The jet aircrafts fly very easily and smoothly in the lower stratosphere. What could be the appropriate explanation? |
1. There are no clouds or water vapour in the lower stratosphere. |
2. There are no vertical winds in the lower stratosphere. |
Which of the statement(s) given above is/are correct? |
A) Only-1
B) Only 2
C) Both 1 and 2
D) Neither1nor 2
Correct Answer: C
Solution :
Exp. [c] Clouds and thunderstorms are dangerous to aircraft and water vapours and other weather phenomena causes changes in air density, which too is not optimal for flight. Most importantly a jet aircraft achieves most efficient flight in low density air. Vertical winds or convection currents due to weather activity causes turbulence which too is dangerous to flight. In normal circumstances, a jet aircraft will fly around a thunderstorm.You need to login to perform this action.
