kabineluchtniveau

Kabineluchtniveau is a Dutch term that refers to the level of air within a vehicle cabin, focusing on environmental conditions such as air pressure, temperature, humidity, and air quality. In aviation it is most often used to describe the cabin pressure level, or cabin altitude, which is the effective altitude inside the cabin produced by the pressurization system. Maintaining a stable kabineluchtniveau is essential for comfort and safety during flight.

The cabin environment is produced by the environmental control system (ECS), which mixes conditioned air from bleed air or electric compressors with recirculated cabin air, filters it with HEPA filters, and regulates temperature and humidity. A cabin altitude of about 6,000 to 8,000 feet is typical for commercial airliners, while outside cruising altitude may exceed 30,000 feet. Relative humidity in cabins is low, often 4–12%, and CO2 levels are monitored and kept within safe limits.

In practice, the term is mainly used in aviation but may also be applied to other cabins such as trains or ships. Differences between vehicle types lead to variations in maximum differential pressure and humidity. Understanding kabineluchtniveau helps airlines plan passenger comfort, crew performance, and safety procedures in pressurized cabins.
