How is FUEL STATE typically expressed?

FUEL STATE is typically expressed in time or pounds because this method provides a clear indication of the amount of fuel available versus the time an aircraft can remain airborne. Expressing fuel in time allows operators to assess the duration the aircraft can fly before needing to refuel, while pounds give a quantitative measure of fuel weight, which is critical for flight planning and safety assessments.

Using time or pounds as a metric facilitates better situational awareness for pilots and crew, helping them make informed decisions during flight operations. The other options do not accurately reflect the standard way of conveying fuel state; geographical coordinates relate to location, feet or meters pertain to altitude, and nautical miles indicate distance traveled, none of which directly inform about the fuel available.
