S.I. 71, 1996.
This Order may be cited as the Civil Aviation, Land Use Control (Sir Seretse Khama Airport) Order.
2. Application of provisions of Order
This Order shall apply to those areas of land and water situated on or near Sir Seretse Khama Airport and covered by the descriptions set out in the First Schedule hereto, which areas may herein be referred to as “controlled areas”.
3. Limitation on height of structures or trees
Except as otherwise provided in this Order, no person shall erect, alter or maintain any structure or grow any tree of a height in excess of the limits set out in respect of each controlled area as indicated in the Second Schedule hereto.
4. Restrictions on use of controlled areas
Notwithstanding any other provisions of this Order, no use may be made of land or water within any controlled area established by this Order in such a manner as to create any electrical interference with navigational signals or radio communication between the airport and aircraft, make it difficult for pilots to distinguish between airport lights and other illuminations, result in glare in the eyes of pilots using the airport, impair visibility in the vicinity of the airport, create bird strike hazards, or otherwise in any way endanger or interfere with the landing, takeoff, or manoeuvering of aircraft intending to use the airport.
5. Exemption of existing structures and trees
This Order shall not be construed so as to require the removal, lowering, or other change or alteration of any structure not conforming to the requirements of this Order as at the effective date thereof, or otherwise interfere with the continuance of the normal use thereof, and nothing contained herein shall require any change in the construction, alteration or intended use of any structure, the construction or alteration of which was begun prior to the date of commencement of this Order, and is continued without delay in accordance with the original plans.
6. Marking and lighting of obstructions
Notwithstanding the provisions of paragraph 5, the owner of any existing structure or tree which does not conform with the requirements of this Order shall permit the installation, operation, and maintenance thereon, at the expense of the Department of Civil Aviation, of such markers and lights as are deemed necessary by the Department of Civil Aviation to indicate the presence of any such obstruction to the operators of aircraft in the vicinity of the airport.
7. Limitation on changes in use of controlled areas
(1) No material change shall be made in the use of land, and no structure shall be erected or otherwise established in any controlled area unless a permit therefor has been granted by the Director of Civil Aviation.
(2) Every application for a permit shall be made in writing to the Director of Civil Aviation, shall specify the purpose for which the permit is required, and contain sufficient particulars to enable the Director to determine whether the structure, or the resulting use, would conform to the requirements of this Order.
(3) No permit shall be granted for a structure or a use which does not conform with the requirements of this Order, and no permit shall be granted that would allow the establishment or creation of an obstruction, or permit a structure or tree or the use thereof or of land to become a greater hazard to air navigation than it was on the date of commencement of this Order.
8. Abandoned or destroyed obstruction not to be restored
Whenever in the opinion of the Department of Civil Aviation a tree or structure which does not conform with the requirements of this Order has been abandoned or more than 80 per cent torn down, has physically deteriorated, or decayed, no permit shall be granted that would allow such structure or tree to be restored so as to exceed the applicable height limit or otherwise deviate from the requirements of this Order.
9. Owner may be required to mark and light obstruction
Any permit granted under this Order may, if the Director of Civil Aviation considers it to be advisable for the purposes of this Order and to be not unreasonable in all the circumstances, be granted subject to the condition that the owner of the structure or tree in question install, operate, and maintain, at his own expense, such markings and lights as may be necessary in the interest of safety.
Any person who contravenes or fails to comply with any provision of this Order with which he is required to comply, shall be guilty of an offence and shall be liable to a fine of P500 and to imprisonment for 6 months.
FIRST SCHEDULE
1. Approach Surfaces
Description – An approach surface is an inclined plane or combination of planes preceding the thresholds of:
(a) the existing 3 000 metre runway, of orientation 08-26; or
(b) the future 4 000 metre runway, to be developed by extending 1 000 metres at 26 end (eastern end) of the existing runway.
Characteristics – The limits of the approach surface shall comprise:
(a) an inner edge of 300 metres in dimension, perpendicular to the extended centre line of the runway and located at 60 metres distance before the threshold;
(b) two sides originating at the ends of the inner edge and diverging uniformly at a rate of 15 per cent from the extended centre line of the runway; and
(c) an outer edge parallel to and 15 000 metres distant from the inner edge.
The elevation of the inner edge shall be equal to the elevation of the mid-point of the threshold.
The slope(s) of the approach surface shall be measured in the vertical plane containing the centre line of the runway.
The approach surface consists of three contiguous sections as indicated below:
First section: Inner edge to 3 000 metres at a two percent slope;
Elevation at 3 000 metres is 60 metres above the inner edge.
Second section: 3 000 metres from the inner edge to 6 600 metres from the inner edge at a 2,5 per cent slope;
Elevation at 3 000 metres is 60 metres, and at 6 600 metres is 150 metres above the inner edge.
Third section: A horizontal surface of elevation 150 metres above the inner edge commencing at 6 600 metres from the inner edge and ending at 15 000 metres from the inner edge.
2. Take-off climb surface
Description – Take-off climb surface is an inclined plane beyond the end of clearways of:
(a) the existing 3 000 metre runway of orientation 08-26; or
(b) the future 4 000 metre runway to be developed by extending 1 000 metres at the 26 end (eastern end) of the existing runway.
Characteristics – The limits of the take-off climb surface shall comprise:
(a) an inner edge of 180 metres in dimension horizontal and perpendicular to the centre line of the runway and located at the end of the clearway;
(b) two sides originating at the ends of the inner edge diverging uniformly at a rate of 12,5 per cent from the take-off track to a 1 800 metre final width and continuing thereafter at that width for the remainder of the length of the takeoff climb surface; and
(c) an outer edge horizontal and perpendicular to the specified take-off track; parallel to and 1 500 metres distant from the inner edge.
The elevation of the inner edge shall be equal to the highest point on the extended runway centre line between the end of the runway and the inner edge, i.e. the highest point of the ground on the centre line of the clearway.
The slope of the take-off climb surface shall be measured in the vertical plane containing the centre line of the runway, and shall have a value of 1.6 per cent commencing from the inner edge. The elevation of the outer edge is 240 metres above the inner edge.
3. Transitional Surface
An area bounded by:
(a) two parallel lines 930 metres apart and symmetrically placed 465 metres on either sides of the centre of the runway; and
(b) the approach surfaces on either ends of the existing and the future runways.
4. Inner Horizontal Surface
An area within 4 kilometres from any point on the existing and future runways.
