Under what condition will a Powered Parachute wing stall?

• A. When the weather is calm
• B. When the critical angle of attack is exceeded
• C. When the PPC is flying below 1000 feet
• D. When the throttle is at maximum

Answer: (B)

A Powered Parachute wing will stall when the critical angle of attack is exceeded. The critical angle of attack is the angle at which the airflow over the wing can no longer remain attached, leading to a loss of lift. This can occur regardless of the conditions, such as whether the weather is calm or windy, and it is not specifically dependent on the altitude or throttle setting either. It’s important to recognize that stall behavior is primarily a function of the angle of attack. When the wing exceeds this angle, it can result in a stall, even if the power settings are maximized or if the aircraft is at a low altitude. Understanding the dynamics of stall is crucial for safe flight operations and is a key component of pilot training in maneuvering aircraft like powered parachutes.
