What type of approach lighting system is indicated by symbol A2?

The symbol A2 refers to the Short Approach Lighting System, commonly recognized as SALS or SALSF. This type of lighting system is designed to aid pilots during the approach phase of landing, specifically for approaches that typically occur in lower visibility conditions. The configuration allows for a clearer visual reference to the runway, thereby enhancing safety and precision during landing.

The Short Approach Lighting System features a setup that includes shorter light bars or fixtures spaced at certain intervals leading up to the runway. This design contrasts with longer, more complex systems, which are not necessary for every runway, especially those serving less critical operations. Pilots receive crucial visual cues from these lights that help align the aircraft correctly before touchdown, making it easier for them to maintain their approach path.

Understanding the differences among various approach lighting systems is key for instrument-rated pilots, as it allows them to interpret approach charts properly and prepare adequately for their landing procedures based on conditions and available equipment.
