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

Under night VFR (Visual Flight Rules), FAR Part 91 allows pilots to operate an aircraft beyond the limits set for daytime VFR conditions to ensure safe navigation and compliance with regulatory standards. The regulation stipulates that the maximum distance a pilot can fly under night VFR is limited to 100 nautical miles from the takeoff point. In some contexts, the regulation can be interpreted based on operational considerations, but typically, the limit cited for night VFR operations centers on how far the pilot can depart safely from the departure airfield, ensuring that they remain within a reasonable distance to manage visibility and flight safety in the darker conditions.

While the other distance options may seem plausible in certain contexts, they do not accurately reflect the specific guidance outlined in the FARs for night VFR operations, which emphasizes risk management and safety in reduced visibility conditions. The distance of 121 nautical miles is a common limit recognized for such operations, making it the appropriate answer.
