Definition
The first 3,000 feet of the runway beginning at the threshold, used for landing performance calculations and as the intended area for an aircraft's wheels to first contact the runway.
Plain English
The part of the runway, starting at the near end, where you are supposed to land. It is the first 3,000 feet past the runway threshold.
Context Anchor
You will see this term in runway marking discussions, landing performance planning, approach briefings, and airport information.
Derivation
Combines 'touchdown,' referring to the moment wheels contact the surface, with 'zone,' meaning a defined segment. This clarifies the term refers to a specific measured portion rather than any random point of contact.
Why Pilots Care
Landing within this zone ensures adequate runway remains for stopping and satisfies performance and regulatory requirements for the approach.
Intuition Check
Do not read touchdown zone as wherever the airplane happens to touch down. In FAA use, it means a specific runway area: the first 3,000 feet starting at the landing threshold.
Example Sentence 1
The instructor reminded the student to aim for the touchdown zone markings rather than the numbers at the very start of the runway.
Example Sentence 2
Touchdown zone markings help the pilot confirm they are landing in the correct part of the runway during low-visibility approaches.
