Refer to figure.
​​​​​1. Firstly, calculate the Fuel flow at 5 000 ft for Mass 7 900 kg:

1. Enter the graph from pressure altitude 5 000 ft.
2. Move horizontally to the right until crossing the mass 7 900 kg (between 7.5 and 8.0 solid lines).
3. Continue vertically down and read Fuel Flow: 450 kg/hr

2. Secondly, calculate the cruise time to cover the cruise distance from TOC to TOD: Cruise Distance / GS = 95 NM / 147 kt = 0.646 hr.

3. Therefore, the fuel required in kg to cover the cruise distance from TOC to TOD is: Cruise time x Fuel Flow = 0.646 hr x 450 kg/hr = 291 kg.

4. According to AMC3 CAT.OP.MPA.150(b) - Fuel policy for helicopters:

The operator should base the company fuel policy, including calculation of the amount of fuel to be carried, on the following planning criteria:

(a) The amount of:

(1) taxi fuel: 25 kg;

(2) trip fuel: 65 kg + 291 kg + 50 kg = 406 kg, which should include fuel:

(i) for take-off and climb: 65 kg;

(ii) from top of climb to top of descent: 291 kg;

(iii) from top of descent until landing at the destination, 50 kg;

(3) contingency fuel, which should be for VFR flights in a non-hostile environment, 5 % of the planned trip fuel: 5% x 406 kg = 20.3 kg ;

(4) alternate fuel: 0 kg;

(5) final reserve fuel: 80 kg;

(6) extra fuel: N/A.

5. Thus, the fuel that must be loaded before start-up is: 25 kg + 406 kg + 20.3 kg + 80 kg = 531 kg.
