What is the hopper tank’s purpose in the Citation Longitude?

• A. To Increase Cargo Capacity
• B. To Store Extra Fuel for Long Flights
• C. To Ensure Essential Feed Is Readily Available Regardless of Attitude
• D. To Cool the Fuel

Answer: (C)

Maintaining a continuous fuel supply to essential systems regardless of the aircraft’s attitude. The hopper tank in the Longitude acts as a small, dedicated fuel reservoir that feeds the essential fuel line, ensuring fuel is available even when the main tank pickups are disadvantaged by extreme pitch or bank angles. This design prevents fuel starvation for critical systems and keeps the engines and other essential components fed under all attitudes. It’s not about increasing cargo capacity, nor simply storing extra fuel for longer range, and it isn’t intended for cooling the fuel.
