• Jet pumps (ejector pumps)

• Electrical pump

• Small scavenge / electrical pumps

Surge Protection Valves’ purpose is ....

• Prevent fuel surges or sloshing

• Allow fuel to flow in one direction only

• Allow fuel transfer between tanks

• Manage air pressure inside tanks

• Vent surge tanks

Why does each wing tank contain a collector cell?

• To increase overall fuel capacity

• To prevent fuel freezing in cold temperatures

• To keep fuel pump inlets immersed and provide negative “g” protection

• To balance fuel weight distribution

Which has the purpose of remove excess fuel from vent surge tanks and return it to the main tanks?

• Refuel/Defuel Pumps

• Centre Tank Pumps

• Scavenge Pumps

• Vent Surge Tank Pumps

Which valve allows fuel to flow in only one direction, preventing backflow?

• Non-Return Valve (Check Valve)

• Surge Protection Valve

What is the primary purpose of a fuel shutoƯ valve?

• Balance fuel distribution between tanks

• Isolate fuel flow in emergencies or maintenance

• Prevent excessive pressure buildup in tanks

• Control fuel surges during flight

Which valve prevents excessive pressure buildup inside fuel tanks?

• Vent Valve

• Pressure Relief Valve

• Surge Protection Valve

• Refuel/Defuel Valve
