Which of the following scenarios can lead to a stall in a PPC wing?

• A. Flying with a well-rigged wing
• B. A gradual increase in throttle
• C. Improper rigging and not inspecting the wing
• D. Maintaining a constant angle of attack

Answer: (C)

A stall in a PPC wing occurs when the airflow over the wing becomes insufficient to maintain flight due to an excessive angle of attack. Proper rigging and regular inspection of the wing are crucial for ensuring optimal performance and stability. If the wing is improperly rigged or not inspected, it may not be able to generate the necessary lift, particularly during maneuvers that increase the angle of attack, leading to a stall. In contrast, a well-rigged wing ensures that the aircraft behaves predictably, while a gradual increase in throttle helps maintain control and lift, reducing the risk of a stall. Similarly, maintaining a constant angle of attack within the aircraft's operating limits is essential for safe flight, as it helps to prevent the conditions that could lead to a stall. Therefore, the scenario of improper rigging and failure to inspect the wing creates an environment conducive to a stall by compromising the wing's performance characteristics.
