EMERGENCY GENERATION AFTER LOSS OF ALL MAIN GENERATORS
If both the AC BUS 1 and AC BUS 2 buses are lost and the aircraft speed is above 100
knots, the Ram-Air Turbine (RAT) extends automatically. This powers the blue hydraulic
system, which drives the emergency generator by means of a hydraulic motor. This
generator supplies the AC ESS BUS, and the DC ESS BUS via the ESS TR.
If the RAT stalls or if the aircraft is on the ground with speed below 100 knots, the
emergency generator has nothing to drive it. The emergency generation network transfers
automatically to the batteries and static inverter, and the system automatically sheds the
AC SHED ESS and DC SHED ESS buses.
When the aircraft is on the ground :
- Below 100 knots the DC BAT BUS is automatically connected to the batteries.
- Below 50 knots the AC ESS BUS is automatically shed, leading to the loss of all CRTs.
