5 Make sure that the difference between the NWS ANGLE 3GC SYS 1
_ (value A) and NWS ANGLE 3GC SYS2 (value B) is less than or equal to 0.8 degrees.
(c) If any of the above parameters is out of tolerances, do the applicable steps:
1 If the CAPT ANGLE value is more than 0 deg. plus or minus 0.4
_ deg. for the SYS 1 and/or SYS 2:

- On the STEERING DATA page of the BSCU SYS 2, push the line key adjacent to the REFRESH indication.
- Record the value of the pedal angle (value B2).
- on the MCDU, push the line key adjacent to the RETURN indication to get the SYSTEM REPORT/TEST/L/G page.
- If the values A1 and/or A2 only are more than 0 deg. plus or minus 0.1 deg.: . Replace the ELAC-1 (2CE1) (Ref. AMM TASK 27-93-34-000-001) and (Ref. AMM TASK 27-93-34-400-001).
- If the values B1 and/or B2 only are more than 0 deg. plus or minus 0.1 deg. : . Replace the ELAC-2 (2CE2) (Ref. AMM TASK 27-93-34-000-001) and (Ref. AMM TASK 27-93-34-400-001)
