LOADING
Practical aviation fuel training — instruction, guided practice, practical assessment, competence decisions and certificates, with every module traceable to its source procedure.
Refuel the aircraft under control, monitoring the equipment and the zone throughout.
The source wording is unclear, misspelled or uses an unverified unit. The original is kept as it stands — an authorised person confirms the final wording before the module can be published.
MONITOR STEPS FOR WING SETTLE AFTER I,OOOLTS HAS CLEARED HOSE, FILTER & PIPING SLOW/STOP DELIVERY TO PERFORM VISUAL CHECK
Procedure 9, line 23
After 1,000 litres has cleared the hose, filter and piping, slow or stop delivery to perform the visual check.
Reason The source reads “AFTER I,OOOLTS HAS CLEARED HOSE, FILTER & PIPING” — the volume is OCR-damaged. Confirm the quantity that must clear before the check.
ANY DIFFERENCE GREATER THAN 2 MUST BE INVESTIGATED, EXPLAINED CONTINUALLY MONITOR FUELING EQUIPMENT & ZONE FOR HAZARDS, IGNITION SOURCES, VEHICLE OBSTRUCTIONS
Procedure 9, line 28
Any difference greater than 2 psi must be investigated and explained.
Reason The source states “ANY DIFFERENCE GREATER THAN 2” without a unit, and the line runs into the next requirement. Confirm the unit and the threshold.
Position, PPE and equipment, manual handling, risk assessment and safety awareness
Why The preparation decides how safely everything that follows can be done.
Expected Correct position, correct PPE, equipment present, hazards identified.
If it fails Correct the position or fetch the missing equipment before continuing.
Fuel gauge panels operated only where the fuelling contract allows it
Why Operating a panel without the agreement in place is outside the contract.
Source: procedure 9, line 14 — “OPERATE FUEL GAUGE PANELS ONLY IF AGREEMENT IN PLACE WITH FUELLING CONTRACT”
Check the gauges, note the fuel already on the aircraft and calculate the expected uplift
Why The expected uplift is what tells you if something is wrong during the delivery.
Source: procedure 9, line 15 — “VISUALLY CHECK FUEL GAUGES, NOTE AMOUNT ALREADY ON AIRCRAFT, CALCULATE EXPECTED UPLIFT”
Select the vehicle and meter used
Permission obtained from the crew, engineer or fuelling overseer before starting
Why Fuelling without permission can conflict with work happening on the aircraft.
If it fails Do not start. Wait for permission.
Source: procedure 9, line 17 — “OBTAIN PERMISSION FROM CREW/ENGINEER/FUELLING OVERSEER TO START FUELLING AIRCRAFT”
Meter zeroed and the digital meter started
Source: procedure 9, line 18 — “CHECK METER ZEROED, 'START' DIGITAL METER”
Open the footvalve, activate the pump and open the hose fuelling valve
Source: procedure 9, line 19 — “OPEN FOOTVALVE, ACTIVATE PUMP, OPEN HOSE FUELING VALVE”
Deadman operated and reset every 2 minutes
Why The deadman is what stops the delivery if the operator is incapacitated.
Expected Held during flow and reset within the timeout.
If it fails Stop the delivery if the deadman does not hold or reset correctly.
Source: procedure 9, line 20 — “OPERATE DEADMAN, RESET EVERY 2 MINUTES”
Once flow is established, increase pump speed to the maximum flow rate
Source: procedure 9, line 21 — “WHEN PRODUCT FLOW ESTABLISHED INCREASE PUMP SPEED TO MAX FLOW RATE”
Hose, coupling and aircraft tank vents monitored for leaks, drips and bulges
Source: procedure 9, line 22 — “MONITOR HOSE, COUPLING, AIRCRAFT FUEL TANK VENTS FOR LEAKS, DRIPS, BULGES”
Steps monitored for wing settle, and the delivery slowed or stopped for the visual check once the first product has cleared the hose, filter and piping
Why The first product through carries anything that was standing in the system.
Expected Delivery slowed or stopped and a visual check performed.
