The Engine 2 was shut down. Part of the damage caused Engines 1 & 4 to go into a ‘degraded’ mode. The engines were still operating and Engine 3 was the only engine that was operating normally. Basically, dealing with all those things took some time, then the next series of messages were hydraulic problems. We had indications that the green hydraulic system was losing all its fluid. The Airbus A380 carries two and, unlike most conventional aeroplanes, most flying surfaces aren’t powered by hydraulics, they have their own electric-hydraulic actuators. There is a green and yellow system and they spilt their duties between things like brakes, undercarriage retraction/extension. With the green system out we had to deploy the nose gear and body gear using the gravity extension system. With the loss of the green system we dealt with that and curiously we had the hydraulic pumps of Engine 4 indicating failed as well. Engine 3, the trusty engine, was the only engine that was producing hydraulics for the aircraft for the yellow system.
