Annunciator Control Unit For King Avionics

This interface and annunciation device combines navigation source switching to the pilot's primary CDI or HSI with key GPS selection and annunciation functions. The MD 41 provides up to 19 user defined relay poles. The unit weighs 0.7 Lbs. Lighted push buttons and daylight readable annunciators make the MD 41 popular with pilots and technicians. Positive feedback from the ACU's push-buttons ensures safe accurate operation, even in rough IFR conditions. Push-button lighting level is controlled by the instrument lighting rheostat. The legends are permanently molded into the face of the selector buttons to prevent wear. Annunciator lighting is automatically dimmed by means of a photocell feedback circuit. The MD 41 is certified to FAA TSO C129 standards. This is the same comprehensive TSO to which all approach-certified GPS receivers have been approved. The MD 41 ACU's are shipped with a connector kit and installation hardware. A full size panel cutout template is provided in the installation manual.

• Transfers Navigation display between VOR and approach certified GPS systems
• Professional appearance - replaces switch and relay wiring
• TSO C129 Approved to meet NEW FAA field approval requirements
