This function is useful for helicopters as it returns Z vector like an indicator of thrust/load ratio. More or less climb (+) or descent (-) tendency but: As X,Y,Z vectors are relative to vehicle attitude, this function doesn't return a climb or descend rate (as the attitude of the vehicle can be far from horizontal). You can get negative Z vector, in jets, while climbing fast, peeling off in the sky! More or less, you can use as a Z accelerometer factor but invert the sign: +G acceleration (negative vector below the jet) is -Z here.
