Description

This unit has been bench tested by an FAA certified repair station and it comes with an 8130 single release dated 06/03/2026.

• On-the-Fly TAS Calculation: Features a dedicated manual knob on the lower bezel paired with a movable altitude-versus-temperature alignment window. By rotating the dial to match current outside air temperature (OAT) and pressure altitude, the inner scale reveals true airspeed without requiring external flight computers.
• Failsafe Mechanical Drive: Relies entirely on an internal copper-alloy aneroid diaphragm mechanism that calculates air pressure differentials. The instrument provides continuous, unthrottled airspeed readouts during complete electrical system failures.
• Dual-Unit Scale Optimization: Provides immediate reference across both nautical and statute speed increments, simplifying navigation across older sectional charts, legacy manuals, or modern GPS avionics configurations.
• Linear Needle Calibration: Engineered with internal linkages that translate non-linear pitot pressure curves into smooth, linear needle travel across the dial, minimizing visual scanning errors during rapid acceleration or deceleration phases.
