ETM1000 Exceedance & Trend Monitor

The AKV Exceedance and Trend Monitor ETM1000 is an Engine Data Acquisition Unit (EDAU). It provides legacy operators with a highly effective and affordable means to monitor and record all drive train parameters for exceedances and trending. The ETM1000 is the only system available that is programmed with the complete Rotorcraft Flight Manual (RFM) operating limitations and helps prevent an exceedance from being recorded by providing alert tones to the pilot in conjunction with panel mounted pushbutton annunciators with caution and warning indication. A dedicated instrument panel mounted power check pushbutton and health indication is also provided.
