What is the effect of increased AOA during maximum endurance airspeed flight?

During maximum endurance flight, as the angle of attack (AOA) increases, the aircraft approaches aerodynamic stall conditions. This increase in AOA generally requires more power because the aircraft becomes less efficient at generating lift relative to drag. The higher AOA increases induced drag as the lift vector tilts more rearward, which means the engines must work harder to maintain flight. Consequently, this increase in power demand results in a decrease in airspeed, as the plane cannot maintain its optimal performance and begins to lose speed due to the increased drag at a higher angle of attack. This dynamic illustrates the delicate balance of lift, drag, and power requirements during flight, particularly at maximum endurance speeds where efficiency and stability are critical.
