Unfortunately, in the case I know about, both ELAC pitch channels failed during the roll during a touch-&-go.
Obviously, the ECAM warning was inhibited due to the present flight phase. Even worse, with this failure, and with the gear down, the aircraft was in DIRECT LAW, also unannounced by ECAM due to flight pass inhibition.
The PF was a bit surprised by the "strange" handling during the take-off (it's not every day that the Airbus is flown in Direct law
).
The first time that there was indication that something wasn't working was when the aircraft passed 1500ft AGL, and the ECAMs ELAC 1 PITCH FAULT and ELAC 2 PITCH FAULT were announced.
Since the landing gear had been retracted, the aircraft was now in ALTERNATE LAW, and the associated ECAM warning was displayed. Resetting the ELACs returned the systems to normal operations.
