A cursorial approach to flight could be expected to work well on any planet 
that has gusting winds rather than uniform or no winds.  I can't imagine any 
planet with an atmosphere that wouldn't have gusts.  That doesn't imply that 
I think that the approach to flight was entirely cursorial, as the evolution 
of the 'flight' apparatus seems to me to be more related to increases in 
general mobility.
