When an engine receives fuel from a tank that is not its designated tank, this process is called:

Explanation:
Crossfeeding means feeding an engine from a different fuel tank than the one normally assigned to it. In aircraft with multiple tanks, each engine usually draws from a designated tank, but a crossfeed valve can connect the engine’s feed line to another tank so fuel can flow to that engine when necessary—helping balance fuel across tanks or keep an engine supplied if its own tank is low. This isn’t about dumping fuel to reduce weight (jettison), nor about fueling with engines running (hot refueling), nor about keeping tanks isolated (separation/isolation).
