Airplane is more efficient in what altitude?

High altitude.

If an airplane is flown at this altitude, it consumes less fuel for a given airspeed than it does for the same speed at a lower altitude.

high altitude.

It permits a reasonably fast exchange of air from the inside to the outside of the cabin. This is necessary to eliminate odor and to remove stale air.

pressurization system.

Pressurization of the airplane cabin is an accepted method of protecting occupants against the effect of

hypoxia.

It maintains a cabin pressure altitude of approximately ______ at the maximum designed cruising altitude of the airplane, and prevents rapid changes of cabin altitude that may be uncomfortable or cause injury to passengers and crew.

8,000 ft

It may be used on older model turbine powered airplanes to pump air into the sealed fuselage.

superchargers.

Air is released from the fuselage by a device called _______. and it controls the pressurization system.

outflow valve.

the actual height above sea level at which the airplane is flying.

aircraft altitude.

The temperature in the area immediately surrounding the airplane.

ambient temperature.

The pressure in the area immediately surrounding the airplane.

ambient pressure.

It is used to express cabin pressure in terms of equivalent altitude above sea level.

cabin altitude.

The difference in pressure between the pressure acting on one side of a wall and the pressure acting on the other side of the wall. In aircraft air-conditioning and pressurizing systems, it is the difference between cabin pressure and atmospheric pressure.

differential pressure.

It is defined as the ability of the airplane's pressurization system to maintain its designed pressure differential. This can be caused by a malfunction system or structural damage to the airplane.

decompression.

It is defined as a change in cabin pressure faster than the lungs can decompress; therefore, it is that lung damage may occur.

explosive decompression.

The time required to release air from the lungs without restrictions, such as masks, is ______.

0.2 seconds.

It is considered as explosive and potentially dangerous if any decompression occurs in less than ______

0.5 seconds.

It is defined as a change in cabin presssure where the lungs can decompress faster than the cabin.; therefore, there is no likelihood of lung damage.

rapid decompression.

The primary danger of decompression is

hypoxia.

Pressurization systems are designed to keep the interior cabin pressure between how many psi at cruise altitude?

12 and 11 psi.

It is installed to protect the aircraft from over pressurizing.

positive pressure relief valves.

These devices are spring-loaded to vent excess air pressure when cabin pressure exceeds the maximum limit.

butterfly valves.

The pressure outside the cabin is greater than the pressure inside the cabin.

negative pressure differential relief doors.

This system is fundamentally comprised of air conditioning packs, a pack of flow control valve, a by-pass valve, pack controllers, and a mixing unit.

air conditioning system.

This system directs the conditioned air from the air conditioning system to the flight and passenger compartments.

air distribution system.

It controls the air temperature in the flight and passenger compartments.

temperature control.

It supplies clean fresh air to the flight and passenger compartments. Two air conditioning units are provided to decrease rhe temperature of the air from pneumatic system, and to remove water from the air.

cooling system.

It is used to cool the air conditioning units and may also be used to supply emergency air to the distribution system if the air conditioning units are not operating.

ram air.
