HAT stands for height above touchdown. Which acronym denotes this parameter?

In aviation, height above touchdown is the vertical distance from the aircraft to the runway’s touchdown point. The label is formed by taking the initial letters of the three words: Height Above Touchdown. That makes HAT the exact shorthand used to denote this specific measurement in charts and approach procedures. It’s distinct from height above airport elevation or other heights used in flight planning, because it zeroes in on how high the aircraft is right at the point where it would touch down. The other acronyms don’t correspond to this exact phrase, so they wouldn’t be the standard way to label this parameter.
