real life nuances
well done!
I don't know if you guys know about the book "fly the wing" by webb.
he speaks of a takeoff in supsected or possible windshear. he points out that finding out the max weight for takeoff from a particular runway and then using the "NUMBERS" (v1/rotate) for the highest weight allows you to have a reserve of speed at takeoff.
perhaps so too in suspected icing situation?
think about it, read his book, perhaps this is something that can prove the nuance concept expressed above...but in a numerical fashion.
