Which acronym denotes the height of the DA/MDA above a designated helicopter landing area elevation?

HAL, or Height Above Landing, denotes how high the DA/MDA is above the elevation of the designated helicopter landing area. This surface-based reference is essential because the landing spot on a helicopter operation can vary in elevation, so using HAL keeps the calculated decision height directly tied to the actual surface you’re aiming to land on. In contrast, terms like height above touchdown or other surface references describe different references that aren’t specific to the helicopter landing area. By expressing DA/MDA as HAL, pilots know the exact clearance above the landing area, supporting safer descent and landing decisions.
