What happens to the lift vector during a high-speed turn?

During a high-speed turn, the dynamics of lift are significantly affected by the relationship between airspeed and the aircraft's ability to generate lift. As an aircraft increases its speed during a turn, the increased centrifugal force comes into play. This force opposes the lift vector, causing the effective lift to become directed more horizontally rather than vertically.

In this scenario, the required lift for maintaining altitude must balance not only the weight of the aircraft but also provide the necessary force to counteract the centrifugal effect experienced during the turn. As a result of these dynamics, while the total lift could momentarily be increased due to higher speeds, the net vertical component becomes less efficient, effectively resulting in a decrease in the lift force that counters the weight of the aircraft, leading to a requirement for increased angle of attack to maintain altitude.

Consequently, during a high-speed turn, the lift vector is effectively compromised as it does not provide the necessary vertical support, leading to a decrease in effective lift when considering the need for both vertical and horizontal balance. Thus, the lift vector decreases during these specific flight conditions.
