Touchdown Zone Marking and Aiming Point

The touchdown zone is the first 3,000 feet of the runway or the first third of the runway, whichever is less, measured from the threshold in the direction of landing.

Where an aiming point marking is provided:

  • It is white and located at a specific distance from the threshold per the table below.
  • Takes precedence over touchdown zone markings, therefore, a pair of touchdown zone markings is omitted if it would otherwise fall within 50 metres of the aiming point marking.
