Wheels \"spinning up\" before landing?
my dad and I were debating this last night...
Are the wheels on airliners "spun up" to speed before landing so there is not such a difference in the speed of the tire in relation to the runway? In other words, so the tire doesn't have to accelerate from 0 to 150 knots at the instant of touchdown.
He claims that they are, but I think that seems too expensive to do and the equipment would be too much of a weight penalty. So who's right?
