5.6.3 G900X/G950 Supported Turboprop Engine Sensors
Table 5-8 contains a list of G900X/G950 supported sensors.
CAUTION
Table 5-8 contains the sensor manufacturers and part numbers that have specifically been
tested and verified for use with G900X/G950. Required sensor properties are listed for
sensor types with standard electrical parameters configured as part of the default
G900X/G950 software configuration. Use of an alternate sensor is done at the installer’s
own risk. Garmin cannot guarantee suitable performance when an alternate sensor is
used. Garmin strongly recommends the sensors listed in Table 5-8 be utilized in all
installations.
