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…
- Chapter 8: Flight Instruments › Impact Pressure Chamber and Lines
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 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 8: Flight Instruments › Blocked Pitot System
change is not related to a change in airspeed but a change in static pressure. The total pressure in the pitot tube does not change due to the blockage; however, the static pressure will change. Because airspeed indications rely upon ... both static and dynamic pressure together, the blockage of either of these systems affects the ASI reading. Remember that the ASI has a diaphragm in which dynamic air pressure is entered. Behind this diaphragm is a reference pressure called static…
- 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…

Figure 10-20. A pressure switch can be used in addition to, or instead of, a pressure gauge. A low oil pressure indication switch is a common example of how pressure switches are employed. It is installed in an engine ... pressurized oil can be applied to the switch’s diaphragm. Upon starting the engine, oil pressure increases and the pressure against the diaphragm is sufficient to hold the contacts in the switch open. As such, current does not flow through…
