The GTA propeller is produced and assembled under strict quality control. It uses a vernier control cable from the cockpit which is calibrated to give one degree of pitch change for each revolution of the control knob. The vernier is linked to a push rod which activates a cam system inside the GTA hub. The cam then turns the blades for a full 18 degrees of pitch adjustment. This gives the propeller the reliability of a totally mechanical system. The GTA does require a hollow shaft-type gearbox to accommodate the push rod. The GTA has a safety feature which will always return the blades to the fine pitch stop if the need should arise. A dual spring action applies pressure on the cam and hence the blades and fine pitch can be attained quickly by depressing the center of the vernier control.
