During which condition would the center of pressure typically move forward?

The center of pressure shifts forward primarily during low-speed flight due to the changes in the airflow characteristics around the aircraft. At lower speeds, the relative airflow tends to be more aligned with the wing's chord line, which enhances the lift produced by the wing and allows the center of pressure to move forward. This motion is a result of the increased angle of attack that typically occurs as the aircraft slows down, which can lead to a more favorable distribution of pressure over the wing's surface, resulting in a notable forward shift in the center of pressure.

In contrast, during high-speed flight, the aerodynamic loads often cause the center of pressure to move aft. Similarly, stall conditions lead to turbulent flow over the wing, significantly altering pressure distributions, which may push the center of pressure back due to the loss of lift associated with a stall. In a constant climb, while the angle of attack can vary, the general tendency does not favor a significant forward movement of the center of pressure compared to low-speed conditions. Thus, low-speed flight is the most accurate scenario for the forward movement of the center of pressure.
