A Correct answer
Explanation

ILS (Instrument Landing System) provides precision approach guidance during landing. It's most essential when visibility is low, as it allows pilots to approach the runway safely even when they can't see it clearly. The system provides both lateral (left/right) and vertical (up/down) guidance through radio signals.
