Why air crafts at high altitude must have pressurized cabins?
Mostly not enough oxygen in the air at the low pressure up there.
Why air-crafts at high altitude must have pressurized cabins?
There is not enough oxygen in the air at altitudes above about 17,000 feet. In addition, as you ascend, the temperature decreases. The temperature in which jet airliners fly often is minus 40 degrees or lower.
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.
What do space shuttles and under water crafts have in common?
Space shuttles and underwater craft both must be air tight, and must carry an air supply with them.
Why must a astronaut were a pressurized suit in space?
Astronauts wear pressurized suits in space to protect themselves from the vacuum of space, which has no air pressure. The suit provides a breathable atmosphere, regulates temperature, and maintains the necessary pressure for survival in the harsh conditions of space. It also shields astronauts from harmful radiation and micrometeoroids.
How do figer out to rent between 35 and 40 square yards of space for big crafts show. The space must be rctangular and the side lengths must be whole numbers. Find the numbers between 35 and 40?

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 must an astronaut wear a pressurised suit in space?
An astronaut must wear a pressurized suit in space to protect against the vacuum of space, which lacks oxygen and has extremely low pressure. The suit maintains a stable internal environment, providing breathable air and regulating temperature. Additionally, it shields astronauts from harmful radiation and micrometeoroids. Without this protection, human life would be unsustainable in the harsh conditions of outer space.
Can you send mosquito repellent on a plane?
No. Aerosols must go by ground. They can explode when pressurized.
Why must airplanes be pressurized?
At the high altitudes which airliners fly in, there is less dense. Since air is good for us humans, the cabin is pressurized in order to provide enough air to breathe.
What is a non-pressurized recovery container?
is a clean recovery container which must have 1000 microns recovery
Why must blood from the patients vein be pressurized?
So doctors (or nurses) can see the vain better
