- Chapter 7: Aircraft Systems › Pressurized Aircraft
order to fly at higher altitudes, the aircraft must be pressurized or suitable supplemental oxygen must be provided for each occupant. It is important for pilots who fly these aircraft to be familiar with the basic operating principles ... typical pressurization system, the cabin, flight compartment, and baggage compartments are incorporated into a sealed unit capable of containing air under a pressure higher than outside atmospheric pressure. On aircraft powered by turbine engines, bleed air from the engine compressor…
- Chapter 18: Emergency Procedures › In-Flight Fire › Cabin Fire
Cabin Fire Cabin fires generally result from one of three sources: (1) careless smoking on the part of the pilot and/or passengers; (2) electrical system malfunctions; or (3) heating system malfunctions. A fire in the cabin presents the pilot with ... fire and getting the airplane safely on the ground as quickly as possible. A fire or smoke in the cabin should be controlled by identifying and shutting down the faulty system. In many cases, smoke may be removed from…
- Chapter 11: Aircraft Performance › Atmospheric Pressure
Under standard conditions at sea level, the average pressure exerted by the weight of the atmosphere is approximately 14.7 pounds per square inch (psi). The density of air has significant effects on the aircraft’s performance. As air becomes less ... propeller is less efficient in thin air • Lift, because the thin air exerts less force on the airfoils The pressure of the atmosphere may vary with time but more importantly, it varies with altitude and temperature. Due to the changing…
- Chapter 12: Weather Theory › Wind and Currents › Wind Patterns
Wind Patterns In the Northern Hemisphere, the flow of air from areas of high to low pressure is deflected to the right and produces a clockwise circulation around an area of high pressure. This is known as anticyclonic circulation ... opposite is true of low-pressure areas; the air flows toward a low and is deflected to create a counterclockwise or cyclonic circulation. [Figure 12-10] High-pressure systems are generally areas of dry, descending air. Good weather is typically…
- Chapter 16: Cabin Environmental Control Systems › Control of Cabin Pressure › Cabin Air Pressure Safety Valve Operation
pressure regulating mechanism can also be found as a separate unit. Many air transport category aircraft have an outflow valve that operates electrically, using signals sent AUTO MANUAL FLT ALT ALTN LAND ALT from a remotely located cabin air pressure ... controller that acts as the pressure regulator. The controller positions the valve(s) to achieve the settings on the flight deck pressurization panel selectors according to predetermined pressurization schedules. Signals are sent to electric motors to move the valve…
- Chapter 16: Cabin Environmental Control Systems › Control of Cabin Pressure › Cabin Air Pressure Regulator & Outflow Valve
pressurization systems contain a manual mode that can override automatic control. This can be used in flight or on the ALT HORN CUTOUT ground during maintenance. The operator selects the manual mode on the pressurization control panel. A separate switch ... used to position the outflow valve open or closed to control cabin pressure. The switch is visible in Figure 16-53, as well as a small gauge that indicates the position of the valve. Cabin Air Pressure Regulator & Outflow Valve…
