Tachometer (Rpm) - Garmin G1000:Beechcraft Baron 58/G58 User Manual

ENGINE INDICATION SYSTEM

TACHOMETER (RPM)

The Tachometer is located beneath the Torque gauge and displays the propeller speed in revolutions per
minute (RPM) from 0 to 2500. A propeller overspeed is indicated if the propeller speed exceeds the maximum
safe operating speed (red tick mark). The Tachometer is equipped with a propeller sync indicator, which points
towards the higher-speed propeller. The indicator changes linearly with RPM difference between the left and
right propellers. A full diamond is displayed when the propellers are synchronized and transitions to a full
arrowhead when the difference is greater or equal to 50 rpm.
