Hello!
Thanks for that update, and the new bit of information from the CVR

As stated, the after start check list looks like a "read and do" check list.
Not the best practice for standard routine actions, IMHO.
Who needs reading a book to accomplish simple actions such as setting the flaps? The check list should be called upon when the job is done by the crew member in charge, to check it was done! And this check is a two persons job ...
