An “Expand” icon is provided before the “Open Orders”.

When you click this icon, all execution documents such as “Visit Packages” and “Technical Logs” are listed as individual line items in the left pane.

You can further expand these visit packages and technical logs so as to list the work units allocated to each of them. The system retrieves and lists all the Work Units, Discrepancies or Maintenance Reports in “Allocated” status, under the specific execution document numbers to which they are allocated.

For example, there could be five work units associated to an aircraft such as: WU1, WU2, WU3, WU4 and WU5. Out of the five work units listed here, WU1 and WU5 are not allocated to any execution document. WU2 is allocated to Visit Package, WU3 is allocated to Technical Log, and WU4 to Hangar Work Order. The system will list WU1 and WU5 under “Work Unit Details” cluster, WU2 and WU4 under Visit Package, and WU3 under Technical log.

An “Expand” icon is also displayed before”Visit Packages” and “Technical Logs”. When you click on it, the specific documents are displayed.

Display of execution document details in the right pane

A bar spanning across the duration of the execution document is displayed in the right pane, for execution documents in the left pane. When you try to drag the 'Technical Log' bar in the Gantt chart, the following take place:

• The “Plan Start Date & Time” and the “Plan End Date & Time” of the Technical Log are dynamically updated for the Technical Log, and for the Work Units listed under the Technical Log.

• The “Plan End Date & Time” of the Work Unit is calculated, based on the "Estimated Elapsed Time" of the work units.

You can plan the maintenance of the aircraft, using either the (i) “Planning Details Chart” or (ii) multiline

Using the “Planning Details Chart” to plan maintenance

The planning details chart has the following features:

• The “current date” and the “search date” are shown as dotted vertical lines in “Green” and “Pink” colours

• The user can change the “Scheduled Start Date” and “Schedule End Date” for the work units by shifting the position of the bar along the right pane. The duration of the work unit can also be changed by keeping either the “Start Date” or “End Date” as constant.

Note: If the work unit is allocated to any execution document, you cannot modify the planned start date & time and planned end date & time as the work unit bar cannot be dragged along the Gantt Chart.

• The details that are changed due to shifting of the bar such as “Start Date”, “End Date”, and “Duration” are displayed dynamically in a tool-tip over the bar.

• The user can change the “Schedule Start Date” and “Schedule End Date” , by double clicking on the bar. A pop-up  window with all the details of the work unit is displayed.

• Overdue work units are represented with a “Yellow” background.

• On clicking the execution document, all the constituent work units are displayed as solid lines connecting the document and the work units. The lines will disappear, if the user clicks again on the execution document.

• Click the “Plan Jobs” pushbutton, to plan the jobs.

You can plan the maintenance of the aircraft, using either the (i) “Planning Details Chart” or (ii) multiline

Using the “Work Unit Details” multiline to plan maintenance

• Enter the following in the “Planning Details Chart” group box

Note: If this field is left blank, then system saves the details of the work units selected in the chart in the “Central Planning” business component.

• Enter the following:

The system displays the following:

To “Assign” the work units

• Select “Assign” from the “Action” drop-down list box. Ensures that the selected work unit is not a “'Non Routine Item”, i.e. Unplanned Work Unit.

• Select an unassigned work unit (A work unit which is not assigned to any execution document) from the “Planning Details Chart”. Only one execution document must be selected, either “Visit Package” or “Technical Log”.

•  Select an execution document to which the selected work units must be assigned.

•  Click the “Plan Jobs” push button to assign the work units to the selected document.

The work unit is assigned to either the visit package or the technical log. Once the work units get assigned to either the visit package or the technical log, the system moves the work units to the corresponding visit package/technical log numbers that are listed under the “Open Order” group box in the Gantt chart.

If any of the Work Unit(s) or Discrepancies or Maintenance Report(s) are getting assigned to a Technical Log #, the system carries out the following:

• Updates the “Plan Start Date & Time” of the Work Unit(s) or Discrepancies or Maintenance Report(s) with the “Execution Date & Time” of the Technical Log.

• Dynamically calculates the “Plan End Date & Time” of the work units, based on the “Elapsed Time”. The system performs this validation only if (i) the “Action” drop-down list box in the “Planning Details” group box is left blank, and (ii) if the “Execution Date & Time” has got modified for any of the 'Technical Log' either in pop-up window or in the “Primary Work Center” field.

The system performs the following on clicking the “Plan Jobs” pushbutton:

1. Work Center Modification:

• If the work center # is modified in both, the pop-up window and in the “Primary Work Center” drop-down list box, then the system updates the execution document (Technical Log) with the work center number available in the “Planning Details” group box.

• If the work center # is not available in the pop-up window and in the “Primary Work Center” drop-down list box, then the system retains the existing work center # in the execution document.

• If the work center # is not available in the “Primary Work Center” drop-down list box, then the system updates the execution document with the work center # that is getting displayed in the pop-up window.

Note: The system performs the above mentioned validations, if the "Maintenance Report" or "Discrepancy''  associated to the technical log has source other than the current technical log, and also updates the 'Resolution History' page of the "Discrepancy" and/or  "Maintenance Report #'".

• Ensures that the Material Request(s) that are in “Authorized” status are short closed and the material issue documents that are in “Fresh” status are automatically cancelled.

