Question 1: What method is typically used to determine the aerodynamic stability of an aircraft during high-speed flight?

Which action should you take?

Choose only one option

Nonlinear stability analysis

The method of load distributions and shear force analysis

Computational fluid dynamics simulations

Linearized stability analysis

Question 2: What is the primary benefit of using finite element analysis (FEA) in the design of aircraft structures?

Which action should you take?

Choose only one option

It provides a quick estimate of component weight without accurate modeling

It allows for detailed simulations of stress, strain, and thermal effects on the structure to optimize design

It reduces the need for testing and validation of prototypes

It guarantees that designs will perform perfectly in all conditions

Question 3: What is the role of "winglets" in the structural design of an aircraft's wings?

Which action should you take?

Choose only one option

Winglets increase the lift produced by the wing

Winglets increase the structural load on the wing, enhancing durability

Winglets reduce drag and improve fuel efficiency by mitigating vortex drag at the wingtip

Winglets enhance the aesthetic appeal of the aircraft

Question 4: In electrical systems design, why is redundancy critical in the power distribution network of a commercial aircraft?

Which action should you take?

Choose only one option

To enhance the aesthetic appeal of the aircraft interior

To reduce the overall cost of electrical systems

To ensure continuous operation of critical systems in case of a failure

To minimize the weight of the aircraft

Question 5: What is the relationship between drag coefficient and Reynolds number in the design of aircraft components?

Which action should you take?

Choose only one option

The drag coefficient is not affected by the Reynolds number

The drag coefficient decreases as Reynolds number increases

The drag coefficient increases with the Reynolds number at high speeds

The drag coefficient is inversely proportional to the Reynolds number

Question 6: How does the pressure distribution over an aircraft wing affect its lift generation?

Which action should you take?

Choose only one option

Decreases lift without increasing drag

Reduces drag while increasing lift

Increases the lift-to-drag ratio

Increases stability and reduces drag
