A. Test of the Wireless Ground Link-Digital AIDS Recorder (WGL-DAR)

ACTION	RESULT
1.In the E-Bay, on the WGL-DAR front panel:	In the E-Bay, on the WGL-DAR display:
Apply electrical power to the WGL-DAR. NOTE: After the WGL-DAR is energized, it does a self-test for almost 2 minutes.	The FAIL INDICATOR flashes. NOTE: After approximately 2 minutes, the FAIL INDICATOR light goes off and SYSTEM STATE comes into view.
2.In the cockpit, on the MCDU front panel:	In the cockpit, on the MCDU display:
Push the MCDU MENU button.	The MCDU MENU comes into view.
Push the line select key adjacent to the < AIDS indication.	The AIDS PARAMETER CALL UP page comes into view.
Push the line select key adjacent to the < DAR RECRDNG indication.	The AIDS:DAR RECORDING page comes into view. DAR = STOPPED comes into view.
Push the line select key adjacent to *MANUAL START indication. NOTE: It is not necessary to do the MANUAL WGL-DAR START procedure during this test if the WGL-DAR run control parameter is disabled. The modification of the WGL-DAR configuration file can change the WGL-DAR run control parameter.	DAR = RUNNING comes into view.
	In the E-Bay, on the WGL-DAR display:
	After some seconds RAWIN:SYNCIN comes into view. NOTE: The WGL-DAR NG synchronizes with A717 data stream in max 15 seconds.
In the cockpit, on the MCDU front panel:	In the cockpit, on the MCDU display:
Push the line select key adjacent to the *MANUAL STOP indication. NOTE: It is not necessary to do the MANUAL WGL-DAR STOP procedure during this test if the WGL-DAR run control parameter is disabled. The modification of the WGL-DAR configuration file can change the WGL-DAR run control parameter.	DAR = STOPPED comes into view.
	In the E-Bay, on the WGL-DAR display:
	After some seconds RAWSTP comes into view.
Push the line select key adjacent to the < RETURN indication until the MCDU MENU comes into view.	The MCDU MENU page comes into view.
3.In the E-Bay, on the WGL-DAR front panel:	In the E-Bay, on the WGL-DAR display:
Push the MODE button.	SYSTEM STATE comes into view.
Push the + button two times or until the ADVISORIES message comes into view.	ADVISORIES comes into view.
