ICAO Annex 14
Simple approach lighting system

5.3.4.2 A simple approach lighting system shall consist of a row of lights on the extended centre line of the runway extending, whenever possible, over a distance of not less than 420 m from the threshold with a row of lights forming a crossbar 18 m or 30 m in length at a distance of 300 m from the threshold.

Barrette. Three or more aeronautical ground lights closely spaced in a transverse line so that from a distance they appear as a short bar of light.

From the aerodrome chart we can see that the airport uses a HIALS (High Intensity Approach Lighting System) for both runways and HIRL (High Intensity Runway Lights). The Approach Lighting System of Runway 03 extends up to 420 m. According to ICAO Annex 14 this is the length required for a simple approach lighting system. (CAT I approach lighting system usually extends up to 900 m.)

On the aerodrome graph the approach lighting system of Runway 03 shows single source lights on the extended centre line and one crossbar, which is the configuration of a simple approach lighting system.

Note1: On the graph the 'dot' lights (.) refer to single source of light and the 'dash' lights (_) refer to a barrette.

Note2: The answer will be different for Runway 21.
