Which statement correctly defines HAL?

Explanation:
HAL is the vertical distance from the aircraft to the landing surface. Think of it as how high you are above the surface you are aiming to land on—the runway in normal operations. This measure changes as you descend: it decreases on the approach and becomes zero at touchdown. It’s different from altitude above sea level or above the airport as a whole, and it’s tied specifically to the surface you’ll land on, not a fixed geographic reference. That’s why the statement defined as Height Above Landing best captures what HAL means.
