12-Temperature decreases with altitude in standard atmosphere. Regarding this change in temperature, density should increase with altitude but it decreases. What is the reason?

050 1

The increase in pressure with altitude decreases the density. The temperature has no effect on air density. The decrease in pressure being more dominant than the decrease in temperature, causes the density to decrease. Scientist continue their research on this subject

14-How does the temperature effect of on vertical pressure variation.

050 1

In warm air, the rate of pressure decrease with altitude is greater than in cold air. Warm air causes pressure to fall more rapidly with height. In cold air, the rate of pressure decrease with altitude is greater than in warm air. Cold air causes pressure to fall more slowly with height.

16-Mark the correct statement concerning the flight through an inversion caused by subsidence.

050 15859 Flight Hazards

During climb, the reduced air density above the inversion layer will cause a certain decrease in the aircraft performance (i.e. lift and thrust) and the pilot will experience a sudden improvement of visibility. The pilot of an aircraft probably will experience a gradual increase of the cross wind component and a gradual improvement of flight visibility when breaking through the base of the inversion layer during descent. During climb, the pilot of an aircraft probably will experience a slight deterioration of flight visibility when breaking through the top of the inversion layer and the general aircraft performance will decrease. During climb, the increased air density above the inversion layer will cause a certain increase in the aircraft performance (i.e. lift and thrust) and the pilot will experience a gradual change of the cross wind component.
