What is a Pressurised Cabin?
Cabin pressurization is the active pumping of air into the cabin of an aircraft to increase the air pressure within the cabin. It is required when an aircraft reaches high altitudes and the outside air becomes thinner, containing less oxygen. All airliners, jets and turboprops have pressurised cabins. Only smaller air taxis are unpressurised, and may only operate at altitudes of up to 10,000 ft (3000m). Flying at lower altitudes can be a wonderful experience. On a clear day, you can enjoy the scenery; you can see the towns, cities, roads, mountains, lakes, and rivers. Due to their altitude restriction, unpressurised aircraft have to fly around, rather than over the weather.
