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 (Section 23.2
). Each of the
sensors must be correctly installed and configured (Section 33.4.19
for GDU 37X systems and
Section 34.4.26
for GDU 4XX systems) prior to use.
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.
