Definition
Touchdown Zone lights define the touchdown zone of a runway, and are installed on some precision approach runways to facilitate landing and Take-off under adverse visibility conditions.
Description
Touchdown zone lights shall extend from the threshold for a longitudinal distance of 900 metres, except that on runways less than 1800 metres in length, the system shall be shortened so that it does not extend beyond the midpoint of the runway. The pattern shall be formed by pairs of barrettes symmetrically located about the runway centre line. The lateral spacing between the innermost lights of a pair of barrettes shall be equal to the lateral spacing selected for the touchdown zone marking. The longitudinal spacing between pairs of barrettes shall be either 30 metres or 60 metres.
