CAT.OP.MPA.140 Maximum distance from an adequate aerodrome for two-engined aeroplanes without an ETOPS approval

(a) Unless approved by the CAA in accordance with Subpart F of Annex V (Part-SPA), the operator shall not operate a two-engined aeroplane over a route that contains a point further from an adequate aerodrome, under standard conditions in still air, than the appropriate distance for the given type of aeroplane among the following:

(1)  for performance class A aeroplanes with a maximum operational passenger seating configuration (MOPSC) of 20 or more, the distance flown in 60 minutes at the one-engine-inoperative (OEI) cruising speed determined in accordance with point (b);

(2)   for performance class A aeroplanes with an MOPSC of 19 or less, the distance flown in 120 minutes or, subject to approval by the CAA , up to 180 minutes for turbojet aeroplanes, at the OEI cruising speed determined in accordance with point (b);

(3)  for performance class B or C aeroplanes, whichever is less:

(i)  the distance flown in 120 minutes at the OEI cruising speed determined in accordance with point (b);

(ii)  300 NM.

(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 point (a)(2), the operator shall provide evidence that:

(1)  procedures have been established for flight planning and dispatch;

(2)  specific maintenance instructions and procedures to ensure the intended levels of continued airworthiness and reliability of the aeroplane including its engines have been established and included in the operator’s aircraft maintenance programme in accordance with Annex I (Part-M) to Regulation (EU) No 1321/2014, including:

(i)  an engine oil consumption programme;

(ii)  an engine condition monitoring programme.
