A. At the end of the flight, do a check of the residual ground speed:
(1) On the CAPT ND:
- to read the residual ground speed related to the IR3: . set the ATT HDG selector switch to CAPT/3.
(2) On the ADIRS CDU:
- set the DATA DISPLAY selector switch to TK/GS
- set the SYS DISPLAY selector switch to 1 (IR1) or 3 (IR3)
- read the related ground speed in the CDU display.
NOTE : The radial position error does not stay in the memory of the
____ MCDU after the aircraft electrical circuits are de-energized.
4. Fault Isolation
_______________
A. Compare the ground speed values that you read with these limits:
(1) If the residual ground speed value is lower than or equal to 14 kts, no maintenance action is necessary.
(2) If the residual ground speed value is equal to or greater than 21 R kts, replace the ADIRU1 or ADIRU3 (Ref. AMM TASK 34-12-34-000-001) R and (Ref. AMM TASK 34-12-34-400-001).
(3) If the residual ground speed is between 15 and 20 kts, you must do a check of this value after the subsequent flight:
(a) If after the second check, the residual ground speed is lower than or equal to 14 kts, no maintenance action is necessary.

(b) If after the second check, the residual ground speed is 15 kts or R more, replace the ADIRU1 or ADIRU3 (Ref. AMM TASK 34-12-34-000-R 001) and (Ref. AMM TASK 34-12-34-400-001).
