So seeing as my job involves being outside for long periods under the glide path to one of O'Hare's shorter runways (9L/27R), I've had great opportunity to observe the various aircraft on approach. One thing I've noticed is the tendency of MD-80 variants to leave more and stronger tip vortices than other light aircraft*. Today one was trailing in a clear blue sky. Is there a particular design reason for this?
