Determine the corrections or otherwise of the following assertion [A] and reason [R]:Assertion [A]: Fuel consumption is more for low level, high speed flight mission.Reason[R]: At low altitude, the aerodynamic efficiency decreases drastically which affects the engine efficiency and range as well. To maintain cruise flight more fuel consumption is required. |
A. | Both [A] and [R] are true and [R] is the correct reason for [A] |
B. | Both [A] and [R] are true but [R] is not the correct reason for [A] |
C. | [A] is true but [R] is false |
D. | [A] is false but [R] is true |
Answer» B. Both [A] and [R] are true but [R] is not the correct reason for [A] | |
