Therefore the objective is to stay in Electrical Emergency Configuration until shortly before landing and then restore normal electrical configuration, to enable normal braking. This is why you do not reset the generators in this case.
Ok. Thanks for the reply.
1) Is it because after you apply the steps below, ECAM will tell you to reset
"GEN 1+2.....OFF THEN ON" ?
"TO SET ELEC EMER CONFIG
EMER ELEC GEN 1 LINE.......................................OFF
EMER ELEC PWR.......................................... MAN ON"
2) "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"
Can somebody expand on that statement?
3) Additionally, what change is the FCTM referring to? How was the procedure written before?
"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"
Thanks again.
