Listen to the wise words of pterodactyl, you do not get to be as old and wise as a pterodactyl without knowing a thing or two.
411A you may be surprised to learn that notwithstanding that I wholeheartedly agree with you about the C441 being an outstanding aircraft, it's actual EFATO performance at gross weights isn't all that much better if at all, than the C404, neither is it required to be. "measurably positve" is the go. It's the old FAR23 certification issue. There are no legal EFATO figures (beyond accelerate/stop/go distances 50 ft obstacle) for FAR 25 type climb gradient other than for Engine inop ROC. If you take the time it is possible to construct a defacto FAR25, 1 thru 4 climb segment obstacle clearance scenario, but it is not provided.
Like the C404 or any FAR 23 twin including the B200/MU2/Cheyenne. blah blah, especially the big MU2s and don't get me started on those, in the EFATO scenario you are just hanging out there damned if you do and damned if you don't.
