would never imagine that the AIRBUS designer's would have had to add accu,ulators for energy storage - seems like the spoiler system is under sized ? Is this the way Lockheed did it on the L1011 ? - Boeing would never carry accumulators around for this purpose - Opps - Boeing does have a pyrotechnic actuator on the spoilers that are in the path of the overwing escape slide on the 777 & 767 ( I think ) - IE to fair the spoilers following an unscheduled incident - but this thing is tiny & uses the bleed fluid from the host system ..
