If your ZFW is 61,500kg (MAC: 29%), what is your TOW and % MAC respectively?
You need to account for the fuel in the AUX tank.
This question is checking if you know the fuel distribution requirements and how to account for abnormal loads. The trap here is if you don't apply the change because of the fuel in the AUX tank vs normal loading it will throw off your %MAC at TOW. On the fuel curve you need to calculate the MAC change for the 18t loaded normally, and 1t in the Aux tank.
