Maximum distance from an adequate aerodrome for two-engined aeroplanes without an ETOPS approval PageDiscussionHistoryEditVisual Text <strong>Maximum distance from an adequate aerodrome for two-engined aeroplanes without an ETOPS approval</strong> (a) Unless specifically approved by the Authority in accordance with the Extended range operations with two-engined aeroplanes (ETOPS), an operator shall not operate a two-engined aeroplane over a route which contains a point further from an adequate aerodrome (under standard conditions in still air) than, in the case of: 1. Performance Class A aeroplanes with either: (i) a maximum approved passenger seating configuration of 20 or more; or (ii) a maximum take-off mass of 45 360 kg or more, the distance flown in 60 minutes at the one-engine-inoperative cruise speed determined in accordance with sub- paragraph (b) below; 2. Performance Class A aeroplanes with: (i) a maximum approved passenger seating configuration of 19 or less; and (ii) a maximum take-off mass less than 45 360 kg, the distance flown in 120 minutes or, if approved by the Authority, up to 180 minutes for turbo-jet aeroplanes, at the one-engine-inoperative cruise speed determined in accordance with subparagraph (b) below; 3. Performance Class B or C aeroplanes: (i) The distance flown in 120 minutes at the one-engine-inoperative cruise speed determined in accordance with subparagraph (b) below; or (ii) 300 nautical miles, whichever is less. (b) An 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, based upon the true airspeed that the aeroplane can maintain with one-engine-inoperative. (c) An operator must ensure that the following data, specific to each type or variant, is included in the Operations Manual: 1. the one-engine-inoperative cruise speed determined in accordance with subparagraph (b) above; and 2. the maximum distance from an adequate aerodrome determined in accordance with subparagraphs (a) and (b) above. Note: The speeds specified above are only intended to be used for establishing the maximum distance from an adequate aerodrome. Source: EU-OPS CancelShare this:FacebookTwitterLinkedInEmailPrint
