European style rules at Emirates have us landing with:
Final Reserve Fuel + Alternate Fuel + any remaining Contingency Fuel.
Defined.
Final Reserve Fuel = Fuel to fly for 30 minutes at holding speed at 1500 ft. above the destination alternate in standard conditions, calculated with estimated weight on arrival at the alternate.
Alternate Fuel = Fuel for a missed approach from the MDA/DH at the destination, climb to cruising altitude, cruise, descent, approach, and landing with a contingency of 5% added. Not to be less than fuel required for 100 track miles.
Contingency Fuel = The higher of (a) or (b) below:
a. Either:
(i) 5% of the planned trip fuel; or
(ii) 3% of the planned trip fuel provided that an en-route alternate is available. The en-route alternate should be located withinh a circle having a radius equal to 20% of the total flight plan distance, the center of which lies on the planned route at a distance from the destination of 25% of the total flight plan distance, or at 20% of the total flight plan distance plus 50NM, whichever is the greater.
(iii) An amount of fuel sufficient for 20 minutes flying time based upon the planned trip fuel consumption.
b. An amount to fly for 5 minutes at holding speed 1500 ft. above the destination airport in standard conditions.
Up until recently we were using a blanket 5% contingency most of the time. This new change, to come in-line with what the majority of European operators are using, has us now using the 3% contingency most of the time. For a typical flight from Dubai to Singapore or Dubai to Europe ( 7+ hours ) we used to land with roughly 80 to 90 minutes of fuel remaining. Using the 3 % figure that has been cut by 15 minutes to 65 to 75 minutes of fuel remaining.
We always use at least one alternate unless it is a remote destination in which case the fuel would be for 2 hours at normal cruise consumption.
