In aerodynamics, drag is influenced by the flow patterns around an aircraft. In the context of flight conditions, turbulent flow is a significant contributor to increased drag. Slow speed turns typically result in higher drag due to a couple of factors.

When an aircraft is in a slow speed turn, it operates at lower airspeeds where the angle of attack is increased to maintain lift. This increase can lead to flow separation around the wings and other surfaces, resulting in a turbulent wake and increased form drag. The aircraft's relatively slower movement through the air exacerbates these effects, as the airflow struggles to remain attached to the wing surface due to the higher angle of attack.

Additionally, during a slow-speed maneuver, the control surfaces may also need to generate more deflection to maintain the desired flight path, further disrupting the smooth airflow around the aircraft and contributing to increased drag. This turbulence can significantly affect the aircraft's performance, leading to higher overall drag compared to other flight conditions.

In contrast, flight conditions such as high-altitude descents and high-speed straight-and-level flight typically maintain smoother airflow, minimizing turbulence and therefore reducing drag. Low altitude climbs engage different aerodynamic behaviors but may not consistently result in the same turbulent flow as seen in slow speed turns.
