This page allows you to add or modify the consumption and range parameters for the selected aircraft. Tell me more.

Select the “Edit Consumption & Range Parameters” in the main page.

The “Edit Consumption & Range Parameters” page appears.

The system displays the following field:

Date & Time Format

The format in which the date and time fields appears in this page. This format is displayed from the "User Preferences" business component based on the login user ID. In case the format is not defined, the system displays the date and time format from the “Enterprise Modeling” business component by default.

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

Aircraft Reg #	The registration number of the selected aircraft for which you wish to define the parameters.
Manufacturer Serial #	The MSN or the manufacturer’s serial number given to the aircraft by the manufacturer at the time of production.

Note: On launching the page, the system displays all the consumption and range parameters that are already associated for the aircraft else displays the consumption and range parameters defined for the aircraft model, to which the selected aircraft belongs, in the “Parameter Details” multiline.

Enter the following field in the “Parameters Details”, if you wish to define new parameters for the aircraft:

Parameter

The identifier of the parameter (Alphanumeric, 40). Ensure that the parameter is already defined in the “Create Parameters” activity and is of type “Consumption” or “Range”. You must enter the “Consumption” type parameter if the “Formula #” field is entered.

If the "Parameter Source" of the parameter is specified as 'Parent', then the parameter must be defined in the "Identify Inheritable Parameters" activity.

Help facility available.

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

UOM	The unit of measurement of the parameter.
Parameter Type	The type of the parameter, which can be “Consumption” or “Range”.

Enter the following fields:

Life Parameter	Use the drop-down list box and set the field to “Yes”, to set the parameter as the life parameter. The life parameter is the consumption parameter that indicates the life of the equipment. Select “No” if you do not wish to set the parameter as a life parameter.
Parameter Source	Use the drop-down list box to select the parameter source from which the value of the parameter has to be updated. The system provides the options “Flight Log”, “Manual",and “Calculated”
	Flight Log - indicates that the parameter value has to be updated from the flight log. You cannot select this option for parameters “Flight Hours" (FH), "Flight Cycles" (FC), "Block Hours" (BH) and "Landing Cycles" (LC) of the aircraft.
	Manual - indicates that the parameter value has to be updated manually.
	Computed - indicates that the parameter value is updated based on the formula associated to the parameter. This formula depicts the mathematical relationship of the parameter with the participating parameters. When one or all the participating parameters are updated, the formula based parameter will be automatically updated. You cannot select this option for parameters “Flight Hours" (FH), "Flight Cycles" (FC), "Block Hours" (BH) and "Landing Cycles" (LC) of the aircraft.

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

Present Value	The present value of the parameter.
As Of Date	The date on which the present value of the parameter was recorded.
As Of Time	The time at which the present value of the parameter was recorded.

Enter the following fields:

Range: From	The minimum number in the range of values for a range parameter (Decimal). Mandatory.
Range:To	The maximum number in the range of values for a range parameter (Decimal). Mandatory.
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.
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.
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 aircraft is calculated by the system based on the ultimate life specified for the life parameter.

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 fills in the following fields on clicking the “Edit Parameters” pushbutton:

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

Enter the following fields:

Warranty Tracking	Use the drop-down list box to indicate whether the warranty tracking for the parameter is “Applicable” or “Not Applicable”.
Parameter Update	Use the drop-down list to Indicate whether parameter updation is “Mandatory” or “Non-Mandatory” each time when the parameter is edited for the aircraft.
Update Mode	Use the drop-down list box to select the mode on which the parameter value has to be edited. The system lists the following options:
	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: 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.

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 parameter details for the aircraft.

Note: The system attaches the parameters to the aircraft only for those multiline rows that are not marked for deletion.

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

Select "Initialize Parameter Values" link at the bottom of the page to initialize parameter values for an aircraft that is in "Under Creation" status.

Defining consumption and range parameters for the aircraft – An overview

The aircraft inherits the consumption and range parameters defined for the aircraft model. You can add new parameters to the aircraft by entering the parameter details in the multiline. The parameter source must be specified, 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 aircraft, 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 aircraft. You can also set the consumption parameter as a life parameter that indicates the life of the aircraft. If the consumption parameter is set as the life parameter, you must define the ultimate life, based on which the remaining life of the aircraft can be calculated. For the consumption parameters that are already attached to the aircraft, the parameter source, parameter average daily utilization, forecast factor, formula id and the ultimate life, if the parameter has been identified as the life parameter, can be modified.
