For those like me who are not familiar with aviation topics, "bleed air" is air taken from the compressor stage of the engines and used to pressurize the cabin. Not all aircraft use this system and some have an option to use this or some other system to pressurize cabin air.
- tavert 9y agoThe 787 is the only jet-powered passenger aircraft I'm aware of that doesn't use a bleed air system. Any pressurized-cabin turboprop aircraft uses bleed air, and so does the M1 Abrams tank. Bleed air is not just used for cabin pressurization, it's also used for anti-icing systems, cabin temperature control (the high-pressure air is the working fluid, see https://en.wikipedia.org/wiki/Air_cycle_machine https://en.wikipedia.org/wiki/Air_cycle_machine), and nitrogen generation systems for fuel tank inerting. (I worked on the environmental control system for the Gulfstream G650 many years ago)
