Explanatory Note

This Order defines obstacles to aircraft in flight for the purpose of airspace protection in the State at, adjacent to and in the vicinity of aerodromes and elsewhere and specifies reporting and information requirements with respect thereto.

3. Applicability

This Order shall apply to existing and proposed manmade objects of permanent or temporary construction or alteration and apparatus of a permanent or temporary nature or any alteration thereto, objects of natural growth and terrain. The standards shall apply to the use of navigable airspace by aircraft and to existing or proposed air navigation facilities, licensed aerodromes, air traffic services routes including approach and departure routes to and from instrument and other runways.

4. Definition of an Obstacle

(1) An existing object, including a mobile object, is and a future object would be, an obstacle to air navigation if it is of greater height than any of the following heights or surfaces:-

(a) A height of 45 metres above ground level at the site of the object or an object which otherwise constitutes an en-route obstacle or a potential en-route obstacle in accordance with this Order;

(b) A height within a runway approach area, a runway departure area or a circling approach area, which would result in the vertical distance between any point on the object and the established minimum instrument flight altitude or height as specified for the aerodrome concerned in the “AIP Ireland” within that area to be less than the required obstacle clearance. The analysis of the significance of such obstacles may have to be determined by an aeronautical study in accordance with subparagraph (4) of Article 5 of this Order;

(c) The surface of an obstacle limitation surface as defined in Chapter 4 of Annex 14 to the Convention;

(d) The surface of an obstacle protection surface as defined in Chapter 5 of Annex 14 to the Convention;

(e) An inclined plane surface, with a slope of either 1.2 per cent or 1.0 per cent superimposed on a take-off flight path area and extending either to 10 kilometres or 12 kilometres respectively from the end of the runway concerned as specified in Chapter 3 of Annex 4.

(2) The surfaces specified in paragraph (1) above may also be defined in relation to a specific aerodrome on a safeguarding map prepared by or on behalf of the aerodrome licensee and lodged with the local Authority responsible for planning in the vicinity of that aerodrome under the

Planning and Development Act 2000

.

(3) The dimensions, orientation and characteristics of these surfaces are defined in Annexes 4 and 14 to the Convention as appropriate in relation to runway size and use at the aerodrome concerned.

5. Reporting and Information in respect of Obstacles

(1) A person who proposes to erect or to construct an object as defined in paragraph (1)(a) of Article 4 of this Order shall first notify the Authority in writing of that intention and shall provide such information as may be requested under paragraph (3) of this Article, apart from any permission required to be obtained under the

Planning and Development Act 2000

in respect of the said proposal.

(2) A person who proposes to erect or construct an object as defined in Article 4 of this Order within a radius of 10 kilometres of a licensed aerodrome shall first notify the aerodrome licensee in writing of that intention and shall, where requested provide such information to the Authority as may be required under paragraph (3 of this Article, apart from any permission required to be obtained under the

Planning and Development Act 2000

in respect of the said proposal.

(3) The Authority may require the making available to it of information relating to an obstacle, including its geographic latitude and longitude, elevation and height.

(4) The Authority may require the conduct of an aeronautical study for the purposes of paragraph (1)(b) of Article 4 of this Order or otherwise if it considers it necessary in a particular case.

6. Marking and Lighting of Obstacles

The Authority may require the marking and lighting of an obstacle defined in accordance with Article 4 of this Order in accordance with such instructions as the Authority may give in a particular case or by a direction under this Order.

7. Directions

The Authority may give directions in relation to such matters to which the Order relates. Directions under this Order may be issued as Notices to Aerodrome Licensees Aeronautical Information Circulars, by public notice or by private notice in writing sent by post or by electronic means to the organisation, person or persons affected.

8. Guidance Material

The Authority may from time to time publish or otherwise provide guidance documentation on the determination and classification of obstacles for the purposes of this Order.

Given under the common seal of the Irish Aviation Authority this 25th day of January, 2002.
