What does B + 1000 on the HUD indicate?

• A. Current fuel state is 1,000 pounds over the set bingo
• B. Fuel has 1,000 pounds remaining
• C. Bingo fuel is 1,000 pounds
• D. The cockpit is at 1,000 feet altitude

Answer: (A)

The main idea is that the HUD shows fuel relative to a defined bingo fuel. Bingo fuel is the minimum fuel amount set for a safe landing with required reserves. The letter B on the display is shorthand for that bingo value, and the + 1000 indicates how far above that bingo value your current fuel is. So, B + 1000 means your current fuel on board is 1,000 pounds more than the bingo fuel. It’s not the remaining amount, not the bingo fuel itself, and not an altitude reading. For example, if bingo is 5,000 pounds, B + 1000 would display as 6,000 pounds of fuel on board.
