Which of the following is a sign of an impending stall?

• A. Excessive cockpit noise
• B. Whiteout conditions outside
• C. Change in control response
• D. Decreased engine performance

Answer: (C)

A change in control response is an important indicator of an impending stall because it suggests that the airflow over the wings is beginning to separate, which is a critical precursor to a stall. Pilots rely on the feel of the aircraft as they manipulate the controls, and when the aircraft approaches a stall, the controls may feel different—often mushier or less responsive. This change serves as a vital cue, prompting the pilot to take corrective action to prevent an actual stall. Excessive cockpit noise does not directly relate to an approaching stall. While certain noises can indicate other mechanical issues or turbulence, they are not definitive indicators of stall behavior. Whiteout conditions outside refer to visual impairments caused by snow, fog, or other atmospheric effects. While these conditions can complicate flying, they do not serve as a specific sign of an impending stall. Decreased engine performance might indicate other issues such as fuel starvation or mechanical failure, but it is not a sign of an aircraft approaching a stall condition. Rather, stalls are primarily related to aerodynamic factors over engine performance.
