A320...APU inop Vs Parking Procedure (Engine Shutdown)
Hello...
it happend to me some times that we dispatch without APU.
my question is...
when you stop at the gate,what is the proper sequence of shutting down the engines.
the procedure i have seen it with most pilots : they shut down engine no.1 and then wait to connect EXT PWR then shut down no.2 .
but this is not written any where...(at least i didn't read it any where)
but my thought is...if you shut down no.1 first you will lose the green hydraulic system pressure...so you don'y have the normal braking system.
you will still have the alternate braking but you have to select NWS switch off...in case you need it.
actually it happened to me couple of days ago...we shut down no.1 then we had to wait 10 mins till they brought a good ext pwr unit.and i was looking at the ECAM hyd page...and the green system px was down...
thanks
