This page allows you to enter the date-based schedules for the position code and the part number. Tell me more.

Select the “Edit Date Based Schedules” link at the bottom of the “Select Position – Part #” page.

The “Edit Date Based Schedule Information” page appears.

The system displays the following in the “Position Details” group box:

Aircraft Model #	The number identifying the aircraft model with which the position code is associated.

Work unit #	Use the drop-down list box to select the work unit for which the date-based schedule must be specified. The system lists all the work units (except those for which ‘Shelf Life Expiry’ flag is set to “Yes”) that have been defined for the part program and prefixes it with “TSK”, “SP” or “WP” based on the type of the work unit.
Note: The system will not display those work units for which the “Shelf life expiry” flag has been set to “Yes” in the “Edit Part Program Information” page.
Get Part Program	Check the box to get the part maintenance program for the part selected.

Click the “Get Details” pushbutton to retrieve the date-based schedule details that are already defined for the work unit.

The system displays the following on clicking the “Get Details” pushbutton:

Work Unit Description	The textual description of the task, standard procedure or work package.
Maintenance Type	The type of the maintenance activity to be carried out.
Work Center #	The number identifying the work center where the work unit is performed.
Work Center Description	The textual description of the work center.

Enter the following in the “Date Based Schedule Details” multiline:

Schedule Type	Use the drop-down list box to specify whether the work unit has to be performed on the “Recurring” or the “One-Time” schedule type. Mandatory.
Time Unit	Use the drop-down list box to specify the unit of measurement of time. The system lists the options “Days”, “Weeks”, “Months”, "Month End" and Years”. Mandatory.
Threshold	The starting value for performing the particular work unit (Decimal). Data entry in this field is mandatory if the “Schedule Type” is set as “One-Time”. Ensure that the number entered in this field is positive.
Interval	The interval in which the work unit is to be repeated (Decimal). Data entry in this field is mandatory if the “Schedule Type” is set as “Recurring”. Ensure that the number entered in this field is positive. This field should be left blank, if the “Maintenance Type” for the maintenance activity is set as “Retire”.
Alert Value	The value before the actual arising when an alert needs to be given on the impending work unit execution (Decimal). Ensure that the number entered in this field is positive
Positive Tolerance	The upper limit within which the work unit has to be performed (Decimal). Ensure that the number entered in this field is positive.
Negative Tolerance	The lower limit within which the work unit has to be performed (Decimal). Ensure that the number entered in this field is positive.

Recording date-based schedule details for position code – An overview

This page allows you to enter the date-based schedules for the position code and the part number selected in the main page. You can select the work unit that is associated with the maintenance program of the part selected in the main page and specify the schedule details. Date-based schedules have their periodicity defined in terms of calendar days. The schedule for the next performance of the maintenance activity will be specified in terms of a calendar date.

Date-based schedules are employed for maintenance activities, which are to be performed irrespective of the asset usage. If the asset has a constant usage pattern then the activities based on usage can be translated to date-based schedules. Routine maintenance based on date schedules has a higher degree of predictability, which inherently increases planning efficiency.

The date-based schedule can be of two types: “Recurring” and “One-Time”. In case of “Recurring”, the next due date is calculated from the date of execution of the previous schedule. In case of “One-Time” you can specify the maximum number of days, weeks, months or years within which the work unit has to be executed.

Alert value or date specifies the value or date after which the corresponding work unit is considered in the component maintenance forecast. You can also specify the positive and negative tolerance, which indicate the limits within which the work units are to be performed.

The system updates the date-based schedule details and stores the name of the currently logged in user and the current server date.

Note: If the status of the schedule for the position code is “Authorized”, the system changes the status to “Fresh” on updating the date-based schedule details .

What you can do in this page

Indicate the schedule type

The date-based schedule can be of two types: “Recurring” and “One-Time”. In case of “One-Time”, the work unit will be performed on a particular date. In case of “Actual Interval”, the work unit will be performed in repeated intervals.

Set the “Schedule Type” field as “Recurring” to indicate that the work unit is to be performed in repeated intervals.
Set the “Schedule Type” field as “One-Time” to indicate that the work unit is to be performed on a specified date.
