@boeingchiefpilot, please change your FCOM.

PS: the "major airline" reasoning... Major airlines have one downside and that is that people spend way too much time in one ecosystem and start to believe it is the one and only truth. It's not because you are a "major" airline, you are "a better reference" (AA587 is a fine example), otherwise all major airlines would have the same procedures. Unfortunately they differ quite a lot.

It's not a bad idea to go back to the basics where it all is supposed to start: the Boeing original FCOM (ALL major airlines procedures are based on this reference, so you should ask Boeing why the procedure was written that way in the first place, before claiming it to be completely "unnecessary").

AA 587 had nothing to do with required call outs


Some operators choose to follow Boeing procedures word for word, that’s an ecosystem of its own


However Airlines are free to customize Boeing procedures as they see fit and do so all over the world, once the relevant aviation authority approves them they become SOP


Our procedures worked very well for us, more talking doesn’t mean a better way of doing things
