1) The rate of flow of air from the punkha louvers should not be less than Report

300 ft/min.

200 ft/min.

25 ft/min.

2) An aircraft cabin is air conditioned and pressurized in order to Report

maintain human efficiency and comfort during flights at high altitudes

ensure that the pressure within the fuselage is always less than the ambient pressure, thus increasing the fatigue life of the fuselage

ensure that the air density within the cabin is maintained at a lower figure than outside the cabin in order to prevent moisture precipitation during rapid decompression

3) If the pilot selected a cabin height of 8000 ft. whilst taxiing and activated the pressurization system, the cabin pressure would Report

decrease to a pressure equivalent to about 500 ft

remain at ground level pressure

decrease to a pressure equivalent to 8000 ft

4) A silencer is installed in a pressurization system to reduce Report

the noise from the high speed of airflow within the system

engine noise coming through the ventilators

the noise from the blowers and/or compressors in the system

5) To avoid discomfort, the rate of change of pressure should be low, particularly Report

when cabin pressure is decreasing

during descent

during ascent
