Part 91
Part 91 of the Federal Aviation Regulations or FARs is one of two main parts dealing with the certification of pilots their starting point until being hired by an airline or charter company. Unlike Part 135 and 121 which deals with the certification and operation of flight charter companies, airlines, and commercial aviation businesses Part 91 deal primarily with the pilot and the pilots rules and regulations for most aspects of flight. Perhaps one of the most import rules in Part 91 is FAR 91.03 which determines whom is the pilot in command of an aircraft.
