On my way to work, I drive by the aiport, and I have noticed that on some mornings (when the weather is calm/nice) the planes land and takeoff in different directions...
For instance, I saw a plane land on rw 18, and right after, a plane took off from rw 36 (heading for a destination north), and right after another plane landed on rw 18, all this during a 5-10 min time period.
Why does the direction of landing and takeoff change like this?
Is it, since the weather was calm, they planes can takeoff/land in a direction that is beneficial to their origin/destination?
