__________________
 A. Test
 (1) Do the operational test of the LAND CAT III capability (Ref. AMM TASK 22-97-00-710-001).
 4. Fault Isolation
_______________
 A. If the test gives the maintenance message AFS: CHECK FAC2 RT:
 - do the Ground Scanning of the AFS (Ref. AMM TASK 22-91-00-710-001).
R (1) If the test gives a different message, do the trouble shooting R procedure related to the maintenance message. R
 (2) If the test does not gives the maintenance message, or if the fault continues:
 - do the operational test of the AFS (Ref. AMM TASK 22-96-00-710-001)
 and read the result for the FAC 2 and the FMGC 2. R
R (a) If the test gives a different message, do the trouble shooting R procedure related to the maintenance message.
 B. Do the test given in Para. 3.
