The Dual Indicator for Nr (Rotor) and Np (Free Turbine) is designed as a direct replacement for the rotor only indicator. Customers that have installed the Np tachometer generator on the engine gear box for the AKV Ng/Np cycle counter can now display the Np speed in addition to Nr. This indicator is also a direct replacement for the AS350B1 and B2 (Non-VEMD) dual indicator. For many operators of the Arriel 1 engine and in conjunction with the AKV Cycle Counter, indication of the NP speed to the pilot will further enhance overall safety.
• Np (free turbine) and Nr speeds
• Face plate design as with the current AS350B2
