Key Technical Capabilities
  • Propeller De-Ice Monitoring: Continuously tracks the electrical current consumption of the propeller’s de-ice boot heating elements, allowing the pilot to verify that the system is shedding ice symmetrically.
  • Cycle Tracking Verification: Displays structural current fluctuations as the de-ice timer cycles power back and forth between the propeller blades, helping the flight crew immediately catch dead heating elements or timer faults.
  • High-Contrast Scale Layout: Features a highly distinct 0-30 Amp needle sweep against a deep black faceplate, engineered to provide quick glance tracking during high-workload IFR flight conditions in icing environments.
  • Integrated Night Visibility: Equipped with factory internal lighting circuits designed to evenly distribute glare-free illumination across the dial text, maintaining instrument legibility during night operation.
