ZA484 Inset Runway Centreline / TDZ Light

The ZA484 is ATG Airports' inset runway centreline and touchdown zone (TDZ) fitting from their ZA-series product range — an established fixture designed to satisfy a particularly broad regulatory matrix that spans civil aviation authorities across multiple continents. Its approvals include FAA AC 150/5345-46D (L-850A, B, C, D and Class I/IIB), ICAO Annex 14, NATO STANAG 3316, CAA CAP 168, Transport Canada, Australian MOS 139, and EASA NPA2010-20 — a coverage that makes it a practical choice for international airport operators or contractors procuring for multi-jurisdiction programmes.

As a dual-purpose centreline and TDZ fitting, the ZA484 covers both the white centreline guidance role along the full runway length and the unidirectional white TDZ illumination function in the first 900 metres beyond the threshold. A single qualified product covers both circuit types, simplifying spares holding and training requirements for airport engineering teams.

The fitting is rated for Category I, II, and III all-weather operation — the complete civil precision approach envelope. Its inset design suits the standard seating-pot installation pattern used across the runway system, and it operates on the 6.6 A series circuit standard common to ATG's full product portfolio.

For GCC airports with international operator bases, military tenants, or regulatory oversight from more than one civil aviation authority — a common situation at UAE and Saudi airports with both GCAA/GACA and ICAO obligations — the ZA484's multi-standard approval profile reduces qualification risk on new runway lighting programmes.
