October 26, 20187 yr I was just wondering if I'm doing something wrong, if this is a bug or this is normal for the 747-8f... Every time I start the power of the 747-8f (I don't really fly the pax version) I get a PACK sys fault on the PACK RST button. I have done the shutdown, secure and Elec power down exactly as is described in the FCOM. everything is normal on power down but on power up as soon as I switch on the EXT POWER or APU GENs and the systems come on the TRIM AIR valves stay closed and I get a sys fault on the PACK RST. Is this normal for the 747-8 or is this a bug?
October 26, 20187 yr Sven, I assume you have all three packs off when you secure the aircraft. Then when applying power you get a PACK RST light with packs off? I have seen this happen once or twice, and after resetting the pack controllers all worked as expected. If you are seeing this often then I would suspect the panel file. If it were a bug it would be a common complaint in the forum and your post is the first I've seen on this topic since the -8 was released. Dan Downs KCRP

Funny thing is I did a full Windows re-install a week ago (I do it once a year) and after that the same thing happens. I also made a new start-up file after following the FCOM to the letter and it still happens. But yeah as you say pressing the PACK RST button switches the TRIM AIR valves back on so it's not a big deal, I was just curious.

November 10, 20187 yr Author I've pinned it down. As soon as I cut the GEN power the Trim air valves lock up or something. Doesn't matter if it's on apu power or ground power or with the packs on or off. I think it's just a bug.
