Abstract: A aircraft braking system is disclosed including a plurality of brakes each for braking one of a plurality of aircraft wheels using hydraulic pressure, a first hydraulic pressure supply unit, and a second hydraulic pressure supply unit. The first hydraulic pressure supply unit is connected to only a first subset of the plurality of brakes, such that the first hydraulic pressure supply unit can enable only the first subset of the plurality of brakes to provide braking. The second hydraulic pressure supply unit is connected to only a second subset of the plurality of brakes, the second subset not including any of the brakes of the first subset, such that the second hydraulic pressure supply unit can enable only the second subset of the plurality of brakes to provide braking.

Abstract: A method for storing printing plates (4) in a stacker (5) comprises the steps of detecting a printing plate (8) exiting a processor (1) or exiting a baking station, activating a conveying mechanism (2) of a stacker, conveying (A) the printing plate to a rear side (18) of the stacker and deactivating the conveying mechanism when the printing plate reaches the rear side of the stacker. Then further steps comprise tilting (B) the printing plate by means of rotating tilting bars (6) into a plate trolley (5) and returning the tilting bars back to a home position (19) on the stacker. Herein, the tilting the printing plate comprises the substeps of releasing a forcing means from the stacker, and forcing (P) the printing plate away from the tilting bars against a rest position (21) in the trolley.
