View Answer

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.

Options

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

View Answer

Determine the corrections or otherwise of the following Assertion [A] and reason [R]:^ Assertion [A]: Total fuel volume of aircraft is divided into mission or used fuel, reserve fuel and trapped fuel.^ Reason[R]: Depending on type of aircraft, fuel fraction for each category will be different.

Options

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

View Answer

In A/C, we provide reserve fuel for ___

Options

A : loiter maneuver

B : weight reduction

C : to increase weight

D : there is no provision for it