If it fails If the visual check fails, stop fuelling and inform the supervisor.
Source: procedure 9, line 23 — “MONITOR STEPS FOR WING SETTLE AFTER I,OOOLTS HAS CLEARED HOSE, FILTER & PIPING SLOW/STOP DELIVERY TO PERFORM VISUAL CHECK”
Fuelling continued and maximum flow re-established only after the visual check passes
Source: procedure 9, line 24 — “IF VISUAL CHECK PASSES CONTINUE FUELLING, RE-ESTABLISH MAXIMUM FLOW RATE”
All gauges and the meter on the control panel monitored
Source: procedure 9, line 25 — “MONITOR ALL GAUGES AND METER ON FUELLING VEHICLE CONTROL PANEL”
Flow rate recorded on the logsheet
Source: procedure 9, line 26 — “RECORD FLOW RATE, DIFFERENTIAL PRESSURE GAUGE READING ON LOGSHEET”
Differential pressure gauge reading recorded on the logsheet
Source: procedure 9, line 26 — “RECORD FLOW RATE, DIFFERENTIAL PRESSURE GAUGE READING ON LOGSHEET”
Differential pressure compared against the previous reading
Source: procedure 9, line 27 — “CHECK D.P. READING VERSUS PREVIOUS”
Any difference greater than 2 investigated and explained
Why A jump in differential pressure is the filter telling you something changed.
If it fails Do not continue until the difference is explained.
Source: procedure 9, line 28 — “ANY DIFFERENCE GREATER THAN 2 MUST BE INVESTIGATED, EXPLAINED CONTINUALLY MONITOR FUELING EQUIPMENT & ZONE FOR HAZARDS, IGNITION SOURCES, VEHICLE OBSTRUCTIONS”
Fuelling equipment and zone continually monitored for hazards, ignition sources and vehicle obstructions
Source: procedure 9, line 28 — “ANY DIFFERENCE GREATER THAN 2 MUST BE INVESTIGATED, EXPLAINED CONTINUALLY MONITOR FUELING EQUIPMENT & ZONE FOR HAZARDS, IGNITION SOURCES, VEHICLE OBSTRUCTIONS”
Visual contact maintained with the overseer; fuelling stopped if the view is blocked
Why The overseer is how an emergency reaches you.
If it fails Stop fuelling until visual contact is restored.
Source: procedure 9, line 29 — “MAINTAIN VISUAL CONTACT WITH OVERSEER IN CASE OF EMERGENCY, IF BLOCKED STOP FUELLING”
Pump speed adjusted to match the flow when a tank fills and closes down
Source: procedure 9, line 30 — “ADJUST PUMP SPEED TO MATCH FLOW RATE WHEN A TANK IS FULL AND CLOSES DOWN”
When fuelling is complete, release the deadman, stow it safely and close the hose fuelling valve
Source: procedure 9, line 31 — “WHEN FUELING COMPLETE, RELEASE DEADMAN, STOW SAFELY, CLOSE HOSE FUELING VALVE”
Aircraft gauges match the requested figure; topped up if short
Source: procedure 9, line 32 — “CHECK AIRCRAFT FUEL GAUGES MATCH REQUESTED FUEL FIGURE, TOP UP IF SHORT”
Release hose pressure by increasing the pre-set figure or manually opening a tank valve
Source: procedure 9, line 33 — “RELEASE HOSE PRESSURE BY INCREASING PRE-SET FIGURE OR MANUALLY OPEN A FUEL TANK VALVE”
Delivered quantity recorded on the logsheet and customer invoice
Source: procedure 9, line 34 — “RECORD DELIVERED AMOUNT IN LITRES ON LOGSHEET & CUSTOMER INVOICE”
New meter reading checked
Source: procedure 9, line 35 — “CHECK NEW METER READING”
Uplift or invoice passed to the customer, signature obtained and a copy retained
Source: procedure 9, line 36 — “PASS UPLIFT/INVOICE TO CUSTOMER, OBTAIN SIGNATURE, RETAIN INVOICE COPY”
Close the footvalve and switch the pump off or to rewind the hose
