A320 Fuel Questions

Refueling time at normal pump pressure is _____ minutes for the wing tanks and _____ minutes for all tanks.

• 15 & 25.
• 17 & 20.
• 15 & 20.
• 25 & 35.

Explanation: Approximate refueling time at nominal pump pressure is 17 minutes for the wing tanks and 20 minutes for all tanks (without an additional center tank).

The Fuel Used indication on ECAM is reset:

• Manually by the pilot.
• Automatically at engine start on the ground.
• Automatically at electric power up of the aircraft.

Explanation: The Fuel Used indication on ECAM is automatically reset when an engine is started on the ground.

What is the minimum fuel quantity for take-off?

• 1,000 kg
• 1,200 kg.
• 1,500 kg
• 2,000 kg

Explanation: The minimum fuel quantity for takeoff is 1,500 kg.

From which tanks will fuel gravity feed?

• Outer cell of the wing tanks, inner cell of the wing tanks, and/or center tank.
• Inner cell of the wing tanks, and center tank.
• Outer cell of the wing tanks, and inner cell of the wing tanks.
• The center tank only.

Explanation: The center tank has no suction valves, so it can never gravity feed. Gravity feeding instead flows from the outer wing cells (which drain into the inner cells) and from the inner wing cells (which feed the engines through suction valves if the inner tank pumps fail).

What indication will you see on the overhead fuel panel if the center tank has more than 250 kilograms of fuel and the left or right wing tank have less than 5,000 kilograms.

• Auto feed fault.
• Fuel imbalance.
• Mode select fault.
• Fuel - Auto feed fault.

Explanation: This condition (center tank above 250 kg while a wing tank is below 5,000 kg) is exactly what triggers the amber FAULT light and ECAM caution on the MODE SEL pushbutton - a mode select fault.

Fuel can be transferred from tank to tank:

• Only on the ground.
• In flight if the fuel X FEED push button is selected OPEN.
• In flight if the fuel X FEED push button is selected OPEN and center tank MODE SEL push button is selected to MAN.
• Fuel can never be transferred.

Explanation: The X FEED valve only lets one tank's pumps feed both engines, or both sides feed one engine - it redirects which pumps feed which engine rather than literally moving fuel from one tank to another. The only genuine tank-to-tank transfers (outer-to-inner, and center/ACT-to-center) happen automatically based on tank level, not through a pilot-selected MODE SEL or X FEED combination.

Refueling is possible if the aircraft batteries are the only source of power.

• True
• False

Explanation: The aircraft can be refueled when only battery power is available.

Fuel - Description (Refueling and Defueling)

The fuel quantity indication on ECAM for the outer cell is boxed amber if:

• One transfer valve fails to open.
• Outer cell fuel temperature is high.
• Both transfer valves fail to open when inner cell is at low level.

Explanation: The outer cell's fuel quantity indication is boxed amber specifically when both transfer valves fail to open while the inner cell is at low level.
