AMC1 CAT.OP.MPA.182 Fuel/energy scheme — aerodrome selection policy
— aeroplanes
BASIC FUEL SCHEME — TAKE-OFF ALTERNATE AERODROME
The take-off alternate aerodrome should not be farther from the departure aerodrome than:
(a) for two-engined aeroplanes:
(1) 1-hour flight time at an one-engine-inoperative (OEI) cruising speed according to the AFM in ISA and still-air conditions using the actual take-off mass; or
(2) the extended-range twin operations (ETOPS) diversion time that is approved in accordance with Subpart F of Annex V (Part-SPA) to Regulation (EU) No 965/2012, subject to any minimum equipment list (MEL) restriction, up to a maximum of 2-hour flight time at OEI cruising speed according to the AFM in ISA and still-air conditions using the actual take-off mass; and
(b) for three- or four-engined aeroplanes, 2-hour flight time at an all-engines-operating cruising speed according to the AFM in ISA and still-air conditions using the actual take-off mass;
(c) for operations approved in accordance with Annex V (Part-SPA), Subpart L SINGLE-ENGINED TURBINE AEROPLANE OPERATIONS AT NIGHT OR IN IMC (SET-IMC), 30 minutes flying time at normal cruising speed in still-air conditions, based on the actual take-off mass;
(d) in the case of multi-engined aeroplanes, if the AFM does not contain an OEI cruising speed, the speed to be used for calculation shall be that which is achieved with the remaining engine(s) set at maximum continuous power.
EASA Fuel Planning: Take-off Alternate Aerodrome Selection Aeroplanes must select a take-off alternate aerodrome within a specific flight time. This time varies based on the number of engines: one hour for two-engine aircraft (potentially extended for ETOPS), two hours for three/four-engine aircraft, and 30 minutes for SET-IMC operations. Speed calculations use AFM data.
