Long Quiz Flashcards
This special container is used to store and transport liquid oxygen. It uses an evacuated, doublewalled insulation design to keep the liquid oxygen under pressure at a very low temperature.
DEWAR BOTTLE
are adjusted by the crew as altitude changes.
MANUAL CONTINUOUS FLOW REGULATORS
the difference between the air pressure inside the cabin and the air pressure outside the cabin.
CABIN DIFFERENTIAL PRESSURE
the rate of change of air pressure inside the cabin, expressed in feet per minute (fpm) of cabin altitude change.
CABIN RATE OF CLIMB
using a Barometer, what is the atmospheric pressure at sea level?
14.7 PSI
Are driven by engine exhaust gases. They are the most common source of pressurization on modern reciprocating engine aircraft.
TURBOCHARGER
What drives the turbo-compressor on turbine engines?
BLEED AIR
is mechanically driven by the engine. Despite engine performance increases due to higher induction system pressure, some of the engine output is utilized by this.
SUPERCHARGER
A (?) setup for a light aircraft exemplifies this type of continuous-flow system.
PORTABLE OXYGEN
this is part of the exhaust system that drives an impeller connected to a shaft that sucks air used for combustion/pressurization.
SUPERCHARGER
must also be heated or cooled on pressurized aircraft.
CABIN AIR
What will happen to the pressure if the temperature decreases?
DECREASES
Bad weather and turbulence can also be avoided by flying in the relatively smooth air above storms and convective activity that occur in the (?).
LOWER TROPOSPHERE
Smaller turbine aircraft, or sections of a large aircraft, may make use of a (?). With this device, bleed air is tapped off of the turbine engine’s compressor section.
JET PUMP FLOW MULTIPLIER
This system is used most frequently by the crew on high performance and air transport category aircraft.
DEMAND FLOW SYSTEM
This system must accomplish several functions if it is to ensure adequate passenger comfort and safety.
CABIN PRESSURIZATION SYSTEM
is also Known as barometric pressure and is measured with a barometer.
ATMOSPHERIC PRESSURE
what is the height of mercury at sea level?
29.92 INCHES
What will happen to the temperature if the pressure increases?
INCREASES
A turbine turned by bleed air rotates a compressor impeller mounted on the same shaft. Outside air is drawn in and compressed. It is mixed with the bleed air outflow from the turbine and is sent to the pressure vessel. Turboprop aircraft often use this device, known as a?
TURBO COMPRESSOR
When ignited, it produces oxygen as it burns. This can be filtered and delivered through a hose to a mask that can be worn and breathed directly by the user.
SODIUM CHLORATE
A key factor in (?) is the ability of the fuselage to withstand the forces associated with the increase in pressure inside the structure versus the ambient pressure outside.
PRESSURIZATION
is tested for the presence of water. This is done to avoid the possibility of it freezing in the small passage ways of valves and regulators.
AVIATOR’S BREATHING OXYGEN
is a colorless, odorless, and tasteless gas at normal atmospheric temperatures and pressures. It transforms into a liquid at -183 °C (its boiling point).
