Electric Trim Systems: Design and Certification Considerations under FAR 23.677 (CAM 3.337-2) 730299

The FAA uses the Federal Aviation Regulations (FARs) as the criteria for the approval and certification of all aircraft and appliance designs. In addition to assuring that systems will perform their intended function, the FARs attempt to maximize safety and utility.
