What is “Ram Air Turbine”?

by Captain Joe

What is the ram air turbine, or better known as the RAT?

We’ll be looking at some basic system knowledge on the Airbus Hydraulics (the green, blue and yellow system) and then dive straight in to an ELEC EMER CONFIG.

You will see how the ram air turbine is deployed and I’ll go into more detail about the ram air turbine duties.

We will use a AC BUS 1&2 FAULT as a primary example and how the RAT produces electricity.

And the second scenario will be a DUAL ENGINE FAILURE, and how the RAT provides electrical power plus hydraulic power to be able to control the aircraft in such an emergency event.
