Study Notes
Pressure Refueling Modes
- There are 3 modes of pressure refueling: manual, automatic, and override.
Manual Refueling
- Requires pre-calculation of fuel distribution
- Refueling valves are manually controlled through a control panel.
- Requires constant monitoring of fuel quantities in the tanks.
Automatic Refueling
- Uses a fuel quantity control computer to calculate fuel distribution based on block fuel preselection.
- Automatically controls the refueling valves for accurate fuel and distribution.
- Benefits: safe, reduces workload, stops refueling at preselected fuel.
- The standard mode on modern aircraft.
Override Refueling
- Used when electrical power to the refueling valves is unavailable.
- Refueling valves are opened by a mechanical override on the refueling valves, bypassing the electrical system.
