Answer: Best Climb Angle Indicated Velocity (Vx) determination is not affected by headwind but the climb angle will be greater
Step-by-step explanation:
The best climbing angle is the angle of climbing for which the airplane can attain maximum height in a specified distance. On increasing the headwind, the climbing angle increases and it does not affect the climb angel velocity (Vx).
therefore Best Climb Angle Indicated Velocity (Vx) determination is not affected by headwind but the climb angle will be greater
