Article 4

The aviation safety of an airport, airfield, and the vicinity that provides aircraft landing or circling range standard is as follows:

1.  Approach runway:

1) Taoyuan Airport, Taipei Airport, and Kaohsiung Airport approach runways in the north runway are the tilted
　 surfaces constructed 60 meters from the runway side. They have a width of 300 meters and are 15,060
     meters from  the runway side, with a width of 4800 meters. The surface extends from inside to outside to
     3060 meters away  from the runway and has a height distance ratio of 1:50; the extended approach
     runways are located between 3060  meters to 15060 meters away from the runway and have a height
     distance ratio of 1:40.

2) Kaohsiung Airport's approach runway of the south runway is the tilted surface constructed 60 meters from
   the runway side. It has a width of 150 meters and is 3060 meters from the runway side, with a width of 750
   meters and has a height distance ratio of 1:40.

3)  Kinmen Airport's approach runway is the tilted surface constructed 60 meters from the runway side. It has
     a width of 300 meters, is 15,060 meters from the runway side, and has a width of 4800 meters. The
     surface extends from inside to outside to 3060 meters away from the runway and the height distance ratio
     is 1:50. The extended approach runway is located between 3060 meters to 6660 meters away from the
     runway, with a height distance ratio of 1:40. The location between 6660 meters and 15060 meters away
     from the runway is a plane surface.

2.  Horizontal surface:

1) Kaohsiung Airport's horizontal surface uses the center point of both sides of the south runway as the
    midpoint. It uses 3000 meters, 5000 meters, 7500 meters and 10000 meters as the radius to make an arc.
    The oval plane surface is constructed by the ranges of each arc and the bisecting line. Each plane's
    surface height from the airport respectively is 60 meters, 90 meters, 120 meters and 150 meters. In
    between each plane surface uses the height distance ratio of 1:20, it extends from outside to the runway
    direction. The north runway does not have any horizontal surface set up.

2) Taoyuan Airport: It uses the center point of both sides of the runway as the midpoint, in the 45 meters
    above the airport, and uses a 4000 meter radius as the arc, the plane surface constructed by the ranges of
     each arc and the bisecting line.

3)  Taipei Airport: It is only set up on the south side of the runway, which uses the center point of both sides of
     the runway as the midpoint, in the 60 meters above the airport, and uses a 3000 meter radius as the arc,
     the plane surface constructed by the ranges of the two arcs and the bisecting line parallel with the runway.

(4) Kinmen Airport: It uses the center point of both sides of the runway as the midpoint, in the 45 meters
     above the airport, and uses a 4000 meter radius as the arc, the plane surface constructed by the ranges of
     each arc and the bisecting line.

3.   Transfer surface:

1) Kaohsiung Airport: The transfer surface is the tilted surface 150 meters north of the north runway central
    line. It extends north for 2100 meters. It has a height 300 meters, and a height distance ratio of 1:7. The
    tilted surface 75 meters south from the south runway central line extends south for 420 meters. The height
    is 60 meters, and the height distance ratio is 1:7.

2) Taoyuan Airport, Kinmen Airport: The transfer surface is the tilted surface 150 meters from the runway central line and extends to the joint of the approach runway; the height distance ratio is 1:7.

3) Taipei Airport: The transfer surface is the tilted surface 150 meters from the runway central line and extends
    for 2100 meters. The height distance ratio is 1:7. However, the horizontal surface in the south side of the
    runway only extends to the joint location of the horizontal surface.

4.Cone surface:

Taoyuan Airport, Kinmen Airport: The cone surface range is the tilted surface constructed in the vicinity of the horizontal surface which goes up 2000 meters. The tilted surface height distance range is 1:20.

The above-mentioned range of the aviation safety standard is a restricted building zone.

Article 5

    antenna  (type 1 ILS) or 90 meters (type 2 and 3 ILS) to the runway side, shall be flat.

2.The rectangle area of ILSGP, starting from the runway central line to the antenna and extending 60 meters
    (type 1 ILS) or 90 meters (type 2 and 3 ILS) wide and starting from the antenna and extending to the
    runway direction for 915 meters (type 1 ILS) or 975 meters (type 2 and3 ILS), shall be flat.

3.Area of the VOR uses the antenna as the center, and the radius within 300 meters shall be flat.

4.All the objects that will cause radio wave reflection 300 meters outside the area of the VOR which uses the

5.ASDE: Use the antenna as the center, any object heights in the areas within a radius of 350 meters shall be
   lower  than the radar antenna platform. There shall be no projections on the approach runway and its above
    area for any  objects that use the radar antenna as the observation point.

6. 30 meters around the navigation aids light facility, all object heights shall not be higher the lower edge of the
    light  source.

    buildings or other objects; the original building shall be removed by the owner notified by the local city and
    county government; the original other objects will be handled by CAA and the related government agencies.

2. In the restricted building zone, in addition to the required facilities for flight safety, the height of the building
    and other objects shall be handled in accordance with article 4 or 6.1.4~6.1.6; the original building's height
    over the flight safety standard, CAA shall request the city and county government to notify the owner to
    remove the parts  that exceed the height or place obstacle lights and signals; other original objects will be
    handled by CAA and the related government agencies.

If the removal or obstacle lights and signal placement for buildings or other objects mentioned earlier already exist when this regulation is promulgated, CAA shall use the local city or county government relevant compensation regulations and give compensation.
