   (b)  Any  construction or alteration that exceeds an imaginary surface
   extending outward and upward at any of the following slopes:

   (1) 100 to 1 for a horizontal distance of 6.10 kilometers (20,000 feet) from
   the  nearest  point of the nearest runway of each airport described in
   paragraph  (d)  of this section with its longest runway more than 0.98
   kilometers (3,200 feet) in actual length, excluding heliports.

   (2) 50 to 1 for a horizontal distance of 3.05 kilometers (10,000 feet) from
   the  nearest  point of the nearest runway of each airport described in
   paragraph (d) of this section with its longest runway no more than 0.98
   kilometers (3,200 feet) in actual length, excluding heliports.

   (3) 25 to 1 for a horizontal distance of 1.52 kilometers (5,000 feet) from

   (c) When requested by the FAA, any construction or alteration that would be
   in an instrument approach area (defined in the FAA standards governing
   instrument approach procedures) and available information indicates it might
   exceed an obstruction standard of the FAA.

   (d) Any construction or alteration on any of the following airports and

   construction or alteration:

   (1) Any object that will be shielded by existing structures of a permanent
   and substantial nature or by natural terrain or topographic features of
   equal or greater height, and will be located in the congested area of a
   city, town, or settlement where the shielded structure will not adversely
   affect safety in air navigation;

   (2) Any air navigation facility, airport visual approach or landing aid,
   aircraft arresting device, or meteorological device meeting FAA-approved
   siting  criteria or an appropriate military service siting criteria on
   military  airports,  the location and height of which are fixed by its
   functional purpose;

   (3) Any antenna structure of 6.10 meters (20 feet) or less in height, except
   one that would increase the height of another antenna structure.

   Note to § 17.7: Consideration to aeronautical facilities not in existence at
   the time of the filing of the application for radio facilities will be given
   only when proposed airport construction or improvement plans are on file
   with  the Federal Aviation Administration as of the filing date of the
   application for such radio facilities.
