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.
