Why are balance tabs installed on the aircraft's wings?

• A. To stabilize the aircraft in turbulence
• B. To reduce the pilot effort needed to move the ailerons
• C. To enhance aerodynamic efficiency
• D. To improve fuel efficiency

Answer: (B)

The installation of balance tabs on an aircraft's wings serves a specific purpose related to the control surfaces, particularly the ailerons. These tabs are small aerodynamic surfaces that are offset from the main control surface. Their primary function is to assist the pilot by reducing the control force required to move the ailerons. When a pilot wants to roll the aircraft by deflecting the ailerons, the balance tabs create a counteracting aerodynamic force that alleviates some of the pressure needed on the control yoke or stick. This reduction in control force contributes to a more manageable and responsive handling of the aircraft, especially during critical flight phases such as takeoff and landing. While the other options address different aspects of operational efficiency or performance, the main intention behind balance tabs is directly tied to pilot workload and ease of control—thereby making option B the most accurate choice concerning their purpose.
