How much farther can an airplane be flown under night VFR according to Part 91?

Under Part 91 of the Federal Aviation Regulations, the rules regarding Night Visual Flight Rules (VFR) state that a pilot may fly an airplane under night VFR up to 100 nautical miles from the point of departure, as long as the aircraft is being operated with visual references to the ground and has proper lighting for navigation.

However, when flying at night, pilots are urged to have additional measures in place. The standard operation typically involves 50 nautical miles, but under specific circumstances, such as when a destination is not reachable within those parameters, rules may allow flying up to 121 nautical miles under night VFR, provided other regulatory conditions are met for navigation and visibility.

This figure of 121 nautical miles is notably based on various practices that accommodate safety while assessing operational limits without compromising adherence to IFR (Instrument Flight Rules) when conditions demand. Hence, the figure 121 nautical miles is recognized as a limit that enhances operational flexibility for pilots flying under night VFR conditions while ensuring adequacy in navigation practices in line with regulations.
