A320 stability question

Hi guys,

quick one:

flying the ils with a 320. Hands off the stick. We get a heavy wake and one wing rises.

will the Airbus start turning or come back to the previous attitude and compensates the wake?

thanks!

WAKE TURBULENCE RECOVERY:

If the aircraft encounters wake turbulence, pilot input can amplify the effect of the vortices. All of

the following is therefore recommended:

‐ Do not use the rudder: Use of the rudder does not reduce the severity of the encounter, nor

does it enhance the ease of recovery.

‐ Keep the AP ON: The AP is able to correctly manage roll and pitch movements that are

generated by wake turbulence. However, if the aircraft encounters severe wake turbulence, the

AP may disconnect.

‐ If the AP was set to OFF by the flight crew or automatically disconnected, release the controls

and wait for a reasonable stabilization of the aircraft.

When the aircraft is stabilized perform both of the following:

‐ Roll wings level

‐ Establish again the trajectory.

As the wing is going up, the FCCs are working to reduce the roll rate to zero. The bank will remain where it is when the roll rate reaches zero.

Basically the FCCs reject any changes in pitch and roll that do not come from the side stick. They may succeed fully or partly. If they succeed partly then pilot will have to complete the remaining action.
