Study Notes
AAFARS Overview
- AAFARS stands for Advanced Aviation Forward Area Refueling System.
- Designed to enhance aircraft operational flexibility in forward areas.
Refueling Capacity
- Maximum capacity allows for 4 aircraft refueling points.
- Refueling rate at each point is typically 55 gallons per minute (GPM) under standard operation.
- Independently, each refueling point can achieve a rate of 90 GPM.
Pump and System Specifications
- Utilizes a 225 GPM pump with an operating speed of 3400 RPM and a maximum pumping RPM of 3600 RPM.
- Fuel storage (F/S) is designed to handle flows up to 240 GPM.
Hose Configurations
- Equipped with ten 2" x 7' suction hoses for effective fuel sourcing.
- Contains two 2" x 12' collapsible recirculation hoses for system adjustments.
- One 2" x 50' recirculation hose and four 2" x 50' discharge hoses are included, with one discharge hose at each refueling point.
- A single 3" x 6' discharge hose connects the pump to the fuel storage system.
Nozzle Types and Operations
- Total of 13 nozzles available, including Single Port (D-1), CCR, open port, and fuel/oil servicing nozzle.
- Defueling capability is measured at 13-15 gallons per minute.
Fueling Methods
- Fuel can be pumped electrically or manually, offering flexibility depending on the situation.
- Requires a warm-up time of approximately 5 minutes for the pump before operation.
- Recirculation duration lasts for 15 minutes to ensure system readiness.
Operational Procedures
- Full recirculation is advised on or before the morning Aqua-Glo test or in response to a bag tear.
- Starting the pump involves pulling the manual starter 8 times, increasing to 12 pulls if the temperature is below 20 degrees Fahrenheit.
Safety and Grounding
- The system includes five grounding rods to ensure safe operation and prevent static discharge during fueling activities.
