People who have taken Earth Science will know this, but the Coriolis Effect is a physical effect that has to do with the rotation of the earth. When a plane is in the air, it is resisting the gravity that the earth uses to carry objects and keep them attached. This is why planes specifically going North or South will be affected by the rotation. This is why planes going so must aim slightly to the west to resist this force. This is a very weak force, but it still exists within the physics environment
Also, (this request is mainly for Global Flight) when a plane is flying east, it must make up for the rotation of the earth and sometimes have a longer flight time.
I mainly want this added to give a more realistic planning feel to the game
