The alarm (one engine in Thrust reverser X the other above idle) was created by Airbus after the TransAsia Airways in Taiwan.
Could(Should) it be inserted in planes made prior to the FWC standard H2F3 (this one being the first in which the alarm was implemented in) ?
This is done by upgrading the FWC software or the FWC itself - don't have the knowledge to say which - but it can be done on any A320.. the investigation will tell us whether the ECAM warning occurred.
