I believe the final solutions for airliners would be using LIDAR to detect airflow in front of the plane based on the particles in the air. There's a few scientific articles about it if you search, and I believe from second hand information that the big manufacturers (airbus and Boeing) are testing prototypes for deployment on next gen airliners.
