Given the lack of non-assisted doublejumps anywhere else (like when all of team RWBY had to run up the falling pieces of the temple-thingy to not fall to what probably would have been their deaths), it's safe to assume that she, and probably pretty much everyone else, can't doublejump without using something else to create the necessary momentum.
