The maximum azimuth coverage by a MLS facility is

  • +/- 35 degrees
  • +/-40 degrees
  • +/-60 degrees

Explanation from PART66Online

An MLS azimuth station provides guidance over a wide sector, with maximum proportional azimuth coverage extending to about plus or minus 60 degrees either side of the runway centreline. This wide coverage is one of MLS's advantages over ILS, allowing curved and segmented approaches within the sector.

Up to +/-60 degrees but usually it is +/-40 degrees. This is an advantage of MLS over ILS.
