What does the Instrument Landing System provide?

• A. Weather information
• B. Altitude restrictions
• C. Lateral and vertical guidance
• D. Terrain avoidance data

Answer: (C)

The Instrument Landing System provides precise guidance for an approach by delivering both horizontal and vertical guidance to the runway. The localizer gives lateral guidance, keeping the aircraft centered on the runway centerline, while the glideslope provides vertical guidance, guiding descent along a fixed glide path to the runway. Together, they let a pilot fly a precision approach with accurate alignment and descent. Weather information, altitude restrictions, and terrain avoidance data come from other systems or sources, not the ILS itself.
