QRH Extract looks clear enough:
IF HYD NOT RECOVERED (line not displayed for
a double LO LVL):
A/THR......................................................... ..........OFF
Select the target speed on the FCU.
Due to the loss
of slats and some flight control surfaces, the A/THR
may not satisfactorily maintain speed.
FOR LDG............................................... USE FLAP 3
This line is replaced by “FOR LDG : USE FLAP 3
when CONF 3 is selected, as a reminder.
GPWS LDG FLAP 3..............................................ON
WHEN SPD 200 KT (displayed when slats are
retracted):
L/G.................................................GRVTY EXTN
Refer to PRO-ABN-32 L/G GRAVITY
EXTENSION
Extend the landing gear at 200 kt to revert
sooner in direct law. This provides, below 200 kt
, a better pitch control than in alternate law with
one elevator lost and all slats lost.
