MLS refers to what system?

• A. Missile Landing System
• B. Microwave Landing System
• C. Magnetic Lateral System
• D. Multi-Light System

Answer: (B)

MLS is Microwave Landing System, a precision approach and landing system that uses microwave signals to provide accurate guidance to the aircraft during the final approach. It delivers lateral guidance (azimuth) and vertical guidance (elevation) through ground-based transmitters and a compatible cockpit or airborne receiver, allowing the pilot to follow a defined path to a stabilized descent and landing. The system’s signals are scanned and decoded by the aircraft to present the flight path, which can offer very precise approach guidance and flexibility in path design compared to some older systems.

The other options don’t correspond to an established aviation landing system. A missile-related landing system isn’t used in civil aviation, magnetic lateral system isn’t a standard term for approach guidance, and a multi-light system isn’t a recognized precision approach method.
