Abstract: This paper describes the design considerations associated with the development of a flare guidance subsystem for the time reference scanning beam (TRSB) microwave landing system (MLS). The two basic concepts for providing MLS flare guidance information are examined; the touchdown zone and wind model are defined; technologies and equipment that are candidates for providing flare guidance are identified; the advantages of the MLS in providing a transition capability from glide slope to altimetry are discussed; various flare algorithms are tabulated, flare antenna option is presented with configuration decision guidelines; and flight test results are shown that demonstrate the guidance capability of the elevation antenna in the approach threshold vicinity.
