SP-401 Solar Approach Light is ICAO compliant solar LED elevated simple approach light designed for permanent usage at Non-Precision Runways located in regions without access to electricity and high photovoltaic potential.
ICAO, Annex 14th, Volume I, 7th Edition dated July 2016, clause 5.3.9.9 & Appendix 1, Figure A1-1b
Runway approach is a part of an airfield located before the beginning of a runway. This is the area where aircraft still cannot land but flies very close to the ground and approaches runway. Runway approach is an open area with no trees, high electrical cables or any other high objects that can interfere aircraft landing. This area, however, is not covered with an asphalt surface.
Approach Lighting System (or ALS) gives a visual indication of runway approach and helps pilots to do landing safely. Approach lighting consists of set of different types of lights. Construction of approahc lighting system is also different depending on the size of airport and types of aircrafts this airport can take flights from.
There are few types of ALS systems recognized by ICAO (International Civil Aviation Organization). However, today airfield lighting suppliers offer much more variations of approach lighting systems. Most of them are high-intensity ALS.
Let’s have a look at the most common ALS systems:
If an airport is located in region with limited access to electrical infrastructure and high photovoltaic potential, solar powered approach lights will be the best solution. S4GA solar approach lights are ICAO compliant airfield lights applicable for permanent usage at airfields. Solar approach lights can be used for short approach lighting systems – SALS, simplified short approach lighting systems (SSALS), omnidirectional approach lighting systems (ODALS) and few other types of ALS.
