Propeller Sync Configuration - Garmin G3X Touch Installation Manual

34.4.26.32 Propeller Sync Configuration

If two EIS LRUs are configured, and RPM is configured for twin-engine display, a graphical propeller
sync indicator (syncrometer) can be configured to display on the RPM gauge. As with a traditional
mechanical syncrometer gauge, the propeller sync gauge spins in the direction of the faster-turning engine
when propeller RPM is not synchronized. The Propeller Sync Configuration page allows the propeller sync
indicator to be enabled or disabled, and the maximum RPM difference to be configured. Smaller values for
the Maximum Difference field make the propeller sync indicator more sensitive.
