— more than 240 minutes, twin-engine

       (1)This clause applies to applications for EDTO approvals for EDTO in twin turbine-engined aeroplanes on a route containing a point more than 240 minutes from an adequate aerodrome at 1 engine inoperative cruise speed (in ISA and still air conditions).

       (2)CASA may only give the approval for the specific airframe/engine combination if:

(a) the operator has been operating under a clause 4 or a clause 5 approval, or a combination of these approvals, for at least the 24 months immediately before the approval under this clause would take effect; and

(b) the operator has been operating under a clause 5 approval for the specific air frame/engine combination for at least the 12 months immediately before the approval under this clause would take effect; and

(c) the EDTO approval requirements mentioned in subclauses 4 (2) and (3) and 5 (2) are also complied with.

7 EDTO approvals — aeroplanes with more than 2 engines

       (1)This clause applies to applications for EDTO approvals for EDTO in aeroplanes with more than 2 engines on a route containing a point more than 180 minutes from an adequate aerodrome at 1 engine inoperative cruise speed (in ISA and still air conditions).

       (2)CASA may give the approval only if:

(a) the EDTO approval requirements mentioned in paragraphs 4 (2) (a), (c), (e) and (f) and subclause 4 (3) of this Appendix are complied with; and

(b) the following systems are operational for dispatch:

 (i) the FQIS;

 (ii) if it is required for EDTO — the APU (including electrical and pneumatic supply to its designated capability);

 (iii) a communication system, in addition to any mentioned in the AIP, that is capable of providing direct communication of landline voice quality between the flight crew and air traffic services, and  the flight crew and the operator.

8 EDTO proving flights

       (1)In addition to any other requirements imposed by this Appendix, in considering whether to give an AOC holder an EDTO approval, CASA may require the AOC holder to conduct a proving flight to demonstrate that the AOC holder has the capability and competence to safely conduct and adequately support the intended operation.

       (2) If a proving flight is required, CASA must give the AOC holder a statement of the conditions that will apply for the flight, including the presence of CASA officers as observers on the flight.

       (3) Any condition of the proving flight stated by CASA to be critical to airworthiness, crew workload or performance risks must be successfully demonstrated during the proving flight unless CASA has witnessed a successful demonstration for that particular condition before the proving flight.
