The 787s internal cabin pressure is the equivalent of 6000 feet 1800 m altitude resulting in a higher pressure than for the 8000 feet 2400 m altitude of older conventional aircraft.
787 cabin pressure. Typical passenger aircraft keep the cabin pressure at the equivalent of anywhere between 6000 feet and 8000 feet above sea level or the elevation of machu picchu. 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 altitudesfor 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. This is basic science. Ive asked this question before and apparently the engineers have decided that using generator power to run the cabin environmental systems represents a net savings in energy thats worth the doing.
The 787 will operate with a higher cabin pressure giving passengers the feeling of being at 6000 feet above sea level rather than the 8000 feet for other airliners. Anywhere above 8000 feet passengers begin to feel the effects of altitude sickness and lack of oxygen which could ultimately prove fatal. According to boeing in a joint study with oklahoma state university this will significantly improve passenger comfort. If cabin pressure is lower than the ground pressure trapped inside the bottle than it will expand.
In a move to make air transit more pleasant companies like boeing are designing new airplanes that are strong enough to sustain lower cabin pressures at high elevation without risking structural damage.
