A 7 knot direct tailwind is trivial.



I just checked a couple of my Cessna POHs.... for the 1981 172P and the
1980 Cutlass RG. In both in notes for takeoff or landing distances that
you should "increases the distance by 10% for each 2 knots of tailwind".

I don't consider 35% as trivial. Of course, that may only apply to those
two models of aircraft.

How much runway do you use? I use less than a 1000 feet when I'm hardly
trying, call it 800 feet. That's an extra 80 feet per 2 knots if all
you have to go by is the book.
