The occupants require it.
air
Nitrogen is filled in aeroplane tyres.
this means that the air outside the aeroplane is too thin for us to breathe and the air has to be pressurised in the aeroplane. that is why the aeroplane has masks above your seat so if the air becomes to thin the air coming through the mask is the right for you to breathe.
Cabin
Nitrogen
Aeroplane means a vehicle with wings which flies through the 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.
They are called flight attendants (also cabin crew, stewards/stewardesses, air hosts/hostesses and cabin attendants)
It is because an aeroplane's cabin is pressurized, meaning that it is sealed off from the atmosphere. This prevents air escaping and keeps the pressure constant.
uh, it's an cabin AIR FILTER... it FILTERS the AIR in the cabin!!!
It was not built with a cabin air filter.It was not built with a cabin air filter.
Mountaineers carry oxygen cylinders with them on high altitude mountains like Mount Everest. This is because the higher the mountaineer climbs the less air there is to breathe.When you travel in an aeroplane at a high altitude the plane will be pressurized. A cabin air pressure at cruising altitude is lower than air pressure at sea level. At typical cruising altitudes in the range 11 000-12 200 m (36 000-40 000 feet), air pressure in the cabin is equivalent to the outside air pressure at 1800-2400 m (6000-8000 feet) above sea level.
