What type of air does the compression section provide?

Explanation:
Bleed air is the air taken from the compressor section of the engine. It’s high-pressure, high-temperature air routed to the aircraft’s pneumatic systems—primarily the environmental control system (air conditioning and cabin pressurization), anti-icing, and sometimes starting air for engines or the APU. Because it comes from the compressor rather than outside, it’s not fresh air. Combustion air is the air fed to the engine’s burners, and “cool air” isn’t a separate source used for these systems; the bleed air is conditioned as needed before use.
