What does 'Bingo Fuel' refer to?

'Bingo Fuel' specifically refers to a prebriefed fuel state that indicates the minimum amount of fuel required for an aircraft to safely return to its base or a diversion airfield, ensuring that the aircraft has enough fuel to arrive with a normal recovery fuel state. This concept is crucial in flight operations, particularly for military or long-duration flights, as it allows pilots to manage fuel efficiently and make informed decisions regarding their return path.

When a flight plan incorporates 'Bingo Fuel,' it establishes a clear threshold for when the pilot should start their return journey, thereby promoting safety by preventing situations where insufficient fuel could lead to emergency landings or other urgent actions. Understanding 'Bingo Fuel' helps pilots maintain situational awareness regarding fuel management and overall mission success.
