What does a pilot's declaration of minimum fuel indicate?

A pilot's declaration of minimum fuel serves to inform air traffic control that the aircraft is nearing the minimum fuel threshold required to complete the intended flight. This declaration implies that while the aircraft is not in an emergency situation, the pilot cannot accept any undue delay in landing at the destination. The pilot may need to prioritize their landing over other flight operations, as delays could compromise their ability to complete the flight safely.

This declaration is essentially a warning of the need for expeditious handling to ensure the aircraft lands with adequate fuel reserves remaining, but it does not imply that the pilot is facing an immediate crisis or emergency. By making the declaration, the pilot allows air traffic control to provide necessary assistance and possibly expedite procedures without escalating the situation to emergency status.
