***Link*** :: [Part 91 General Operating and Flight Rules](https://www.ecfr.gov/current/title-14/chapter-I/subchapter-F/part-91?toc=1) ***Description*** :: `= this.link` ***Author*** :: [[FAA]] These are the FAA's "General Operating Rules" governing how flight operations must take place. Most rules that a Private Pilot learns (everything from cruising altitudes, to airspace restrictions, to right of way rules) are found in the subsections of this part. By default, a flight operates under Part 91. But Part 119 explains the situations in which a flight must operate under [[Part 121]] or [[Part 135]] instead. #source #far
