What is the purpose of the RAM AIR system?

• A. To pressurize the cabin during climb
• B. To provide emergency oxygen
• C. To ventilate the cockpit and the cabin when unpressurized and no packs are operating.
• D. To cool the flight deck continuously

Answer: (C)

RAM AIR provides ventilation air for the cockpit and cabin when the normal environmental control system isn’t supplying conditioned air—specifically during unpressurized flight and when the packs are not operating. Opening the ram air path brings outside air into the ducts to ventilate occupants and help prevent overheating of equipment. It does not pressurize the cabin, it does not supply emergency oxygen, and it is not used for continuous cooling when packs are on.
