Many modern aircraft are equipped with a Ram Air Turbine (RAT), a small, deployable device that can generate emergency power. In the rare event of a total power loss, the RAT pops out into the airstream, using the plane's forward motion to spin a turbine and provide vital systems with electricity, ensuring safety even in extreme situations. This backup feature underscores the incredible engineering focus on redundancy and resilience in aviation design. Have you come across any other fascinating aviation safety features?
