Cold and dark

[Jean tardiff]

Just starting to cold and dark and leaving from hangers . When I watch YouTube vids some people use ground power some just thevAPU . I would think most airlines would use ground power ?  Also the list seems to be missing some things that people use in the vids no counting fire tests

Hmm - I am not sure I understand the purpose of your post. Care to elaborate?

Cheers, Jan

Sorry about that, I was wondering what way do most people on here do cold and dark, is it with ground power or just APU, and just curious why the different videos show different orders to do things and some skip steps that other don’t . I printed of the work sheet to follow along but there are a few differences
