addition, the pressurization system permits a reasonably fast exchange of air from the inside to the outside of the cabin. This is necessary to eliminate odors and to remove stale air. [Figure 7-41] Pressurization of the aircraft cabin ... necessary in order to protect occupants against hypoxia. Within a pressurized cabin, occupants can be transported comfortably and safely for long periods of time, particularly if the cabin altitude is maintained at 8,000 feet or below, where…

Impact Pressure Chamber and Lines The pitot tube is utilized to measure the total combined pressures that are present when an aircraft moves through the air. Static pressure, also known as ambient pressure, is always present whether an aircraft ... moving or at rest. It is simply the barometric pressure in the local area. Dynamic pressure is present only when an aircraft is in motion; therefore, it can be thought of as a pressure due to motion. Wind also generates…
- Chapter 7: Aircraft Systems › Oxygen Systems › Pressure-Demand Oxygen Systems
Pressure-Demand Oxygen Systems Pressure-demand oxygen systems are similar to diluter demand oxygen equipment, except that oxygen is supplied to the mask under pressure at cabin altitudes above 34,000 feet. Pressure-demand regulators create airtight and oxygen-tight ... seals, but they also provide a positive pressure application of oxygen to the mask face piece that allows the user’s lungs to be pressurized with oxygen. This feature makes pressure demand regulators safe at altitudes above 40,000 feet…
- Chapter 8: Flight Instruments › Static Pressure Chamber and Lines
Many aircraft have pitot tube covers installed when they sit for extended periods of time. This helps to keep bugs and other objects from becoming lodged in the opening of the pitot tube. The one instrument that utilizes the pitot ... tube is the ASI. The total pressure is transmitted to the ASI from the pitot tube’s pressure chamber via a small tube. The static pressure is also delivered to the opposite side of the ASI, which serves to cancel…
- 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 10: Aircraft Systems › Pressure Measuring Instruments › Types of Pressure
Many aircraft instruments make use of absolute pressure values, such as the altimeter, the rate-of-climb indicator, and the manifold pressure gauge. As stated, this is usually done with an aneroid. The most common type of pressure measurement ... gauge pressure. This is the difference between the pressure to be measured and the atmospheric pressure. The gauge pressure inside the deflated balloon is therefore 0 pounds per square inch (psi) because the pressure inside the balloon is equal…
