Chromaticity measurement of airport navigation lighting using integrated colour sensor

Vol. 31, No. 4

art. no. e147040

The paper presents an analysis of using a TCS3430 light colour sensor to verify the chromaticity of navigation lighting installed at airports. These measurements can help determine the correct operation of the tested lamp using of specialised measuring devices. The emitted light colour is critical for pilots during flight operations such as take-off, landing and taxiing, especially in low visibility conditions. Chromaticity standards (in CIE1931 colour space) are specified in the relevant regulations of the European Union Aviation Safety Agency (EASA) and the International Civil Aviation Organisation (ICAO), and require regular inspection of each light point (both in-pavement and elevated lamps). Tests were carried out for various types of aviation navigation lighting lamps. The stability of measurements and possibilities of visualization on the chromaticity chart were assessed. The article also presents software that allows for quick verification of the operation of a given lamp, intended for airport maintenance services.
