Range:To	The maximum number in the range of values for a range parameter (Decimal) Data entry in this field is mandatory if the parameter is of “Range” type. Leave this field blank if the parameter is of type “Consumption”.
Average Daily Utilization	The average daily utilization for a consumption parameter based on which the forecast factor is calculated (Decimal). Data entry in this field is mandatory if the forecast factor and the formula-ID are not specified. Leave this field blank if a value is entered in the “Forecast Factor” field.
Forecast Factor	The multiplication factor to forecast the maintenance activity (Decimal). Ensure that the forecast factor is specified only for a consumption parameter. Data entry in this field is mandatory if the average daily utilization and the formula ID are not specified. Leave this field blank if a value is entered in the “Average Daily Utilization” field. This field must be left blank if the “Lead Parameter” field is left blank in the previous page.
Ultimate Life Value	Enter the value identifying the life of the component if you have set the consumption parameter as the life parameter (Decimal). Data entry in this field is mandatory if the consumption parameter has been chosen as the life parameter.

The system displays the following field on clicking the “Edit Parameters” pushbutton:

Rem. Life

The remaining life of the component, which will be calculated based on the ultimate life of the component. The value is calculated as the difference between the value specified in the “Ultimate Life” field and the “Present Value” field.

Enter the following field:

Formula #

The formula to be associated with the consumption parameter (Alphanumeric, 20). Mandatory. Ensure that a value is entered in this field if the “Parameter Source” is selected as “Calculated. The value of the consumption parameter is updated based on the formula entered in this field.

Ensure that the formula is already defined in the “Formula builder” business component. Data entry in this field is mandatory if you have not specified the average daily utilization and the forecast factor.

Help facility available.

Note: You can specify only one of the following values for a consumption parameter: the average daily utilization, forecast factor or the formula ID.

The system displays the following fields on clicking the “Edit Parameters” pushbutton:

Formula Content	The contents of the formula entered in the “Formula ID” field.
Parameter Description	The textual description of the parameter.

	Delta – Select this option to indicate that the new parameter value is added with the existing parameter value.
	New – Select this option to indicate that the parameter value is overwritten by the new parameter value.
	The system sets the field to “Delta” by default.

Note: Ensure that atleast one consumption or range parameter is entered in the multiline.

Note: On clicking the “Edit Parameters” pushbutton, the system updates the value “New” in this field for the parameter of type “Range”, even if “Delta” option is selected.

Check the box in the “Select” column of the multiline to mark the parameters for deletion.
Click the Delete icon in the tool bar above the multiline, to delete the parameters selected in the multiline.
Click the “Edit Parameters” pushbutton to update the consumption and range parameters for the component.
The system attaches the parameters to the component only for those rows that are not marked for deletion and updates the details of the parameters that have been modified. It also fills in the “UOM”, “Parameter Type”, “Formula Content” and “Parameter Description” fields. The system attaches the parameters that are defined for the component family to the component, on cli1cking the “Edit Parameters” pushbutton.
The system does not allow you to define formula for the calculated parameter, on either of the following conditions:

If the formula contains a combination of Base Parameter and Summary Parameter, and if the Base parameter and Summary Parameter exist in current Model Consumption and range parameter.
If the formula contains a combination of Summary Parameter and Leg Level Parameter, and if the Summary Parameter and Leg level Parameter exist in current Model Consumption and range parameter.

Note:

Base Parameter is defined in the “Set Base Parameters” activity.
Summary Parameter is defined as a Parameter with Source Type set as “Flight Log”.
Leg Level Parameter is defined in “Maintain Flight Log Parameters” activity.

The system does not allow you to map the Parameter with Source Type as “Flight Log” as the following Base parameters: ‘Flight Hours’, ‘Flight Cycles’, ‘Block Hours’, ‘Flight Days’, ‘Landing Cycles’, ‘Engine Hours’, ‘Engine Cycles’, ‘Hobbs Meter Reading’.

To proceed, carry out the following

Defining consumption and range parameters for the component – An overview

The consumption and range parameters defined for the part are displayed, and you can add new parameters to the component by entering the parameter details in the multiline. You can also select a parameter using the help facility. The parameter source must be specified for the parameters that are attached, to indicate the source from which the value of the parameter can be updated.

You can specify the maximum and minimum range value for range parameters. For the range parameters that are already attached to the component, you can modify the parameter source, which indicates the source from which the value of the parameter can be updated, and the maximum and the minimum range values.

For consumption parameters, you can specify the average daily utilization or the forecast factor or the formula ID for forecasting the next maintenance activity on the component. You can also set the consumption parameter as a life parameter that indicates the life of the component. If the consumption parameter is set as the life parameter, you must define the ultimate life, based on which the remaining life of the component can be calculated. For the consumption parameters that are already attached to the component, the parameter source, average daily utilization, forecast factor, formula ID and the ultimate life, if the parameter has been identified as the life parameter, can be modified. Whether the warranty tracking is applicable for the parameter, whether the parameter has to be updated using some range values or constant values, and whether the parameter update is mandatory each time when the parameter values changes, can also be modified.
