Span load modification via differential spoiler setting

The serious impact of the wing tips vortices of a large aircraft is well known. There are many examples of the damage caused to following aircraft caught up in the rotational wake shed from an upstream craft. Topology of the wake vortices downstream of the configuration will largely depends on the s...
