The 0‑­line is marked by a white line, 0.01m wide which extends beyond the outside edges of the uprights.The two uprights must be installed on horizontal bases, level with the 0‑­line, such that each can be moved from the 0‑­line not less than 0.80m towards the landing area (eg on a built‑­in double rail) or in fixed sockets with movable cross bar supports.

In the case of a runway with a permanent surface, this requires a built‑­in installation tray made of corrosion protected metal in which the take‑­off board is correctly positioned.
