D. Start the engine and let it become stable at minimum idle for 2 minutes. (Ref. AMM TASK 71-00-00-710-003)

4. Procedure
Subtask 74-00-00-710-063-A ** ON A/C NOT FOR ALL

A. Do this Test:

ACTION	RESULT
1.on the MCDU:
Push the line key adjacent to PARAM LAB indication	The AIDS PARAM LABEL CALL-UP page comes into view
2.On the MCDU keyboard enter these parameters:
For engine 1: 07C/1/273/01/18 For engine 2: 07C/2/273/10/18	The parameters come into view under the RETURN indication.
3.Push the key 1L	The parameter shows in front of Key 1L
4.Pull circuit breakers 2KS1 (2KS2) and 4KS1 (4KS2) NOTE: Ignore the warning relatives to the EIU that can occur during the procedure that follows.	The engine speed increases from ground idle to flight idle On the ECAM display, make sure that IGN indication appears
5.Close circuit breakers 2KS1 (2KS2) and 4KS1 (4KS2)	The engine speed decreases from flight idle to ground idle On the MCDU , bit 23 of selected parameter is set to "0"
6.Push the line key adjacent to the RETURN indication	the AIDS menu comes into view
7.Push the line key adjacent to the RETURN indication until the MCDU menu comes into view.	MCDU MENU comes into view.

5. Close-up
