How many feet are added to cabin altitude to readjust for a High Alt mode warning light?

• A. 1000 ft
• B. 1200 ft
• C. 1550 ft
• D. 2000 ft

Answer: (C)

The correct answer is based on the standard procedures regarding cabin altitude management in aircraft systems. When a High Altitude warning appears, the cockpit crew must take appropriate action to ensure passenger and crew safety. In such situations, it is standard protocol to add a specific amount of altitude to the cabin altitude reading to account for the discrepancy and to correct for the sudden changes that can occur during flight. The typical adjustment is set to 1550 feet. This figure allows for margin in the cabin altitude warning checks, ensuring that the altitude remains within safe operational limits and that all systems are functioning correctly. Through this approach, pilots can effectively manage cabin pressures and maintain the safety of all onboard, as well as operate the aircraft confidently within established safety parameters.
