What is the maximum operating altitude for the aircraft?

• A. 41,000 ft
• B. 40,000 ft
• C. 39,500 ft
• D. 42,000 ft

Answer: (A)

The highest altitude at which the airplane is certified to operate safely is determined by the limits of its structure, pressurization, and propulsion. For the ERJ 175, that certified ceiling is 41,000 ft. At 41,000 ft the aircraft can maintain proper cabin pressure differential and overall system performance within safe margins. Altitudes below are allowed but not the maximum, while anything above 41,000 ft is not permitted. So the maximum operating altitude is 41,000 ft.
