Question: 1 / 1030

What is the primary purpose of stall strips on airplane wings?

Stall the inboard portion of the wings first

Stall strips are small devices attached to the leading edge of an airplane wing, and their purpose is to delay the stall of the wing by successfully aerodynamically disrupting the airflow over the wing. This allows for the inboard portion of the wings to stall first, which is beneficial in the event of a stall as it keeps the ailerons (located on the outboard portion of the wings) functional for control. Options B, C, and D are incorrect as they do not adequately describe the primary purpose of stall strips. While stall strips may indirectly contribute to these factors, they are not the main reason why they are installed on airplane wings.
