VASI stands for which lighting system?

Explanation:
Visual Approach Slope Indicator lights provide the pilot with a visual glide-path cue on final approach. The name itself matches what VASI stands for: Visual Approach Slope Indicator lights. This system is mounted beside the runway and uses a color pattern to indicate whether you’re on the correct descent angle, helping you stay on the intended glide slope even when relying on visual cues. The other phrases listed aren’t established aviation terms for this lighting setup, so they don’t describe a real system used in approach lighting.
