temperature are at a maximum. At times it may be necessary to cool this high-pressure air. If it is used for cabin pressurization or other purposes to which excess heat would be uncomfortable or detrimental, the air is sent ... utilized in a wide variety of ways. Some of the current applications of bleed air are: 1. Cabin pressurization, heating, and cooling; 2. Deicing and anti-icing equipment…
- Chapter 16: Cabin Environmental Control Systems › Control of Cabin Pressure › Cabin Pressure Controller
Cabin Pressure Controller The cabin pressure controller is the device used to control the cabin air pressure. Older aircraft use strictly pneumatic means for controlling cabin pressure. Selections for the desired cabin altitude, rate of cabin altitude change, and barometric ... pressure setting are all made directly to the pressure controller from pressurization panel in the flight deck. [Figure 16-51] Adjustments and settings on the pressure controller are the control input parameters for the cabin pressure regulator. The regulator controls…
- Chapter 3: Induction & Exhaust Systems › Supercharged Induction Systems › Variable Absolute Pressure Controller (VAPC)
Variable Absolute Pressure Controller (VAPC) The VAPC contains an oil control valve similar to the other controllers that were discussed. [Figure 3-21] The oil restrictor is actuated by an aneroid bellows that is referenced to upper deck pressure ... connected to the throttle mechanism applies pressure to the restrictor valve and aneroid. As the throttle is opened to greater values, the cam applies a greater pressure to the aneroid. This increases the amount of upper deck pressure necessary…
