Question 3: What is the effect of the aspect ratio of a wing on the aircraft's performance?

Which action should you take?

Choose only one option

A lower aspect ratio is ideal for supersonic flight

Aspect ratio does not significantly affect aircraft performance

A higher aspect ratio improves lift and reduces drag at subsonic speeds

A higher aspect ratio reduces lift but improves stability at high speeds

Question 4: Which design consideration is crucial when designing for high-speed flight in aerospace structures?

Which action should you take?

Choose only one option

Increases structural flexibility

Optimizes fuel efficiency
