Title: Explain the aircraft pressurization system.
Course: Aircraft Pilot Training I (20053-I) > Section: Examining Aircraft Instruments, Components, Systems, and Performance

Explanation should include the following:

- A cabin pressurization system typically maintains a cabin pressure altitude of approximately 8,000 feet at the maximum designed cruising altitude of an aircraft.
- This prevents rapid changes of cabin pressure altitude that may be uncomfortable or cause injury to passengers and crew.
- The pressurization system permits a reasonably fast exchange of air from the inside to the outside of the cabin.
