Storm in a teacup.
In my humble 15 years of multi-crew flying, not once have I heard a discouraging word when someone wanted to practice "hand-flying".
If anything, I have witnessed the total opposite.
"Nah mate, I don't build FMC circuits, I just turn all that
off and fly it like a man."
When I hear those words, I sit up in my seat and review unusual attitude recovery in my mind! Have witnessed plenty of white knuckled, shiny lever, wrestling matches and usually at the end of a big day!
Why make it tough?
