Given a constant load factor, which of these statements about the variation of induced drag are correct or incorrect?

• A. 1 is correct, 2 is incorrect
• B. 1 is incorrect, 2 is correct
• C. 1 is incorrect, 2 is incorrect
• D. 1 is correct, 2 is correct

Answer: (B)

In assessing the variation of induced drag concerning a constant load factor, it's essential to understand how lift production influences induced drag. Induced drag is a byproduct of generating lift, and it increases with the square of the lift coefficient. When a constant load factor is maintained during flight maneuvers, the aircraft's weight remains unchanged, and the lift generated must equal the weight to maintain level flight. As you increase the angle of attack to generate more lift, you also increase the induced drag. This relationship demonstrates that induced drag will rise as lift coefficients increase for a given constant load factor, especially in conditions of low airspeed or high angles of attack. The statement that has been deemed correct likely articulates a principle that aligns with this understanding—that induced drag varies directly with lift. Conversely, the statement deemed incorrect possibly mischaracterizes the relationship between load factor, lift, and induced drag or presents a misleading concept about how induced drag behaves under varying conditions of flight. This reasoning aligns with the principles of aerodynamics, thereby justifying the choice that indicates the first statement as incorrect and the second as correct under the defined parameters.
