If other than a runway centerline localizer is used, the criteria in subpart C of part 97 of this chapter is applicable. (b) On runways where limited terrain prevents the localizer antennae from being positioned on the runway centerline extended, and the cost of the land fill or a tall tower antenna support is prohibitive, the localizer antenna array may be offset, including a collocated ground station, so that the course intercepts the centerline at a point determined by the amount of the angular offset and the glide path angle. (6) Be installed on frangible mounts or beyond the 1000′ light bar. (5) Not obscure any light of the approach landing system and (4) Be located at a distance from the stop end of the runway that is consistent with safe obstruction clearance practices (3) Have the minimum height necessary to comply with the coverage requirements prescribed in paragraph (j) of this section (2) Be adjusted so that the course line be on a vertical plane containing the centerline of the runway served (1) Be located on the extension of the centerline of the runway at the stop end
This section prescribes the performance requirements for localizer equipment components of the ISMLS. § 171.261 Localizer performance requirements.
