You guys need to look up Part 25 aircraft certification.
You've dug yourselves into a hole if you want the world to believe that you can fly jets without having single engine performance that meets the departure and MAP profile.
And even if your not flying a Part 25 aircraft it's irresponsible to be flying twins with such reckless abandon.
If your gonna fly your twins like a single engine aircraft, you need to be flying single engine aircraft, well actually you shouldn't be flying at all...
