A study was made to evaluate competency of pilots trained in aircraft having a stability augmentation system. This is to determine the necessity of issuing restricted certificates to private pilots if they are unable to pass the private flight check by manual operation of controls. This project was to train five students to required flight performance for a private pilot certificate in a Cherokee-140 equipped with the Mitchell AK-153 Stability Augmentation System. When the students reached private pilot proficiency, they were given three flight checks. The first with the system on, the second with it off, and the third in a different aircraft without the stability system. All students passed the checks without difficulty. The results of the project indicate that all students reached private pilot proficiency in an average time. The stability system had no particular effect on the students control of the aircraft with or without visual references. Therefore, it would seem unnecessary to issue restricted pilot certificates.
