What is the typical cabin pressurization altitude during cruise on a 737-800?

The typical cabin pressurization altitude during cruise for a Boeing 737-800 is generally set to around 6000 to 8000 feet. This range is chosen to balance passenger comfort and aircraft performance during flight.

Pressurizing the cabin to this altitude allows for an optimal balance between reducing the risk of decompression sickness and ensuring sufficient oxygen levels for passengers and crew. Maintaining cabin altitude within this range minimizes fatigue for passengers and enhances overall comfort during a flight, which is a key consideration for commercial airlines like Ryanair.

Additionally, this pressurization setting corresponds to the aircraft's operational limits and capabilities, ensuring that structural integrity is maintained while maximizing efficiency in terms of fuel consumption, which is crucial for low-cost carriers. By maintaining the cabin pressure at this level, airlines strike a balance between safety, comfort, and operational efficiency, making it the standard for many aircraft, including the 737-800.
