H.4.19.4 Input Configuration Items Requiring Calibration
Fuel Input Calibration – The G3X has two fuel calibration curves, the standard ‘in-flight’ or normal
flight attitude calibration curve and an optional ‘on-ground’ or ground/taxi attitude calibration curve. The
ground/taxi calibration curve can be used for aircraft that have a significantly different attitude when on the
ground, such as tailwheel aircraft. If no calibration data is entered for the ground/taxi curve, the normal
flight calibration curve will be used when the aircraft is in flight and on the ground. The calibration curve
being used to display fuel quantity switches automatically and is determined by GPS groundspeed,
indicated airspeed, and height above ground.