• Automatic generation of new material request  takes place against the issue ware house of the new work center number, for part # - quantity - stock status combination of a shortclosed material request.

• Updates the execution station of the technical log with the execution station of the modified work center.

• If execution station is not mapped for the ‘Work Center #’ then system retains the existing ‘execution station’.

2. Modificaton of Execution Date & Time:

Modification of Execution Date & Time is allowed only for Technical Logs.

The system does not allow modification of the Execution Date & Time, if the modified date and time is:

• Later than the reported date and time of any of the discrepancies.

• Later than the compliance date & time of any of the work units, provided the work units are either (1) in ‘Completed’ or ‘Pre-Closed’ Status or (2) in “Incomplete” status with any of its subtasks “Signed-Off” / “Voided”.

• Later than any of the component replacements date and time.

• Later than the parameter updated date and time.

• Later than the fuel/oil uplift updated date and time.

• Earlier than the “Arrival Date & Time” of the last Leg # of the associated Journey Log #, If the current technical log is having the techlog basis as 'JL- Consolidated'.

Note: The above mentioned validation is applicable only if a Journey Log # is available, and is carried out considering the time zone of the Journey Log reported and time zone at which the Technical Log is been reported.

Note: Only one execution document must be selected, either “Visit Package” or Technical Log”

The system ensures that the selected work unit is not a “'Non Routine Item”, i.e. Unplanned Work Unit.

To “Un-Assign” the work units

•  Select “Un-Assign” from Action drop-down list box

•  Select an assigned work unit (A work unit which is assigned to any execution document, either “Technical Log” or “Visit Package”) from the “Planning Details Chart”.

•  Click the “Plan Jobs” push button to unassign the selected work units from the selected document

The work unit can be un-assigned only if the status is not 'In Progress' in the “Hangar Work Order” business component. When the work units get un-assigned from a visit package or technical log listed under the “Open Order” group box, the system moves the work units from the “Open Order” group box back to the “Work Unit Details” group box in the Gantt chart.

If any of the Work Unit(s) or Discrepancies or Maintenance Report(s) are getting un-assigned from a Technical Log #, the system will update (i) the “Plan Start Date & Time” of the Work Unit(s) or Discrepancies or Maintenance Report(s) with their respective “Schedule Date & Time”, and (ii) the “Plan End Date & Time” of the work units based on the “Estimated Elapsed Time” of the work unit.

Note: The work unit cannot be un-assigned, if the status of the work unit is “Pending” and if any “Material Request” is generated for the work unit.

To create “Technical Log” for the work units

•  Select “Create Technical Log” from Action drop-down list box.

• Select an un-assigned work unit (A work unit which is not assigned to any execution document, either “Technical Log” or “Visit Package”) from the “Planning Details Chart”.

• Click the “Plan Jobs” pushbutton to create a “Technical Log” for the selected work units.

Note: The system ensures that the "Numbering Type for Technical Log" drop-down list box is not left blank, in the “Set Options” activity of the current business component.

The work units that are associated to the technical log created here are moved from the “Work Unit Details” group box to the corresponding technical log number listed under the “Open Order” group box in the Gantt chart.

When the technical log is created, the system carries out the following:

• updates the “Plan Start Date & Time” of the associated Work Units or Discrepancies or Maintenance Report(s) with the “Execution Date & Time” of the respective technical log.

• Dynamically updates the “Plan End Date & Time” of the Work Units based on the “Elapsed Time” of the work unit.

To create “Visit Package” for the work units

• Select “Create Visit Package” from Action drop-down list box.

• Select an un-assigned work unit (A work unit which is not assigned to any execution document, either “Technical Log” or “Visit Package”) from the “Planning Details Chart”.

• Click the “Plan Jobs” push button to create a “Visit Package” for the selected work units.

When the visit package is created, the system moves all the work units that are associated to the visit package from the “Work Unit Details” group box. They are moved to the corresponding visit package number listed under the “Open Order” group box in the Gantt chart.

Note: The system ensures that the "Numbering Type for Visit Package" drop-down list box is not left blank, in the “Set Options” activity of the current business component.

To release “Visit Package” for the work units.

• Select “Release Visit Package” from the Action drop-down list box.

• Select a visit package from the “Planning Details Chart” for release.

• Click the “Plan Jobs” pushbutton to release the selected “Visit Package”

On releasing, the work orders are created as follows:

• One work order for one work center.

• One work order for one component removal.

• One work order for one standard procedure.

The system displays the following in the “Work Unit Details” multiline:

• Enter the following fields:

If the “Plan Start Time” is left blank, the system computes the same based on the following:

• If the “Work Center Loading Basis” drop-down list box is set as “Standard Work Calendar” in the “Set Options” activity of the current business component, the “Start Time” of the “Standard Work Calendar” is considered as the “Plan Start Time”.

• If the “Work Center Loading Basis” drop-down list box is set at any value other than “Standard Work Calendar”, the value 00.00.00 is considered as the “Plan Start Time”.

If the Plan End Date / Time fields are left blank, the system computes the same based on the following:

• If the “Work Center Loading Basis”  drop-down list box is set as "Standard Work Calendar" in the “Set Options” activity of the current business component, the system adds the “Estimated Elapsed Time” of the work unit with the “Plan Start Date” and  “Plan Start Time”.
