SECTION 82.0
Issue 3
3B Conditions for route distance limitations

3B CONDITIONS FOR ROUTE DISTANCE LIMITATIONS

Interpretation

3B.1 For the purposes of this subsection, type means a particular airframe/engine combination.

Extended range operations in three or four engine aeroplanes

3B.2 Each certificate authorising charter or regular public transport operations in a three or four engine aeroplane to which section 20.7.1B applies, carrying passengers for hire or reward, is subject to the condition set out in paragraph 3B.3.

3B.3 The aeroplane must not be operated more than 90 minutes flight time, calculated at normal cruising speed, away from an adequate aerodrome unless compliance with the flight path obstacle clearance rules of paragraphs 12.5, 12.6 and 12.7 of section 20.7.1B can be shown, assuming two engines failed at
the most critical point along the route that is in excess of 90 minutes flight time at normal cruising speed from an adequate aerodrome.

Extended range operations in twin-engined aeroplanes certificated for 19 or fewer passengers

3B.4 Each certificate authorising passenger carrying regular public transport operations in a twin-engined aeroplane:
(a) to which section 20.7.1B applies; and
(b) that is of a type certificated for 19 or fewer passengers;

is subject to the condition that the aeroplane must not be operated on extended range operations when carrying passengers unless the operator has obtained the specific approval, in writing, of CASA.

3B.5 When approving the operation of an aeroplane referred to in paragraph 3B.4 on extended range operations, CASA may impose any conditions that it considers necessary.

3B.6 In deciding:
(a) whether or not to issue an approval under paragraph 3B.4; and
(b) what conditions, if any, it should impose on that approval;

CASA will consider the following factors:
(c) the operator’s experience and ability;
(d) the type of aeroplane to be flown;
(e) the route to be flown.

Extended range operations in twin-engined aeroplanes certificated for more than 19 passengers

3B.7 Subject to paragraph 3B.8, each certificate authorising passenger carrying charter or regular transport operations in a twin-engined aeroplane that is of a type certificated for more than 19 passengers is subject to the condition that the aeroplane must not be operated on an extended range operation, when carrying passengers, without the written approval of CASA for that specific operation.

3B.8 Paragraph 3B.7 does not apply to an aircraft of a type first registered in Australia on or before 28 October 1985 and operated by the same operator as on 30 November 1989, that is to be operated on a route where the flight time to an adequate aerodrome does not exceed:
(a) 90 minutes at normal cruise speed when all operations are within the Australian Flight Information Regions;
(b) 90 minutes at normal cruise speed on routes outside the Australian Flight Information Regions that were approved for the aeroplane type before 28 October 1985; and
(c) 60 minutes at single engine cruise speed in all other cases.

Note: CASA may approve operations on routes outside the Australian Flight Information Regions that were not approved before 28 October 1985 provided that a history of safe
operations on a similar route can be demonstrated.

Approval of specific extended range operation to follow airworthiness assessment and safety operational specification

3B.9 For the purposes of paragraph 3B.7, CASA may approve, in writing, specific extended range operations for a twin-engined aeroplane provided that:
(a) the operator has given CASA the documents that the operator is required to provide under Appendix 3 to enable an airworthiness assessment to be carried out; and
(b) following the conduct of an airworthiness assessment in accordance with Appendix 3, CASA is satisfied that the operator is able safely to conduct and maintain those operations; and
(c) the maximum operating time in still air to an adequate aerodrome is included in a safety operational specification made under the authority of subsection 4; and
(d) the maximum specified operating time does not exceed that for which airworthiness approval has been granted under Appendix 3; and
(e) any conditions prescribed in the safety operational specification referred to in subparagraph (c) are complied with.

Cruise speed must be specified in operations manual

3B.10 Each certificate authorising charter or regular public transport operations is subject to the condition that the normal cruise speed (for all aeroplanes) and the one engine inoperative cruise speed (for twin-engined aeroplanes) used in compliance with this subsection must be specified in the operations manual.
