Speel’s Pilot Display Unit (PDU-39) is a fully digital, raster-based Head-Up Display (HUD) with a 23° total field of view. The unit features continuous built-in-test for instantaneous system status monitoring. The up-front control panel (UFCP) such as the one featured here* is a separate LRU that mounts on the PDU-39 and connects electrically to Speel’s MP-39 Mission Computer to provide control functions of the PDU-39 such as brightness and displayed HUD modes. The PDU-39 unit is supplied as a single LRU and designed for rack-mounting, thus allowing for easy interchangeability and mechanical alignment, and connects to onboard power and avionics systems via a single Mil-specs connector located at the back of the unit.
