  The formation of stars is usually accompanied by the launching of
protostellar outflows. Observations with the Atacama Large
Millimetre/sub-millimetre Array (ALMA) will soon revolutionalise our
understanding of the morphologies and kinematics of these objects. In this
paper, we present synthetic ALMA observations of protostellar outflows based on
numerical magnetohydrodynamic collapse simulations. We find significant
velocity gradients in our outflow models and a very prominent helical structure
within the outflows. We speculate that the disk wind found in the ALMA Science
Verification Data of HD 163296 presents a first instance of such an
observation.
