||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
THIRD SCHEDULE |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Rules for the interception of aircraft |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
1. General |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Interception should be limited to determining the identity of the aircraft, unless it is necessary to return the aircraft to its proper track, direct it beyond the boundaries of Irish airspace, guide it away from a prohibited area, a restricted area or a danger area or instruct it to effect a landing at an aerodrome designated in the instruction. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
2. Manoeuvres for visual identification of a civil aircraft |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Phase I |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
The intercepting aircraft should approach the intercepted aircraft from astern. The element leader or the single intercepting aircraft should normally take up a position on the left (port) side, slightly above and ahead of the intercepted aircraft, and initially not closer to it than 300 metres. Any other participating aircraft should stay well clear of the intercepted aircraft, preferably above and behind. After speed and position have been established, the element leader or the single intercepting aircraft should, if necessary, proceed with Phase II of the procedure. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Phase II |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
The element leader or the single intercepting aircraft should begin closing in gently on the intercepted aircraft, at the same level, until no closer than absolutely necessary to obtain the information needed. The element leader or the single intercepting aircraft should use caution to avoid startling the flight crew or the passengers of the intercepted aircraft, keeping constantly in mind the fact that manoeuvres considered normal to an intercepting aircraft may be considered hazardous to passengers and crews of civil aircraft. Any other participating aircraft should continue to stay well clear of the intercepted aircraft. Upon completion of identification, the element leader or the single intercepting aircraft should withdraw from the vicinity of the intercepted aircraft as outlined in Phase III. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Phase III |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
The element leader or the single intercepting aircraft should break gently away from the intercepted aircraft in a shallow dive. Any other participating aircraft should stay well clear of the intercepted aircraft and rejoin their leader. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
3. Manoeuvres for navigational guidance of an intercepted aircraft |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
(1) If, following the identification manoeuvres in Phase I and Phase II of paragraph 2 of this Schedule, it is considered necessary to intervene in the navigation of the intercepted aircraft, the element leader or the single intercepting aircraft should normally take up a position on the left (port) side, slightly above and ahead of the intercepted aircraft, to enable the pilot-in-command of the latter aircraft to see the visual signals given. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
(2) The pilot-in-command of the element leader or the single intercepting aircraft should satisfy himself that the pilot-in-command of the intercepted aircraft is aware of the interception and acknowledges the signals given. If repeated attempts to attract the attention of the pilot-in-command of the intercepted aircraft by use of the signal specified at series number 1 in the First Schedule to this Order are unsuccessful, other methods of signalling may be used for this purpose, including as a last resort the visual effect of the reheat/afterburner: |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Provided that no hazard is thereby created for the intercepted aircraft. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
(3) Where meteorological conditions or terrain make it necessary for the element leader or the single intercepting aircraft to take up a position on the right (starboard) side slightly above and ahead of the intercepted aircraft, the pilot-in-command of the intercepting aircraft shall take particular care to ensure that his aircraft is clearly visible at all times to the pilot-in-command of the intercepted aircraft. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
4. Guidance of an intercepted aircraft |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
(1) Navigational guidance and related information shall be given to an intercepted aircraft by radiotelephony, whenever radio contact can be established. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
(2) When navigational guidance is given to an intercepted aircraft, the element leader or the single intercepting aircraft shall ensure that the other aircraft is not led into conditions where the visibility may be reduced below that required to maintain flight in visual meteorological conditions and the manoeuvres demanded of the intercepted aircraft do not add to already existing hazards in a case where the operating efficiency of the intercepted aircraft is impaired. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
(3) In the exceptional case where an intercepted aircraft is required to land in the territory overflown, the element leader or the single intercepting aircraft shall ensure that-- |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
( a ) the designated aerodrome is suitable for the safe landing of the aircraft type concerned, especially if the aerodrome is not normally used for civil air transport operations, |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
( b ) the surrounding terrain is suitable for circling, approach and missed approach manoeuvres, |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
( c ) the intercepted aircraft has sufficient fuel remaining to reach the aerodrome, |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
( d ) if the intercepted aircraft is a civil transport aircraft, the designated aerodrome has a runway with a length equivalent to at least 2,500 metres at mean sea level and a bearing strength sufficient to support the aircraft, and |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
( e ) whenever possible, the designated aerodrome is one that is described in detail in the relevant aeronautical information publication. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
(4) When requiring an aircraft to land at an unfamiliar aerodrome the element leader or the single intercepting aircraft shall allow it sufficient time to prepare for a landing, bearing in mind that only the pilot-in-command of the intercepted aircraft can judge the safety of the landing operation in relation to runway length and aircraft mass at the time. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
GIVEN under my Official Seal this 12th day of January, 1990. |

SÉAMUS BRENNAN, |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Minister for Tourism and Transport. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
EXPLANATORY NOTE. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
This Order, made by the Minister for Tourism and Transport, makes detailed provision for the interception (including the required landing) of civil aircraft flying without authority or being used for any purpose inconsistent with the 1944 Chicago Convention on International Civil Aviation, as required by the 1984 Protocol to that Convention. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Contravention of the Order in relation to any aircraft could entail prosecution for an offence. Such an offence would be punishable by the following penalties-- |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
on summary conviction: a fine not exceeding £1,000 and/or imprisonment for a term not exceeding 6 months, or |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
on conviction on indictment: a fine not exceeding £50,000 and/or imprisonment for a term not exceeding 3 years ( section 13 of the Air Navigation and Transport Act, 1946 (No. 23) as amended by section 28 of the Air Navigation and Transport Act, 1988 (No. 15) refers). |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
The principal element of the 1984 Protocol is its obligation on each State party thereto to refrain from the use of weapons against civil aircraft in flight and to safeguard the lives of persons on board and the safety of other aircraft and persons on board, but without prejudice to the right of each such State to act in self-defence as set forth in the Charter of the United Nations. That obligation is enshrined in section 38 of the Air Navigation and Transport Act, 1988 (which amended provisions of the Air Navigation and Transport Act, 1946 , relating to the Chicago Convention). |
