What does the acronym MLS stand for in the context of aircraft approaches?

In the context of aircraft approaches, the acronym MLS stands for Microwave Landing System. This system is designed to provide precise guidance for aircraft during the final approach and landing phases, using microwave frequencies to deliver accurate positional information to pilots and onboard instruments. The MLS offers advantages over traditional landing systems, such as the Instrument Landing System (ILS), by permitting greater flexibility in approach paths and being less susceptible to certain weather conditions.

The MLS utilizes ground-based transmitters to send signals to the aircraft, allowing for improved vertical and horizontal guidance. This advanced technology helps in enhancing safety during landings, especially in challenging conditions where visibility might be low. The use of microwaves allows for higher quality signal reception, contributing to the overall efficiency of the landing process.
