FLUID LEVEL CHECKThe following Aircraft Configuration is needed for a correct fluidlevel check and servicing:- the speed brakes and spoilers must be retracted,- the thrust reversers stowed, - the cargo doors closed,- all system accumulators empty of fluid and pressurized with nitrogento the correct pressure,- the accumulators pre-charge pressure must be checked,- the reservoirs are pressurized with air,- the landing gear must be in down position with the landing geardoors closed (one door may be open),- and the brake accumulator may be pressurized with fluid.
