You kidding right?

At cruise levels you routinely see winds of 50, 100, or more knots.
Cruise at 450 kts and factor a head wind of 100 kts and you'll see it
makes a big difference on range.

For t/o winds and temperature are always taken into account, again can
make a big difference on load you can carry.

no I'm not kidding. I'm referring to Pilatus PC9's in training roles.
