Department of Airports in Thailand, a government department under the Ministry of Transport, entrusted S4GA with a project of upgrading the PAPI System at one of Thai regional airports. The installation took place at Mae Hong Son Airport. DoA was looking for both reliable and easy to maintain PAPI System powered by 6.6 Amp electrical grid.
Mae Hong Son is a civil airport servicing small province in the north-western part of Thailand. The airport is equipped with permanent runway lighting and halogen precision approach path indicators. However, the PAPI system required a complete modification. DoA Management made a decision to invest in a new LED PAPI. The main challenge for the Customer was to find a solution being in the same time reliable, cost-effective, and requiring a simple maintenance.
Simplicity of design was an important factor for the Customer to choose S4GA. Another required aspect was an ability to have maintenance performed by local technical staff only familiar with halogen PAPI before.
All things considered , S4GA LED Precision Approach Path Indicators powered by 6.6 Amp electrical grid were found the best solution addressing all Customer’s requirements:
S4GA LED PAPI Lights are equipped with TILT sensors as one of the requirements provided by DoA. Airport personnel can also monitor the PAPI “health”: the lights send feedback information to Tower using a communication cable.
S4GA LED PAPI as well as other airfield lighting products are fully compliant with ICAO, FAA, EASA, CASA requirements and certified by accredited laboratories. Moreover, S4GA LED PAPI Lights have the most illumination compared to competitor products. This feature allows for an extra safety margin for airports located in areas where adverse weather conditions may appear and disturb operations.
