The booster pump is commonly used during which flight phase to ensure fuel supply?

Explanation:
The main idea here is why an extra fuel pump is used when fuel demand is at its peak. The booster pump provides positive pressure in the fuel lines and helps prime the system so the engine-driven pump receives a steady, adequate flow. This is especially important during takeoff and landing, when the engines demand maximum fuel flow and any drop in pressure could cause the engine to lose power or surge. The booster pump ensures reliable fuel supply during these high-demand phases. In cruise, descent, or when parked, the engine-driven pump alone usually provides enough pressure, so the booster pump isn’t routinely required.
