What is the limitation regarding center tank fuel?

• A. Takeoff With Center Tank Fuel Supplying The Engines Is Prohibited (A320CEO)
• B. Center Tank Fuel Must Be Used On All Flights
• C. Center Tank Fuel Cannot Be Used At All
• D. Center Tank Fuel Can Be Used Only Under Certain Conditions

Answer: (A)

The limitation being tested is that engines must not be fed from the center fuel tank during takeoff on the A320CEO. This restriction exists because the takeoff phase is the most demanding for a reliable fuel feed, and the center tank’s pumping and crossfeed arrangement isn’t approved for providing engine fuel during that critical moment. By ensuring the engines are fed from the wing tanks during takeoff, the pilots avoid a potential fuel-pressure or supply issue during acceleration and rotation. Center tank fuel is available for use later in flight to extend range or balance fuel distribution, but it cannot supply the engines during takeoff. This makes the other options misleading: the center tank isn’t mandated for all flights, it isn’t categorically unusable, and the limitation isn’t just “under certain unspecified conditions”—it specifically prohibits center-tank feeding of the engines during takeoff.
