Hi Sergey,
Actually the only lights that are on on the overhead basically are the Apu, ON and Avail light, the Gen Fault Amber Lights and the Apu Bleed ON light if available as you saig the external power that in AVAIL or in ON... Remember the Airbus is a Dark cockpit configuration if no light means systems are working in AUTO if not normally you have lights for Systems OFF and Fault if something is not working... Also the Fuel Pumps if you are in the Gates they are in OFF!! Lighted white.
Take care,
Roberto
Thanks, Roberto!
When aircraft is in gate and powered by BAT 1/2:
1) - On overhead of Wilco A320 amber FAULT lights Hyd. ENG 1/2 PUMP, BLUE ELEC PUMP, green AVAIL and all Fuel PUMP's pb.'s OFF lights is on only;
- On overhead of PSS A320 amber FAULT lights GEN 1/2 , PACK 1/2, green AVAIL and all Fuel PUMP's pb.'s OFF lights is on only;
What is corrects?
2)Can I switch on Wing/Eng Anti Ice pb.'s or it can be switch on but start work only when first Engine start.
3)What External light I can switch on with bat only?
4) Can Static inverter supply AC power to feed BLUE/Yellow ELEC PUMP when aircraft is on bat ?

Hope it helps.

a) Then, how Hydraulic Yellow system hydraulicaly powered on the ground with Bat only ?Quote:

c) Can Yellow ELEC PUMP work in fly powered by AC from Emergence Generator when GEN 1/2 or (Eng 1/2). is fail??
d) Can I move the Trim, Rudder, Flaps, Ailerons/Elevators with Engines off ?
Dude,
a) You donīt operate any Hydraulic systems with the Batteries... Impossible the batteries are just to start the APU... Period... In an emergency electrical configuration when you only have batteries you deploy the Rat and that will drive you the emergency generator...
b)APU or Ext power Iīm telling you the batteries wonīt drive you anything...
c) Yes
d) No you cannot move them with the Engines off unless you pressurize in the maintenance panel the Hydraulics or you activate the Yellow Hydraulic pump that will enable hydraulics...
Regards,
Roberto
Thanks, Roberto for your answers !
Yes, but during RAT and emergency generator start work (aprr. 8 sec) or if RAT fail, the batteries through power invertor supply power to ACC ESS BUSS. Hence the aircraft don't loss AC power to supply it to Electric Hydraulic pumps and to other systems.Quote:

Is this correct?
The Yellow and Blue Hydraulic pumps can work only if I have the APU or EXT PWR on.
Is this correct?
Dude...
Yellow and Blue work Hydraulic pumps only work with the APU the External too on the ground of course... Now on Electrical Emergency configuration when you loose all generators you basically start flying the plane with rudder and trim and the batteries start supplying certain systems not sure about the Hydraulics I think not... Then the Rat deploys and you get the emergency generator or you start the APU so you get your hydraulics through the Electrical pumps, and the green from the yellow with the PTU.
Roberto
But if RAT and APU will not be started ? :(
How long time I can use accumulators for flying?
It doesnīt matter you are dead anyways..

Why when aircraft is powered by EXT PWR the amber FAULT lights is on on GEN 1/2 , PACK 1/2 Pb.s? Is it not inxibited on ground?
see: http://www.airliners.net/open.file/1176875/L/
Donīt confuse the Electrical generators with the Packs one thing has nothing to do with the other... The amber Fault light appears on ground on the generators with the Engines off that is the normal operation of the system... Same thing in all Airbus aircraft like the A-300, A-330 Etc... Pack 1 and 2 are in the auto lights off position. In that picture they are in FAULT cause there is no Air Bleed suplying the packs... The APU is off!

Roberto
Conclusion:
1. Aircraft is powered by BAT only
- EXT PWR pb. is "AVAIL" if external power is plugged
- FUEL PUMPS is "OFF" if in the Gate
-NO AMBER LIGHTS on overhead
2. Aircraft is powered by EXT PWR only (EXT PWR pb. is "ON")
- GEN 1 and GEN 2 pb.'s is "FAULT"
- PACK 1 and PACK 2 pb.'s is "FAULT"
- NO OTHER AMBER LIGHTS on overhead
3. Aircraft is powered by APU (APU MASTER SW and START pb.s is "ON")
- GEN 1 and GEN 2 pb.'s is "FAULT"
- PACK 1 and PACK 2 pb.'s is "FAULT" if APU BLEED pb. is in auto (extinguished),
if APU BLEED pb. is "ON" than NO PACK's "FAULT".
- NO OTHER AMBER LIGHTS on overhead
Please correct me.
I am the one confused now... LOL!
Dude really simple if the Bleed is ON which in that case is an ON/OFF Switch not an auto system... This is where you don't have to be confused... just cause there are no lights doesn't mean that the system is in auto... The APU Bleed is manual operation on and off basically if it is extinguished is in OFF.
The picture you sent me the Pumps are actually ON that is a normal panel configured before Start except that the APU is not ON cause they have the external to save GAS so you turn the APU on just before you start the engines...
The Gen lights will always be in Fault if the Engines are off PERIOD... Pack 1 and 2 are Fault in amber cause there is no Bleed air suplying them NO APU...

I think Serge either wants a battery for his birthday because he seems obsessed with batteries LOL or needs to actually take the Airbus course himself become a commercial pilot in an A320 and answer all his own questions LOL :)
Too funny Roberto especially DUDE!! The batteries dont drive **** LOL
