The Range EC Effectivity button allows users to set up effectivity for aircraft using the A/C, A/C S/N, Line, Variable Number, SGML Designator or IPC.

From the Engineering Control window, select the Range EC Effectivity button.

The system displays the Engineering Control Range window.

Note: This window is affected by Switch ADDSTENGRANGE. When it is set to No, the windows Status and Reason fields, as well as the Copy Ranges button is not available.

Note: When Switch RANGEHELPER is set to Yes, the Individual A/C Selection button is available in the Engineering Control Range window which is used to set up effectivity for individual aircraft. For more information, refer to the Individual A/C Selection button via the Engineering Training Manual.

Type Drop Down

Select the Range Type from the drop down menu. This option allows the user to easily enter a range without having to override the E/C to the A/C S/N level. For example, this option is used when an AD states a specific range that the AD is effective to. The user does not have to override the A/C Type/Series to manually select/deselect the necessary A/C Tail Numbers.

A/C - Apply effectivity by Aircraft. This information is pulled from the A/C Master, General tab.

S/N (Serial Number) - Apply effectivity by specific Aircraft Serial Number. This information is pulled from the A/C Master, General tab.

Line - This information is pulled from the A/C Master, Optional 2 tab.

Variable No - This information is pulled from the A/C Master, Optional 2 tab.

SGML Designator - This information is pulled from the A/C Master, Optional 2 tab.

IPC - This information is pulled from the A/C Master, Optional 2 tab.
