From 8,000 to 23,000 feet, what is the target pressure setting?

• A. 8k ± 1k
• B. Ambient
• C. 6k ± 2k
• D. 10k ± 1k

Answer: (A)

Maintaining comfortable and safe cabin conditions hinges on the cabin pressure altitude the system targets. For operations in the 8,000 to 23,000-foot range, the goal is to hold the cabin at about 8,000 feet, with a tolerance of roughly ±1,000 feet. This keeps the pressure differential within limits and minimizes passenger discomfort while balancing the aircraft’s structural requirements. So the best match is a target around 8,000 feet with a small allowable variance. Matching ambient would mean no pressurization at all, which isn’t acceptable at these cruise altitudes. Targeting 6,000 ± 2,000 could drift too low or too high for this flight segment, and 10,000 ± 1,000 would keep the cabin higher than typical for comfort and standard practice in this altitude band.
