Practical aviation fuel training — instruction, guided practice, practical assessment, competence decisions and certificates, with every module traceable to its source procedure.
Complete the monthly examination of filtration, deadman control, hoses, strainers and emergency equipment.
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.
TEST AT MAXIMUM FLOW RATE, DURING A WEEKLY RECIRCULATION?
Procedure 3, line 20
Test at maximum flow rate during the weekly recirculation.
Reason The source states this as a question — “TEST AT MAXIMUM FLOW RATE, DURING A WEEKLY RECIRCULATION?”. Confirm whether the test is required during the weekly recirculation.
OPENING TIMED FROM START OF FLOW TO MAXIMUM, SECONDS IF BELOW 2000LPM
Procedure 3, line 21
No suggestion — confirm the intended requirement.
Reason The source reads “OPENING TIMED FROM START OF FLOW TO MAXIMUM, SECONDS IF BELOW 2000LPM” — the number of seconds is missing. Confirm the acceptance time.
OVERSHOOT FROM RELEASE TO ZERO FLOW, MAX IOOLTS PER HOSE IF BELOW 2000LPM
Procedure 3, line 23
Maximum 100 litres per hose below 2000 litres per minute.
Reason The source reads “MAX IOOLTS PER HOSE IF BELOW 2000LPM”. The limit is OCR-damaged — confirm the maximum overshoot.
CHECK INTERMITANT TIMING FROM START OF FLOW TO TIMEOUT, 2 MINS MAX
Procedure 3, line 24
Check the intermittent timing from start of flow to timeout, 2 minutes maximum.
Reason Source wording is misspelled (“INTERMITANT”) — confirm the intended requirement.
BEFORE ANY PRODUCT FLOW SHOULD READ
Procedure 3, line 28
Before any product flow the gauge should read zero.
Reason The source line ends without a value — “BEFORE ANY PRODUCT FLOW SHOULD READ”. Confirm the reading required before flow.
COUPLING FACE, LUGS, SEAL FOR DAMAGE, WEAR, LEAKS ETC.
Procedure 3, line 33
No suggestion — confirm the intended requirement.
Reason The source ends the list with “ETC.” — confirm what else must be checked on the ground coupling.
FIRST AID KIT, SPILL KIT, CHECK CONTE-NETS
Procedure 3, line 61
First aid kit and spill kit: check contents.
Reason Source wording is damaged (“CHECK CONTE-NETS”) — confirm the intended requirement.
