A method for assembling wings includes supporting a pair of wing spars, which include a plurality of coordination features, upon a pair of stanchions in a generally horizontal position. A plurality of ribs and wing panels are accurately fastened to the pair of wing spars at a first workstation using the coordination features to position accurately the parts. The combination is transferred to downstream workstations via a ground transport vehicle for further processing and assembly to define a pulsed flow wing assembly system.
