23 ENGINE/AIRFRAME SENSOR INSTALLATION
23.1 Engine/Airframe Sensor Options
Table 23-1 lists the types of engine/airframe sensors that may be used for the various engine/airframe
inputs. Many of these sensors are included in the Garmin G3X Sensor Kits (
). Each of the
sensors must be correctly installed and configured (
for GDU 4XX systems) prior to use.
NOTE
In addition to the engine sensors listed in Table 23-1, the G3X system can also work with
many other sensors (not listed) that output a compatible signal, refer to the sensor
specifications to determine compatibility.
