I came across this old thread

Auxiliary Functions (continued)
Load Alleviation Function
The aim of the Load Alleviation Function (LAF) is to alleviate the fatigue and static loads on the wings by reduction of the wing bending moment.
The LAF is composed of:
- the passive turbulence alleviation and,
- the active turbulence alleviation.
The passive turbulence alleviation alleviates the static loads in turbulence and during maneuvers. The activation is based on the vertical load factor given by normal law. The computed orders are sent to the ailerons and spoilers 6 to 8.
The pitch compensation linked to the deflections is sent to the inner elevators.
The active turbulence alleviation alleviates the fatigue and static loads.
The activation is based on the measurement of the vertical load factor on the wings given by the accelerometer units installed on the pylons. The computed orders are superimposed (added) to the computed orders of the passive turbulence alleviation. They are sent to the ailerons. Compensation orders are sent to the inner elevators.
The LAF is activated above a given speed and, vertical acceleration thresholds but are inhibited when slats and flaps are in full configuration.
