This page allows you to create a formula.
Select the “Create Formula” link under the “Formula Builder” business component.
The “Create Formula” page appears.
Note: Upon launching this page, the system lists the consumption and range parameters (defined in the “Aircraft” business component) that are in “Active” status, in the multiline.
Enter the following fields in the “Formula Details” group box:
|
Formula # |
The unique identifier for the formula to be defined (Alphanumeric, 15). Mandatory. |
|
Formula Description |
The textual description of the formula (Alphanumeric, 80). Zoom facility available |
|
Formula Content |
The actual formula (Alphanumeric, 150). Mandatory. Zoom facility available. |
Follow these rules while creating a formula:
Only consumption and range parameters created in the “Aircraft” business component that are in “Active” status can participate in a formula.
The numeric values such as positive, negative integers and decimals can take part in a formula.
The operators +, -, *, / are allowed, and a valid operator should be present between two parameters or between a parameter and a numeric factor.
An operator should have a parameter or a numeric value before and after.
Operators should always be seperated by either numeric factors or parameter codes. P1/(P2+P3) is a valid formula, whereas P1//(P2+P3) is invalid.
Parentheses are allowed in a formula and they should be paired.
The factors specified in the formula must be numeric. Example: 2.1*(P1+P2) is a valid formula, whereas a*(P1+P2) is invalid.
The system lists the consumption and range parameters (defined in the “Aircraft” business component) that are in “Active” status, in the “Parameter Details” multiline.
The system displays the following fields:
|
Parameter |
The consumption or range parameter as defined in the “Aircraft” business component. |
|
Parameter Description |
The textual description of the consumption or range parameter. |
Check the box in the "Select" column of the multiline to select the parameter.
Click the “Transfer Parameter” pushbutton to transfer the parameter selected in the multiline to the “Formula Content” field in the “Formula Details” group box.
Provide a valid mathematical operator in the “Formula Content” field in the “Formula Details” group box.
Enter a valid numeric factor in the “Formula Content” field or select another parameter in the multiline and transfer the parameter to the “Formula Content” field.
Click the “Create Formula” pushbutton to create the formula.
Note: The system creates the formula and sets the status of the formula to “Active”. Whenever the participating parameter values are updated, the formula builder computes the value of the dependent parameter as per the relationship defined and returns the computed value as the output value.
