Interesting. In the EMER ELEC case (no dual flame out, just bus bars fault or whatever) I can't see in the INOPs if the L/G RETRACT is there or not, because it is "simplified". In the sys remaining it does not mention the retracting function, only the LGCIU 1 status (and that of the gravity system). So I guess the only way to know is to rule out the possibility of gear retraction due to the lack of some equipment, or by doing an experiment in the sim.
What I am more concerned with is with retracting the gear after a go around. In the case you are forced to divert, that is about 3 times the fuel required, which in most cases will mean you are in a fuel emergency.
