Hello everyone,
I apologize in advance if this has been discussed before but I couldn't find anything using the search function. Also, some of the discussions on that topic are quite old and I was concerned to read old references that may be out of date.
Throughout the Avionics smoke/smoke procedure, the crew has the option to set the emergency elec. config if desired.
I would like to know why the crew should: "APPLY ELEC EMER CONFIG PROCEDURE,
BUT DO NOT RESET GEN, EVEN IF REQUESTED BY ECAM." QRH 27.01C
I think there is an explanation in the FCTM that applies to that step but I don't get it.
"If at least one battery is charging when one side and then the other side of the electrical system are shed, the DC1, DC2, and BAT bus bars become inoperative for the remainder of the flight.
Therefore, the procedure for attempting to partially shed the electrical system was removed from the smoke procedure. This change in the procedure is to enable the flight crew to recover the normal electrical configuration for landing, particularly to recover normal braking. If the flight crew sets the electrical emergency configuration following a smoke detection in the avionic compartment ("AVIONICS SMOKE" ECAM caution triggered), the ECAM does not display the same procedure as the one displayed following the loss of main generators. In fact in this case, the ECAM displays a specific procedure that takes into account the smoke detection: As the flight crew has voluntarily set the electrical emergency configuration, the purpose of the ELEC EMER CONFIG ECAM procedure is not to try to restore the generators, but to remain in electrical emergency configuration, and restore generators before landing to perform the landing in normal electrical configuration."

Thanks in advance
