Hi, you're completely missing the point here.
Obviously I'm not talking about all the other stuff that needs to be done before starting like checklists, ground checks, closing doors, getting start/pushback clearance from atc (or the groundcrew getting it), etc...
The only thing I'm trying to make clear is that it would be wiser
not to use the word "pushback/push" or telling the ground crew that you're ready or cleared to do so until the parking brake is released. (After the groundcrew's permission to release them of course, as stated in my previous post.
)
I would hope this gets implemented in SOP's in those companies that don't do this yet. Usually SOPs only get changed after damage is done and lives are lost. THAT is a pity!
