For this question, we must consider the quantity of the inner tanks as specified in the question. The values stated in the annex represent the total usable fuel capacities and should only be used when the question explicitly mentions “FULL.”

1. Trim Tanks
The failure of the trim tank pump means that the engines will no longer be fed from the trim tank. Therefore, the fuel available for the rest of the flight is from the inner and outer tanks.

2. Outer Tanks
Since the outer tanks are FULL, we can determine the amount of fuel available from them based on the usable fuel they can hold, as given in the annex.

• Each outer tank can hold 2865 kg of fuel.
• Since there are two outer tanks (left and right), the total fuel available from them is: 2865 kg x 2 = 5730 kg

3. Inner Tanks
Although each inner tank can hold 32 970 kg, the question specifies that there is 12 500 kg of fuel in each inner tank. Therefore,

• The total fuel available from the two inner tanks (left and right) is : 12 500 kg x 2 = 25 000 kg

4. TOTAL FUEL
Therefore, the total fuel available for the remainder of the flight is:

• Total fuel (kg) = Fuel from outer tanks (kg) + Fuel from inner tanks (kg)
• Total fuel = 5730 kg + 25 000 kg
• Total fuel = 30 730 kg
