Although not a US citizen, I have had the pleasure to attend factory conversion courses on CV880M, B707, L1011 and B747 airplanes prior to my retirement from aviation. To obtain qualifications to operate these aircraft, I had to satisfy the FAA that I understood the FAR's before the issue of a license, so I am very familiar of the pertinent FAR's.
My Google says thus:The Federal Aviation Regulations, or FARs, are rules prescribed by the Federal Aviation Administration (FAA) governing all aviation activities in the United States. A wide variety of activities are regulated, such as airplane design, typical airline flights, pilot training activities, hot-air ballooning, lighter-than-air aircraft, man-made structure heights, obstruction lighting and marking, and even model rocket launches and model aircraft operation. The rules are designed to promote safe aviation, protecting pilots, flight attendants, passengers and the general public from unnecessary risk.
Have a good day sir.
