The system performs the following:

Calculating the part estimates

If you have chosen the “Simple Average” method, the system calculates the estimated quantity as the average quantities consumed for all the individual parts for each occurrence of the AP task or task in consideration, from the “Hangar Work Reporting”, “Component Work Reporting” and “Flight Log” business components.

If you have chosen the “Moving Average” method, the system calculates the estimated quantity as the average quantities consumed for all the individual parts for the recent occurrences that is specified in the “No. of Occurrences” field for the AP task or task in consideration, from the “Hangar Work Reporting”, “Component Work Reporting” and “Flight Log” business components.

Note: For calculating the averages, the system converts all the parts to their respective unit of measurement and rounds off the new estimated quantity to the nearest integer, if the “Fraction Not Allowed” option is selected in the “Create UOM” activity of the “Unit of Measurement Administration” business component. The system considers the parts, only when the estimated quantity is greater than zero.

Calculating the resource estimates

If you have chosen the “Simple Average” method, the system calculates the estimated time as the average time consumed for all the individual resources for each occurrence of the access panel task or task in consideration, from the “Hangar Work Reporting” business component.

If you have chosen the “Moving Average” method, the system calculates the estimated time as the average time consumed for all the individual resources for the recent occurrences that is specified in the “No. of Occurrences” field for the access panel task or task in consideration, from the “Hangar Work Reporting” business component.

Note: For calculating the averages, the system converts the resource estimated time to hours. The system considers the resource, only if the estimated time consumed is greater than zero in “Hangar Work Reporting/Component Work Reporting/Flight Log” business component.

Calculating the elapsed time estimates

If you have chosen the “Simple Average” method, the system calculates the elasped time as the average time consumed for each occurrence of the AP task or task in consideration, from “Hangar Work Reporting” , “Component Work Reporting” and “Flight Log” business components.

If you have chosen the “Moving Average” method, the system calculates the elasped time as the average time consumed for the recent occurrences that is specified in the “No. of Occurrences” field for the AP task or task in consideration from “Hangar Work Reporting”, “Component Work Reporting” and “Flight Log” business components.

The system updates the estimated elapsed time of all standard procedures

When “Delete Unused Parts / Resources” box is checked

Under the “Simple Average” method, if a part identified is not used for more than fifty percentage of the occurrences of the AP task or task in the “Hangar Work Reporting”, “Component Work Reporting” and “Flight Log” business components, the system sets the new estimated quantity of the part belonging to the task or access panel task to zero.

Under the “Moving Average” method, if a part identified is not used for number of recent occurrences specified in the “No. Of Occurrences” field for the AP task or task, the system sets the new estimated quantity of the part belonging to the task or AP task to zero.

Under the “Simple Average” method, if a resource identified is not used for more than fifty percentage of the occurrences of the AP task or task in the “Hangar Work Reporting”, “Component Work Reporting” and “Flight Log” business components, the system sets the new estimated time for the resource for the AP task or task to zero.

Under the “Moving Average” method, if a resource identified is not used for number of recent occurrences specified in the “No. Of Occurrences” field for the AP task or task, the system sets the new estimated time for the resource of the AP task or task to zero.

The part or resource details are permanently deleted for the AP task or task, only on clicking the “Edit Estimates” pushbutton.

When the “Add New Parts / Resource” box is checked

Under the “Simple Average” method, if a new part has been consumed for more than fifty percentage of the occurrences of the AP task or task in the “Hangar Work Reporting”, “Component Work Reporting” and “Flight Log” business components, and if the part is in “Active” status, the system temporarily adds the new part and the estimated quantity to the AP task or task.

Under the “Moving Average” method if a new part has been consumed for number of recent occurrences specified in the “No. Of Occurrences” field for the AP task or task in the “Hangar Work Reporting”, “Component Work Reporting” and “Flight Log” business components, and the part is in “Active” status, the system temporarily adds the new part and the estimated quantity to the AP task or task.

Under the “Simple Average” method, if a new resource has been consumed for more than fifty percentage of the occurrences of the AP task or task in the “Hangar Work Reporting”, “Component Work Reporting” and “Flight Log” business components, and the part is in “Active” status, the system temporarily adds the new resource and the estimated time to the AP task or task.

Under the “Moving Average” method, if a new resource has been consumed for number of recent occurrences specified in the “No. Of Occurrences” field for the AP task or task in the “Hangar Work Reporting”, “Component Work Reporting” and “Flight Log” business components, and the resource is in “Active” status, the system temporarily adds the new resource and the estimated time to the AP task or task.

Revise estimates – An overview

This page allows you to specify whether you wish to revise the estimated values for the parts, resource or the elapsed time, and also specify whether the estimates must be revised for the task or access panel task.

You can select the method in which the estimated values must be calculated. If the “Simple Average” method is selected, then the system considers all the occurrences of the task or the access panel task in the “Hangar Work Reporting”, “Component Work Reporting” and “Flight Log” business components, for calculating the revised value. If the “Moving Average” is selected, you must enter the number of recent occurrences of the access panel task or task that must be considered for calculating the revised value.

You are also provided with the option of deleting parts or resources that are not used during the execution of the task or access panel task. You can add new spare parts or resources that are used for executing the access panel task or task.

You can search for the task or access panel task for which the estimated values have to be calculated. For access panel tasks, you can carry out the search based on the access panel task number or its type. For tasks, you can carry out a search based on the task number, revision number, task category, type or task applicability.

The system calculates the estimated values and stores the values temporarily for the task or access panel task. You can update the estimated values permanently for the tasks or the AP tasks in bulk, or select a particular task or AP task to be updated. On updating, the estimated values are updated, depending upon the work unit type selected.

You can also select a particular task and modify the calculated estimated quantity for the part in the “Revise Part Estimates” page. The “Revised Resource Estimates” page allows you to modify the calculated estimated time for the resource. The calculated estimated elapsed time details can be modified in the “Revise Elapsed Time Estimates” page.
