the.com/crosswind
the wind that turns a runway into a dare and pilots into tightrope walkers
means A wind blowing across your direction of travel rather than head-on or behind you, pushing you sideways and forcing constant correction.
from A plain English compound, bolting "cross" (from Latin "crux," a cross or crossing — the sense of one line cutting athwart another) onto the very old Germanic "wind." The aviation flavor is modern, but sailors knew crosswinds long before runways existed, and the word simply describes geometry: a wind set crossways to your heading.
- crab angle
- planes land pointed sideways, then snap straight
- limits
- every aircraft has a max crosswind it won't exceed
- gusts
- sudden sideways shoves are deadlier than steady wind
- diversions
- strong enough, it sends jets to other cities
for instance
wellington airport new zealand — strongest crosswind runway in world at 20 knots, high altitude location creates extreme conditions
