TDZ stands for which term?

In aviation, this refers to the touchdown zone—the portion of the runway beginning at the threshold where a landing aircraft should make initial contact. The term is used on runway markings and in performance calculations to identify where the landing touchdown should occur. The other phrases aren’t standard aviation terms, so they don’t fit how pilots and airports describe the landing area.
