The higher you go, the "thinner the air" - the less oxygen in the air. When you get to around 11,000 msl (mean sea level) there is not enough oxygen in the air to keep your brain functioning normally. You start to suffer from Hypoxia and a whole list of other ailments that are not particularly good for you. As you go higher, and the oxygen in the air becomes less and less, you starve the brain of oxygen and eventually kill it - not good. You can solve the problem by donning an oxygen mask - that supplies you with a supplemental oxygen source, or you can pressurize the aircraft, that virtually brings the oxygen in the plane to a level which is somewhere generally between 4,000ft and 8,900ft msl. It's much more comfortable (and practical) for airlines to pressurize the airplane than to have 150 to - what - say 300 oxygen masks hanging down from the ceiling at every seat.
What else can I help you with?
When you are landing in an airplane does the air pressure increase or decrease?
It increases. In an unpressurized airplane, the pressure increases because the air is denser at lower altitudes. In a pressurized airplane, the pressure increases both because the pressure must be equalized before the doors can open and because the hull is not designed to withstand an outside pressure higher than the inside pressure.
Is air pressure higher or lower when you are flying inside of an airplane?
Air pressure is always higher inside a pressurized airplane and about the same in an unpressurized one. As altitude increases, air pressure drops which results in less oxygen passing through the lungs and entering the bloodstream, hence the need to increase the proportion of oxygen or the pressure to be able to breathe. Federal Air Regulations require the use of either a pressurized cabin or the use of supplemental oxygen above certain altitudes. In addition to the lack of oxygen, there's the problem with loss of pressure at very high altitudes that could result in the formation of nitrogen bubbles within the blood and tissues. High altitude aircraft like the SR-71 Blackbird or the X-15 use fully pressurized suits for the pilots rather than have to pressurize the whole aircraft.
What fuel is stored as a liquid in pressurized tanks?
Propane and LNG, liquid natural gas are two of the most common. Hydrogen and oxygen used by NASA is also stored as pressurized liquid.
Which force is activated because of the mass of the airplane and works to pull on airplane to the ground?
The force that is activated because of the mass of the airplane and pulls the airplane towards the ground is gravity. Gravity is the force of attraction between two masses, in this case, the Earth and the airplane.
How can you calculate the acceleration of a commercial airplane?
Acceleration of a commercial airplane can be calculated by dividing the change in velocity during a specific time interval by that time interval. This can be measured using instruments like accelerometers on the airplane or by analyzing data from the airplane's flight instruments.
What happens if an airplane is not pressurized?
death happens if the airplane is over 20000 feet
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.
Is packing soda on an airplane possible?
yes, the cabin and cargo holds are pressurized.
Do beer cans explode on an airplane?
nope, the luggage compartment as well as the cabin are both pressurized.
Can you boil water on a airplane?
Yes. Airplane cabins are usually pressurized to around 5,000 feet. So imagine you are just boiling water at 5,000 feet.
What is the oxygen level of the air expected to be when flying in a pressurized cabin of a plane?
The percentage of Oxygen in the air is the same in airplane as it is outside the airplane. The only difference is the pressure levels. If the pressure drops too much then the total amount of Oxygen will be insufficient for you to breath and you will pass out. The airplane only carries oxygen for use in emergency and is dispensed in the oxygen masks of the crew and passengers. Maybe your Question is asking what the total volume of oxygen is available in a pressurized airplane. I don't know that.
Why is an airplane cabin air pressurized?
At altitudes above 10,000 feet there is not enough air for humans to breathe. Aircraft cabins are pressurized so the pressure is equal to that at about 7,000 feet. Commercial airliners fly at altitudes up to 40,000 feet.
What kind of license do you need to drive an airplane?
Typically, operating an airplane is called "flying" and it requires a private pilot license (at minimum) from the FAA. - - - - - It depends on the kind of airplane it is, and what you plan to do with it. The licenses and certificates you need to fly a Piper Cherokee (single-engine piston airplane that isn't pressurized) are far different from what you need to fly a 747.
Is the air pressure in a flying airplane greater that outside the flying airplane?
In a commercial airliner flying at cruising altitude, the air pressure inside the airplane is considerably higher than the air pressure outside. The air pressure outside is too low for people to breathe comfortably, so the interior is pressurized.
Why does the word pressurized mean that a crew cabin is filled with air?
If the crew cabin were not pressurized, it would still be full of air, except that the air would be at the same pressure as the air outside. Only if the craft is actually in outer space would there be no air outside. In the case of an airplane, there has to be air outside in order for the airplane to fly, but that does not mean that there is enough air to breathe. Pressurizing the cabin means that the air is at a sufficient pressure to be breathable.
Why must airplane cabins be pressurized?
Because at altitudes above 10,000 feet there is not enough air for humans to breathe. Aircraft cabins are pressurised so that the internal pressure is equal to that at about 7,000 feet.
Why we need Suffocate in air shipment?
Air freight may not be pressurized because it has no need to breathe as living things do. When the airplane reaches its altitude, the oxygen content is low enough to cause death.
