EDTO alternate at the approved 1 engine inoperative cruise speed assuming an engine failure at the most critical point followed by a descent to the 1 engine inoperative cruise altitude;

(b) on reaching the EDTO alternate aerodrome, the aeroplane must have sufficient fuel for the pilot in command to:

 (i) hold for 15 minutes at 1 500 feet above the aerodrome elevation; and

           (ii) conduct an instrument approach and land;

(c) if the AOC holder is using a wind forecast model acceptable to CASA, to allow for errors in wind forecasting, the AOC holder must add a 5% wind speed factor (i.e. as an increment to a headwind or as a decrement to a tailwind) on the actual or forecast wind used to calculate the fuel requirements of paragraph (a);

(d) if the AOC holder is using a wind forecast model that is not acceptable to CASA, to allow for errors in the model's wind data, the AOC holder must ensure that the aeroplane carries an additional 5% of the fuel calculated under the requirements of paragraph (a);

(e) when calculating the fuel required under paragraph (a), the AOC holder must compensate for whichever is the greater of:

           (i) the effect of airframe icing for 10% of the time during which icing is forecast (including taking into account the fuel that would be used by the use of engine and wing anti-ice during the same period); or

           (ii) the fuel that would be used by use of engine anti-ice, and if appropriate wing anti-ice, for the entire time during which icing is forecast;

(f) when calculating the fuel required under subparagraphs (a) (i) to (a) (iii), the AOC holder must increase the fuel supply by 5% as a performance deterioration allowance unless the operator has a program established to monitor aeroplane in-service deterioration in cruise fuel burn performance, and includes in fuel supply calculations fuel sufficient to compensate for any such deterioration;

(g) if an APU is a required power source, the operator must account for its fuel consumption during all phases of flight where it may be used;

(h) any additional fuel consumption due to the minimum equipment list or the configuration deviation list.

Note   A wind aloft forecasting distributed worldwide by the World Area Forecast System (WAFS) is an example of a wind forecast model acceptable to CASA.

7 Standard EDTO en route alternate aerodrome planning minima

       (1)Unless CASA approves otherwise in accordance with clause 8, for flight planning and aeroplane dispatch, the AOC holder must ensure that the requirements of an EDTO alternate aerodrome are met by satisfying the criteria of 1 of the aerodrome planning minima set out in Table 1.
