Which statement about RAT deployment is true?

Which statement about RAT deployment is true?

• A. It will deploy automatically on total electrical power loss or dual engine failure
• B. It will deploy automatically on any loss of power without engine failure
• C. It requires manual command under all conditions
• D. It never deploys automatically

Answer: (B)

The thing being tested is how the Ram Air Turbine (RAT) behaves in power loss situations. The RAT is part of the emergency power system and is designed to extend automatically when the aircraft experiences a loss of power that could affect flight controls and essential systems. Its purpose is to provide hydraulic power (and some electrical power via its own hydraulic pump) so you can maintain control and operate critical systems while you handle the emergency. That’s why the best statement is that it will deploy automatically on any loss of power without engine failure. If power is lost and the engines are still healthy (or at least there isn’t a complete, engine-driven power loss), the RAT will extend automatically to ensure you have the necessary emergency power and hydraulic capability. The other options imply conditions that aren’t the sole triggers or require manual action all the time, or claim it never deploys automatically, which isn’t correct for the RAT’s intended automatic response in a loss-of-power scenario.
