hmmm.... 1600km/h is ~400m/s, if what you say holds, then someone that jumps from a 1.5m wall to the ground stays in the air for ~0.5s, which means that the ground has moved by 200m in that time...?
From physics, Coriolis is a force that is exerted at a body that moves (even at constant speed) in a rotating reference frame. The speed is constant but the direction changes (due to the fact that you are on a rotating reference frame), so a force is needed to make equations right --> coriolis force. Greater the speed/angular speed the greater the force.
Apparently it's the reason that rail tracks are not evenly worn in trains that travel north-south (subtle effect). The effect on aviation is not the one you mention I believe. I think you are mixing the coordinate frames. Someone with better physics background can explain it better.
