Hello,
The Flight Controls Check on the A320/319/321 variants can be carried out at a convenient time as per the SOP — either while taxiing or after engine start. The main purpose of this check is to ensure that the ELACs and SECs are functioning correctly, the sidestick is electrically connected, and that pilot control comfort is satisfactory.According to Airbus procedures, if the check is performed while taxiing, it should be done while taxiing in a straight line, with one pilot always looking outside and the other performing the check.
Based on my experience, once at VOHS (Hyderabad, India), after completing the Flight Controls Check, an ELAC 1 Fault was displayed. The same fault reappeared when the check was repeated.
Performing the Flight Controls Check is an important part of ensuring the aircraft’s airworthiness before flight.
