Airbus A320 AVNCS SMOKE

Hi there,
can't quite understand why is the EMER ELEC GEN 1 LINE pb so called ... is the 1 meant as "primary line" or "generator number 1" ? if intended as generator number 1, why is it necessary to isolate GEN 1 from AC1 line and powering AC1 through the BUS tie contactor (by GEN2) for AVNCS smoke procedures ? ... a bit confused !

Thanks in advance!

Don't have access to the FCOM right now, but as I remember it, the Gen 1 Line Pb isolates Gen 1 from the network apart from supplying the No 1 Fuel Pumps only in each tank.

The smoke procedure asks you, after you have taken certain measures but still have the smoke, to consider the Emerg Elec Config so you will end up taking both gennies off line, but with Gen 1 still supplying a fuel pump in each tank and the Emerg Gennie supplying the emergency network.

Hope that helps

Thanks for answering mcdhu, at this point I'm right to think EMER ELEC GEN 1 LIN pb has the purpose of powering one pump in each wing only ... otherwise it would have been possible to simply shut both the GEN while activating the EMER GEN ...

You've got it Fred!! I'm not aware of any other use for it - unless someone knows different!!
