ALERT HEIGHTAH is the height above the runway, based on the characteristics of the airplane and its fail operational system, above which, for a CAT III approach a go around must be initiated if a failure occurs in one of the redundant parts of the automatic landing system, or in the relevant ground equipment - AUTOLAND light triggered.For A320 the Alert Height is 100 ft RA
DECISION HEIGHTDH is the wheel height above the runway elevation by which a go-around must be initiated unless adequate visual reference has been established and the aircraft position and approach path have been assessed as satisfactory to continue the approach and land in safety.

not indicated - no FMA downgrading.
