What does the term "BINGO" refer to in the context of FUEL STATE?

The term "BINGO" in the context of fuel state refers to the minimum fuel required for an aircraft to return to a safe landing point, typically the starting base or a designated alternate airfield. This is a crucial point in flight operations as it provides pilots with a clear indication of when they should begin their return to ensure that they have enough fuel for landing safely. Knowing the BINGO fuel level allows for effective planning and helps in managing fuel consumption during flight, ensuring that pilots are prepared for unexpected situations that may require them to divert or return early. Recognizing the BINGO fuel status is vital for flight safety and operational efficiency.
