What is the typical maximum cabin altitude used on the ERJ-175?

• A. Ten thousand feet
• B. Approximately 8,000 feet
• C. Six thousand feet
• D. Nine thousand feet

Answer: (B)

Cabin altitude is the effective altitude inside the airplane that the pressurization system maintains. For the ERJ-175, the system is designed to keep the cabin at about eight thousand feet during cruise. This level provides passenger comfort and safety while staying within the aircraft’s structural and systems limits. So, the typical maximum cabin altitude used on the ERJ-175 is around eight thousand feet. The other values would place the cabin either noticeably lower or higher than what this aircraft’s pressurization design targets, which is not aligned with how it’s intended to operate.
