When initiating a power-on stall, what action is taken after reaching 65 KIAS?

When initiating a power-on stall maneuver, the correct action after reaching 65 KIAS is to increase the throttle to a specified value, often around 2000 RPM. This is essential for simulating a scenario where the aircraft is in a climbing flight situation with power applied. By ensuring that the engine maintains a certain level of thrust, you can replicate the conditions that lead to a stall while also making sure that the wings are still producing lift due to the airflow over them.

Increasing the throttle sets up the aircraft to maintain climb performance until the stall is reached, allowing for a more accurate assessment of stall characteristics under power. The increased power helps to keep the aircraft in a controlled state as it approaches the stall, providing valuable insights into handling characteristics during such critical phases of flight.

In contrast, reducing throttle, extending flaps, or pitching the nose down would not effectively prepare the aircraft for experiencing a power-on stall, as these actions may alter the dynamics necessary to execute the maneuver correctly.
