To clear a compressor stall, what airspeed range should be maintained during level flight?

To clear a compressor stall, what airspeed range should be maintained during level flight?

• A. 50-60 KIAS
• B. 60-70 KIAS
• C. 70-80 KIAS
• D. 80-90 KIAS

Answer: (B)

Maintaining an airspeed within the range of 60-70 KIAS during level flight is crucial for effectively clearing a compressor stall in the TH-73A. This specific airspeed range allows for a balance between providing sufficient airflow through the engine and minimizing the possibility of further stall conditions, ensuring that the compressor can regain stable operation. Flying at this airspeed helps to enhance the inlet airflow, which is essential to prevent compressor stall conditions from reoccurring after the initial stall has been cleared. Furthermore, this range allows for optimal control and responsiveness of the aircraft, facilitating pilot recovery actions and stabilization. In contrast, flying at speeds below this range may result in inadequate airflow, prolonging the stall, while speeds significantly higher than this range could induce excessive stress on the engine and airframe, further complicating recovery efforts.
