Which prevents a sudden loss of pressurization in the event that there is a loss of the pressurization source?

  1. Outflow valve

  2. Cabin pressure controller

  3. Delivery air duct check valve

  4. Negative pressure relief valve

The correct answer is: Delivery air duct check valve

The correct answer is the delivery air duct check valve because it prevents a sudden loss of pressurization in the event of a loss of the pressurization source. This valve is designed to prevent the backflow of air from the cabin to the source, ensuring that the pressurized air remains contained within the aircraft cabin. The outflow valve, cabin pressure controller, and negative pressure relief valve do play important roles in the pressurization system, but they do not specifically prevent a sudden loss of pressurization in the event of a loss of the pressurization source.
