Aircraft Pressurization Beginner's Guide - AeroSavvy
Dec 31,  · In Aerospace Engineering. Although there are exceptions, most commercial jets fly at around 28, to 35, feet. Being that Earth’s troposphere is between 23, and 65, feet — depending on the season and latitude, at least — this means that commercial jets are almost always within the troposphere. The only exception is when a commercial jet is taking off or landing, in which . Cabin pressurization is a process in which conditioned air is pumped into the cabin of an aircraft or spacecraft in order to create a safe and comfortable environment for passengers and crew flying at high altitudes. For aircraft, this air is usually bled off from the gas turbine engines at the compressor stage, and for spacecraft, it is carried in high-pressure, often cryogenic tanks. The center of gravity (CG) of an aircraft is the point over which the aircraft would balance. Its position is calculated after supporting the aircraft on at least two sets of weighing scales or load cells and noting the weight shown on each set of scales or load cells. The center of gravity affects the stability of the aircraft. To ensure the aircraft is safe to fly, the center of gravity must.
