Determine the corrections or otherwise of the following assertion and reason : Assertion : Typically control surface are tapered with same taper ratio as primary component such as wing or tail Reason: Control surface is used to provide trim control to the A/C and are true and is the correct reason for b) Both and are true but is not the correct reason for c) Both and are false d) is false but is true

Correct Answer: A
Control surface is used to provide control to the aircraft. In general, we provide same taper ratio to the control surface as wing or tail. By using same taper ratio we can ensure that constant percent chord is being maintained by the surface.

Determine the corrections or otherwise of the following assertion and reason : Assertion : Taper ratio will affect the weight of wing. Reason: For finite taper ratio, wing thickness will be different at root and tip. and are true and is the correct reason for b) Both and are true but is not the correct reason for c) is true but is false d) is false but is true

Determine the corrections or otherwise of the following assertion and reason : Assertion : Most of the tails are using symmetric airfoils. Reason: Tail control has two primary control surface. and are true and is the correct reason for b) Both and are true but is not the correct reason for c) is true but is false d) is false but is true

Determine the corrections or otherwise of the following assertion and reason : Assertion : In general, wing twist should not be more than 6°. Reason: Wing twist is used to improve stall properties at tip. and are true and is the correct reason for b) Both and are true but is not the correct reason for c) is true but is false d) is false but is true

Determine the corrections or otherwise of the following Assertion and Reason : Assertion : Total fuel CG is located near to the aircraft CG. Reason: Fuel can be located at centre, at tip or at tail. and are true and is the correct reason for b) Both and are true but is not the correct reason for c) is true but is false d) is false but is true

Determine the corrections or otherwise of the following assertion and reason : Assertion : Maintaining smooth longitudinal contour in fuselage will give better aerodynamic design. Reason: Longitudinal control lines are used to provide smoothness to the fuselage. and are true and is the correct reason for b) Both and are true but is not the correct reason for c) Both and are false d) is false but is true

Determine the corrections or otherwise of the following Assertion and Reason : Assertion : Typically, gun should be located away from the cockpit. Reason : Gun can induce sudden yawing. and are true and is the correct reason for b) Both and are true but is not the correct reason for c) is true but is false d) is false but is true

Determine the corrections or otherwise of the following assertion and reason : Assertion : Aerobatic prop aircraft has much higher power loading. Reason: Power loading of prop aircraft is ratio of power to the weight of the aircraft. and are true and is the correct reason for b) Both and are true but is not the correct reason for c) Both and are false d) is false but is true

Determine the corrections or otherwise of the following Assertion and reason : Assertion : Total fuel volume of aircraft is divided into mission or used fuel, reserve fuel and trapped fuel. Reason: Depending on type of aircraft, fuel fraction for each category will be different. and are true and is the correct reason for b) Both and are true but is not the correct reason for c) is true but is false d) is false but is true

Determine the corrections or otherwise of the following assertion and reason : Assertion : In modern A/C, we generally do not use spline lofting. Reason: Spline lofting is drawn through connecting different known points via spline line. and are true and is the correct reason for b) Both and are true but is not the correct reason for c) Both and are false d) is false but is true

Determine the corrections or otherwise of the following assertion and reason : Assertion : Fuel consumption is more for low level, high speed flight mission. Reason: 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. and are true and is the correct reason for b) Both and are true but is not the correct reason for c) is true but is false d) is false but is true
