[Edit: I am wrong. Ignore this]

>"Runways generally point in the wind direction, as aircraft take off and land more easily upwind. The designation of these is based on their respective alignment angles."

NO!!

This is exactly 180º wrong -- what generates lift on a wing is _relative_ airflow and thus pilots preferentially prefer to take off or land into a headwind -- which mimics speed "for free".

Likewise, tailwind landings are downright dangerous for the same reason, and each aircraft has strict (and low) limits for the maximum permitted tailwind. The illustration is exactly the other way around.




"Upwind" means "into the wind", right? This seems to be written correctly to me.


I'm an idiot -- you're right. Apologies. The graphic vectors looked like the wind was blowing the wrong direction and I missed this.


Haha no problem, you're not an idiot! You still explained why this is relevant to pilots, which is helpful to know.


Yes, just like downstream and upstream for rivers.
