## Discrepancy

(CAN) DURING A STABLE ILS APPROACH , AROUND 700 FT RA, THE AUTO-THROTTLE WENT IN RETARD MODE.  BEFORE IT HAPPENED ALL WAS FINE, ILS FREQUENCY WAS INSERTED VIA FMS WITH THE ILS IDENTIFIER IAW ADVISORY WIRE, DUE TO WIND, ALSO, VREF+10 WAS APPLIED ACCORDING AFM.  NO RELATED CAS MESSAGES POSTED.  WHEN PILOT REALIZED THAT THE SPEED WAS DROPPING FAST, HE ACTIVATED THE GO AROUND MODE TO HAND-FLOWN, THE ACFT RECOVERING THE G/S AND THE SPEED.  ACFT LANDED WITHOUT ANY DIFFICULTIES.
