxygen decreases due to increase of carbon dioxide?
Most airplanes fly at high altitude because it is faster and safer as long as the cabin is pressurized. There is less clouds and turbulence. The airplane uses less fuel.
