It doesn't have to continue to sink forever. It can stabilize its position at some point. It will sink indefinitely unless some other force acts to stop it. In theory, it will sink until it reaches the ground. In other words, in theory, an aircraft lays down a swath of downwash from the time it leaves ground effect on the runway until the time it lands in ground effect again. The entire swatch theoretically touches down on the ground eventually. E.g. if the vertex radius is 15 feet and sink rate 20 fpm, we hit the wake after a 30 second turn. Twenty feet per minute is too slow. The downwash will move at at least a few knots, and even three knots is 300 fpm. -- Transpose mxsmanic and gmail to reach me by e-mail. |
