Under Federal Aviation Administration (FAA) regulations, Part 135 governs on-demand charter and commuter flight operations, which have stricter pilot requirements than private (Part 91) flying. To serve as a Pilot in Command (PIC) for a Part 135 operation under Visual Flight Rules (VFR), a pilot must have at least 500 hours of total flight time, including 100 hours of cross-country and 25 hours of night flight. For Instrument Flight Rules (IFR) operations, the "minimums" jump significantly to 1,200 hours of total time, 500 hours of cross-country, 100 hours of night time, and 75 hours of actual or simulated instrument time. Additionally, pilots must hold at least a commercial pilot certificate with appropriate category and class ratings. Commuter operations carrying passengers typically require even higher experience levels and specific "operating experience" hours in the specific aircraft type. These strict thresholds ensure that charter passengers are flown by highly experienced aviators who have proven their skills across diverse and challenging flight conditions.
