Non functioning APU on A380 [in SIN]
Last nights LH779 operated by DAI-MF ‘Zurich’ , A380, the APU was not working & apparently it left FRA the night before in the same condition. Upon boarding it was hotter than Hell, and we had to wait for 50 minutes until pushback & the engines were started to get any relief, it was bad in F but apparently in Y & J much worse with some pax in distress. Very poor management to board pax so early given the circumstances ! The Pilot then had the nerve to blame Changi airport that their supplied air conditioning was not good.... since when were they responsible for LH maintenance failings..... Not LH’s finest hour ! |
APU is obviously MELable on LH (which doesn’t surprise me) choose your poison- both flights severely delayed and/or cancelled, or climate control issues at boarding |
I guess Herr Kapitän meant that those a/c tubes they connect to the aircraft weren't very good which is quite a curious thing in an airport like SIN. I'd imagine you wouldn't want to sit on stand and use an APU if you can avoid it- it burns fuel and we know how much Helga is committed to the climate emergency.

Yeah, I suppose pax onboard would be a lot more angry if the flight was cancelled due to the cabin being to hot!
I'm sure you all survived and tomorrow it will be forgotten. |

Oh, yes he was blaming it all on those tubes at SIN, presumably APU is always required on an A380, that the aircraft left FRA without it functioning is poor & 8 hrs on the ground they either couldn’t fix it or LH didn’t want to pay for the repair bill at Changi... If there's no fed A/C then they use the GPU also right which feeds the onboard A/ C power? I mean, in Europe thats mostly what you see? Or is that only working on SH aircraft because the GPU can't supply enough leccy? |
Also most airports don't allow you to run the APU while parked. My guess is that all widebodies in SIN are hooked up to the terminal/jetway aircon while at the gate... if the APU was already inop while leaving FRA Changi should/would have provided a GPU at the stand?
See page 35 onwards in the SIN GOSM: https://www.changiairport.com/conten...f-use/GOSM.pdf |
APU is rarely used for air conditioning on stand and often only powered up shortly before push-back to bridge the power gap until engines are started. It's not a critical item that is required and aircraft can fly without it

Don't worry. Her latest SIN sale will mean her coffers are full for any future issues!

Depends on the aircraft type (two- or four-holer) and route (i.e. max distance from nearest alternative).
all in all I don’t think this is something to get excited about i’m willing to guess the 50 minute ground delay was a slot restriction thing which is also not really LHs fault sully wouldnt have had problems with a double engine failure if he had 4 engines so i’m not sure the fact he used the apu is really relevant to the discussion here |
