Record Fluid Servicing
Explanation
In order to record fluid servicing, the technician should first select the predefined fluid servicing type and
then record uptakes by adding the relevant quantities.
After adding quantities to fluid servicing records, the technicians can submit the record.
Prerequisites
- Fluid Servicing Types must be defined for the aircraft on the Aircraft Fluid Servicing
Definition page.
- Once the flight is completed, the current usages of the inventory need to be synchronized from Maintenix to
calculate the Usage Delta (TSN Delta).
System Effects
- Fluid servicing records are added to Fluid Servicing Record page and the Fluid
Consumption page.
- For each fluid uptake record, the Fluid Consumption Rate is calculated as follows:
- Fetch the current usage (TSN) value for the same inventory and usage type (Operator Time Parameter in
Fluid Definitions).
- Fetch the previous TSN value from a previous Fluid Recording Detail Record belonging to the same
Assembly, Fluid Definition, Inventory, Config Slot Position and the TSN delta is not null (calculated record)
as well as the TSN value is not the same (so there is a delta) - fetch the first result when ordered by the
recorded date.
- Calculate delta between current usage and previous usage.
- Get Any Previous Uplifts where there is no delta between usage TSN values for the current Assembly, Fluid
Definition, Inventory, Config Slot Position.
- If Current Recorded Uptake > 0 then Sum the results from the previous uplifts, If not rate will be
0.
- If Uptake > 0 and the TSN delta > 0 then Calculate rate as Uptake/TSN Delta, If not rate
is 0.
- The Rate, TSN Delta, TSN Usage value used for each calculation will be stored.
- Oil Status is then fetched for the calculated rate from the Thresholds defined, The priority that will be
considered is as follows and the Oil Status of the Threshold with the first matching criteria is what will be
saved ;
- Serial Specific Thresholds (If there is one defined for the Serial Number of the Inventory)
- Part Specific Thresholds (If there is one defined for the Part Number of the Inventory)
- Operator Specific Thresholds (If there is one defined for the Operator Code of the Aircraft of the
Inventory)
- General Threshold
