What is a primary benefit of dihedral wings in terms of aircraft handling?

• A. They provide roll stability in turbulent conditions
• B. They reduce overall lift
• C. They increase drag
• D. They help in directing airflow over the wings

Answer: (A)

The primary benefit of dihedral wings lies in their ability to enhance roll stability in turbulent conditions, which is crucial for maintaining a smooth and controlled flight path. When an aircraft with dihedral wings experiences a disturbance, such as turbulence, the wings cause the aircraft to naturally right itself. This occurs because when a wing drops due to turbulence, the lift vector shifts, resulting in additional upward lift on the higher wing. Consequently, this promotes stability and helps the aircraft return to a level flight attitude, enhancing overall handling characteristics. This phenomenon is particularly beneficial during flight operations that demand high levels of stability and control, making it advantageous for both general aviation and commercial aircraft designs. Other choices do not align with the benefits dihedral wings provide. Reducing overall lift and increasing drag are generally not associated outcomes of having a dihedral wing design, nor does it primarily aid in directing airflow over the wings as a main function. Thus, the stabilization effect in turbulence is the key advantage that dihedral wings offer in aircraft handling.
