When the weight of an aircraft increases, the minimum drag speed
- decreases.
- increases.
- is unaffected.
Explanation from PART66Online
Minimum drag occurs where induced drag equals profile drag, and a heavier aircraft must generate more lift, raising the induced drag at any given speed. To restore the balance point the aircraft must fly faster, so the minimum drag speed increases with weight, scaling roughly with the square root of weight.
