2 HYDRAULIC SYSTEM
第四部分里面有一张图是关于hydraulic system的，建议这个系统多熟悉一下
Units commonly operated by hydraulic system :
Landing gears , wing flaps , slats , speed and wheel brakes , nose wheel steering ,
Primary flight surfaces

hydraulic system components:
an engine driven pump , a filter , a reservoir , a pressure regulator , an accumulator ,
a pressure gauge , a relief valve , an emergency pump , two check valves ,
a selector valve , an actuating cylinder

operation
the engine driven pump which is directly coupled to the engine will operate when the engine is running. The pump draws fluid from reservoir and expe
ls to the system through the filter and a check valve and the pressure can be built up. the pressure regulator unloads or relieves the engine driven pump when the desired pressure in the system achieved . thus it’s often referred to as an unloading the event of malfunction of pressure regulator , the relief valve will release any pressure above that maintained by the regulator.

3 AIR CONDITIONING AND PRESSSURIZATION SYSTEM
The cabin air conditioning and pressurization system supplies conditioned air for heating and cooling the cockpit and cabin spaces. This air also provides pressurization to maintain a safe and comfortable cabin environment. Some of the air conditioning systems installed in modern aircraft utilize air turbine refrigerating units to supply cooled air. These are called air cycle system.
Function of air conditioning system:
To maintain a comfortable temperature within the fuselage. In a typical syst
