Description

This unit has been bench tested by an FAA certified repair station and it comes with an 8130 single release dated 10/20/2025.

Key Technical Capabilities
    • Propeller Speed Tracking: Dynamically processes engine or governor-derived tachometer signals to display precise propeller rotational speeds, allowing flight crews to accurately set and monitor cruise configurations. 
    • Symbiotic Engine Management: Provides clear, non-glance visual sweep resolutions to help pilots avoid structural harmonic or over-speed conditions, ensuring operation remains within airframe limitations.
    • Vibration-Damped Movement: Employs an internal mechanical layout engineered to absorb standard piston or turboprop vibration envelopes, preventing needle float during high-power takeoff or climb sequences.
    • Cluster Integration Optimization: Built with a space-saving outer casing profile designed to stack seamlessly into secondary engine parameter rows or multi-gauge panel matrices.
