Plain English Meaning

Flying at night under visual flight rules — meaning you are still navigating by looking outside, not just at the instruments — but doing it in the dark, which brings its own equipment, weather, and pilot requirements.

Full Definition

Flight conducted at night under Visual Flight Rules, where the pilot navigates and maintains aircraft control primarily by outside visual reference rather than by instruments alone. It requires compliance with night VFR weather minimums, carriage of required aircraft equipment for night operation (including position lights, an anti-collision light system, and an adequate source of electrical energy for installed equipment), and pilot night requirements when carrying passengers.
