- In aeronautics,
downwash is the
change in
direction of air
deflected by the
aerodynamic action of an airfoil, wing, or
helicopter rotor blade in motion...

birds after can take the

force due to the
wingtip vortices at the tip of the
wings of the lead bird. The

underwash part
behind the bird, and at the same time they have an
upwash on the outside, that
hypothetically could aid the
flight of a
trailing bird...
-
operator error,
where the
pilot drops the
craft too fast
resulting in the
upwash at the
rotor hubs that can lead to
vortex ring state.
