(ii)  
a maximum take-off mass of 45 360 kg or more,

the distance flown in 60 minutes at the one-engine-inoperative (OEI) cruising speed determined in accordance with (b);
(2)  for performance class A aeroplanes with:
(i)  
an MOPSC of 19 or less; and

(ii)  
a maximum take-off mass less than 45 360 kg,

the distance flown in 120 minutes or, subject to approval by the competent authority, up to 180 minutes for turbo-jet aeroplanes, at the OEI cruise speed determined in accordance with (b);
(3)  for performance class B or C aeroplanes:
(i)  
the distance flown in 120 minutes at the OEI cruise speed determined in accordance with (b); or

(ii)  
300 NM, whichever is less.

(b)  
The operator shall determine a speed for the calculation of the maximum distance to an adequate aerodrome for each two-engined aeroplane type or variant operated, not exceeding VMO (maximum operating speed) based upon the true airspeed that the aeroplane can maintain with one engine inoperative.

(c)  
The operator shall include the following data, specific to each type or variant, in the operations manual:

(1)  
the determined OEI cruising speed; and

(2)  
the determined maximum distance from an adequate aerodrome.

(d)  
To obtain the approval referred to in (a)(2), the operator shall provide evidence that: 

(1)  
the aeroplane/engine combination holds an extended range operations with two-engined aeroplanes (ETOPS) type design and reliability approval for the intended operation;

(2)  
a set of conditions has been implemented to ensure that the aeroplane and its engines are maintained to meet the necessary reliability criteria; and

(3)  
the flight crew and all other operations personnel involved are trained and suitably qualified to conduct the intended operation.

CAT.OP.MPA.145 Establishment of minimum flight altitudes
(a)  
The operator shall establish for all route segments to be flown: 

(1)  
minimum flight altitudes that provide the required terrain clearance, taking into account the requirements of CAT.POL; and

(2)  
a method for the flight crew to determine those altitudes.

(b)  
The method for establishing minimum flight altitudes shall be approved by the competent authority.

(c)  
Where the minimum flight altitudes established by the operator and a State overflown differ, the higher values shall apply.

CAT.OP.MPA.150 Fuel policy
(a)  
The operator shall establish a fuel policy for the purpose of flight planning and in-flight replanning to ensure that every flight carries sufficient fuel for the planned operation and reserves to cover deviations from the planned operation. The fuel policy and any change to it require prior approval by the competent authority.
