A pilot direction indicator or pilot's directional indicator (PDI) is an aircraft instrument used by bombardiers to indicate heading changes to the pilot in order to direct them to the proper location to drop bombs. The PDI is used in aircraft where the pilot and bombardier are physically separated and cannot easily see each other. The Norden bombsight was originally designed with the idea of automatically directing a PDI and thereby simplifying the bombardier's task.
