Approximately how long does it take to refuel all tanks?

• A. 5 minutes
• B. 60 minutes
• C. 20 minutes
• D. 10 minutes

Answer: (C)

Refueling time for all tanks is determined by the total fuel capacity and the rate at which fuel can be delivered by ground equipment. An A320 carries about 24,000 kg of fuel when tanks are full (wing tanks plus the center tank). Ground fueling rates are typically around 1,200 kg per minute for hydrant-based systems. Dividing 24,000 kg by 1,200 kg per minute gives roughly 20 minutes. So, approximately 20 minutes is a realistic estimate for filling all tanks. If the rate were much higher, the time would drop toward 5–10 minutes; if the rate were much lower or there were interruptions, it could extend toward an hour.
