A nozzle vane (18) includes a row of trailing edge apertures (34) and cooperating inboard slots (36) joined in flow communication with a mid-chord cavity (38). An outboard slot (46) is spaced outwardly from a respective last one of the inboard slots, and outboard of a respective last one of the trailing edge apertures. The outboard slot extends behind a braze joint (24) between the vane and a supporting band and is effective for backside cooling thereof.
