11.7 Analogue Tachometer (all J-Series)
11.7.1 Description
 Jabiru Aircraft may be equipped with an analogue tachometer or a digital RPM read-out as a part of
an engine monitoring system.
 Analogue tachometers are driven by a variety of sensors, depending on the aircraft model. In some
the sensor is positioned so that the teeth of the flywheel ring gear pass close by and produce a
signal. In others the same sensor reads off metal tags bolted to the flywheel. Finally, in some
aircraft a sensor is mounted on the alternator mount plate and produces a signal from the ignition
magnets.
 Refer to the Engine Maintenance Manual for additional details.
