HYDRAULIC MENU System presentation 1/19 HYDRAULIC MENU System presentation 2/19 The A320 family has three independent hydraulic systems : - GREEN, -- YELLLLOW,, - and BLUE. Now, let’s look at the systems in more detail. HYDRAULIC MENU System presentation 3/19 The GREEN and YELLOW hydraulic systems are each pressurized by an engine driven pump.

HYDRAULIC MENU System presentation 11/19 Let’s briefly review the basic system using the ECAM HYDRAULIC page. . The reservoirs, . The fire shut-off valves, HYDRAULIC MENU System presentation 12/19 . The pumps, . The RAT, HYDRAULIC MENU System presentation 13/19 . The PTU, . The pressure indications. HYDRAULIC MENU System presentation 14/19 The controls for the components that we have introduced are located on the overhead hydraulic control panel. Let’s now go to the ECAM HYD page together with the hydraulic control panel. HYDRAULIC MENU System presentation 15/19 The hydraulic system is fully automatic. However each pump and the PTU have an associated pushbutton switch for abnormal operation. HYDRAULIC MENU System presentation 16/19 Each hydraulic engine pump is controlled by a pb sw located on the overhead panel.
