How does the load factor change when flying above L/D(MAX)?

When flying above the lift-to-drag ratio maximum (L/D(MAX)), the load factor increases. This increase occurs because as an aircraft operates in this region, it begins to require a greater angle of attack to maintain level flight or produce the necessary lift. At this higher angle of attack, induced drag becomes more significant, necessitating an increase in thrust to overcome this drag while keeping the aircraft aloft.

As a result, the plane must generate more lift to counteract its weight, which leads to an increase in load factor. The load factor is a measure of the load supported by the wings relative to the aircraft’s weight. In scenarios where the lift required surpasses what can be efficiently provided due to the aerodynamic inefficiencies encountered at these angles, the aircraft experiences higher load factors. This phenomena highlights the importance of understanding the operational limits of an aircraft and the effects of aerodynamic principles on performance in various flight regimes.
