3.3.2. A340-500/-600
A340-500 and A340-600 have similar refueling sequences:
.  
Inner tanks 1,2,3 and 4 up to up to 3000 kg per tank, Total fuel = 12000 kg (to fill in the collector cells)

.  
Outer tanks up to up to 4500 kg per tank, Total fuel = 21000 kg

.  
Inner tanks 1, 2, 3 and 4 up to up to 18200 kg per tank, Total fuel = 81800 kg 

.  
Inner tanks 2 and 3 up to 25700 kg per tank, center tank up to 17000 kg and trim tank up to 2400 kg, Total fuel = 116200 kg

.  
Center tank up to 40000 kg and trim tank up to 5900 kg, Total fuel = 142700 kg

.  
A340-500: rear center tank up to 14956 kg, Total fuel = 157656 kg 

.  
Inner tanks 1, 2, 3 and 4 (full), outer tanks (full), center tank (full), trim tank (full) and for A340-500: rear center tank (full)
