Hi Gambit,
Here is a late referenced answer:

3.1 Taxi fuel;
3.2 Trip Fuel;
3.3 Contingency Fuel calculated in accordance with sub-paragraph 1.3 above;
3.4 Additional Fuel if required, but not less than:
(a) For aeroplanes with reciprocating engines, fuel to fly for 45 minutes plus 15% of the flight time planned to be spent at cruising level, or two hours, whichever is less; or
(b) For aeroplanes with turbine engines, fuel to fly for two hours at normal cruise consumption after arriving overhead the destination aerodrome, including final reserve fuel; and
3.5 Extra Fuel if required by the commander.
So for isolated aerodromes, your addn fuel includes your final reserve fuel.
Cheers
