Let me show you how to replace and test Ram Air Turbine on A320.
In an emergency the Blue auxiliary system supplies hydraulic power to the aircraft. Electrical power can also be supplied through the Blue auxiliary system by the constant speed motor generator (CSMG). The system supplies hydraulic power in less than 4.5 seconds from the time it gets the electrical command to extend the RAT. The hydraulic power available from the RAT is sufficient to supply the flight controls and the CSMG (for electrical power). The RAT is available and will operate through the entire flight envelope. The RAT has a stall protection device which prevents a RAT stall below the governed speed range. The stall protection device limits the maximum power the pump can take from the turbine. When the stall protection device is in operation, the pump displacement is adjusted to get a constant RAT speed not related to the aircraft speed.
